Double Roundabout Accident Question

Hi fellas here's another question for you all.

(Driver A - Tesla - Right lane - Orange MS Paint Line)
(Driver B - Mustang - Left lane - Blue MS Paint Line)

Driver A enters roundabout (two lanes) from right most lane with intention to turn right.
Driver B enters roundabout from left lane also indicates to turn right.

Lane markings show

  • Right lane must only turn right
  • Left lane can go straight or right.

Driver B makes a uturn throughout the roundabout.
Driver A turns right and in doing so goes through outer most lane in the roundabout.
Driver A's front left impacts Driver's B's side.

So who is at fault?

Edit: Comprehensive insurance claim sent.

        Mustang wouldn’t be entering the same lane as the Tesla. Why would it need it give way. Regardless, they could have entered the round about at the same time and Tesla would have caused the same accident.

        • +2

          No, because there are lights at three of the entries that stagger the time of entry to the roundabout, and the lights are specifically there to prevent the scenario you describe.

          • +1

            @Browsers: Those lights only operate during peak hour, so the scenario I described could still happen.

            • +2

              @afayd: Eddyah's comment still stands. They'd be failing to give way to any traffic already on the roundabout. Look at the lane markings at that specific location - this is where the original design layout intends for the Tesla to pull across to the left on the approach to Underwood, doing so safely because the lane occupied by the Mustang was not permitted to turn right.

              • +1

                @Browsers: Did you not read my reply? Both could have entered the round about at the same time and Tesla would have caused the same accident.

                It is illegal to move into a lane that’s already occupied.

                • +1

                  @afayd: If they both entered from Australia Ave, entry markings show the far right lane can only turn right, so cannot exit straight on to Underwood. Both entry lanes from Aus Ave are also permitted to turn right onto Homebush Bay Drive, and if the collision happened at that exit fault would not be in question because the markings at that exit are clear and provide for both lanes to exit simultaneously.

                  • +1

                    @Browsers: I am not talking about both entering from Aus ave. I am talking about the case I drew, where both can simultaneously enter, mustang would be legally doing a right turn but the Tesla would still be smashing into it and causing the accident.

                    • +1

                      @afayd: Yeah, that is the scenario I already replied about.

                • @afayd:

                  Both could have entered the round about at the same time and Tesla would have caused the same accident.

                  If this was true, the car would be WELL AHEAD of the other car and not have the problem.

                  However, if you're gonna try go on about how the car could slow down such that when the Tesla exits it's in fact blocking the exit, then that car would STILL be at fault as they didn't give way to other cars entering the round about. This is true for all round abouts but it's less like the incident would occur because the Tesla would be more wary of that car's behaviour.

                  The only edge case is if traffic had halted and you plowed into a stationary vehicle.

                    How can the Mustang STILL be at fault when they both enter the roundabout at the same time and one doesn’t have any more right of way than the other. Mustang would be in its lane and the Tesla would be crossing over. You are being an undiluted moron.

                      Because you ALWAYS GIVE WAY TO YOUR RIGHT on a round about - that's a very basic road rule you seem to be unfamiliar with.

                        @eddyah: Oh wow.. you truly are a moron. That rule applies when /entering/ a round about; if you haven't already entered, you give way to the car that is coming from the right. Not on a double lane round about when two cars have already entered their respective lanes. The car that's switching lanes must give way to the cars in the lane it is trying to switch to.

                          if you haven't already entered, you give way to the car that is coming from the right.

Let me explain it as if I'm explaining to a moron: one is with regards to two vehicles entering the round about at the same time from two different entrances in a way that there there is no issue of giving way, and the other is with regards to two vehicles entering the roundabout sequentially, where the second car has to give way to the first car, provided that it is coming from the right.

                          @afayd: I am pretty sure there is no specific rule in NSW to give way to your right on round abouts. The rule is to give way to cars already on the round about, not just to those on your right. This means you must give way to vehicles coming from your left and straight ahead as well. The 'give way to your right' may be a courtesy to help traffic flow, but it is not a specific rule.

    Mustang is an idiot for attempting a U-turn from the left lane however he is technically allowed to do that and therefore the Tesla is in the wrong for not giving way whilst in the roundabout.

    Solution: Ask NSW Roads to put a U-turn arrow in the right lane before entering the roundabout to make it clear that U-turns can only be performed from the right lane.

  • +1

    I have read the post but let me guess,

    Its the roundabout at DFO homebush.

    Am I right?

  • my question from the video is "What about the 'Open Frunk'" shown on the Tesla graphic !?

    From the Paint lines crossing the Tesla is at fault for failing to get into the left lane before turning

    and crossing another lane too late without giving way to the Mustang in that lane

    and also being an idiot not paying attention to the Mustang clearly indicating a right turn seconds before

    I will read others comments next …

    [A FEW MOMENTS LATER …]

    Okay - having read lots of quoting road rules saying Mustang was at fault, what I learned from driving in Athens Greece where there were no lanes and no apparent road rules followed with cars drifting across all directions, my advisor told me it was simple - 'merge slowly and avoid hitting another vehicle'

    On that basic biology - when on the road you should pay attention to all around you - doesn't the Tesla have 360 degree display ? - to avoid collisions

    As a driver if you assume everyone knows and follows every arcane road rule then you are just a collision waiting to happen.

    I'm guessing insurance companies don't care and will payout if the OP has comprehensive cover (and his premiums will rise steeply next year!).

    As someone who rode motorbikes for 10 years (and woke up in hospital traction after me and my girlfriend on pillion smacked into the side of a car doing a totally illegal U-turn on an 80kph section of highway on the blind crest of a hill) I used to advise learner motorcyclists to "assume everyone around you is trying to kill you"

    Folk who assume others will do the right thing are a danger on the road.

    Bad Tesla !

      You can bold it as much as you like, you're still completely wrong.

      Aerial imagery of roundabout clearly shows permitted line of travel on the left lane. STRAIGHT ONLY.
      You can't turn right from the left lane unless the markings specifically say you can do so (ie by restricting the right lane user to a must turn right scenario).

      You are 100% wrong. best if you just delete your post to avoid further embarrassment.

      • +3

        Aerial imagery is how it /previously/ was. Not how it is now. Did you even bother to look at the video shared by the op to see that the left lane also has a right arrow on it?

        • +1

          Point taken for the first exit… yes, the outside lane has the right to go straight or right, and the inside lane is restricted to right only.

          But where the collision actually occurred, NO SUCH MARKINGS! They are in a roundabout! The fact that some of the entrances are controlled by lights to better control traffic flow makes no difference. All throughout the dashcam video are signs indicating that it's a roundabout. There are NO signs indicating the outside left lane can continue around to the right on the 2nd exit.

      • Stick to flying round in your UFO, you have no place on planet earth with you substandard driving knowledge!

        • +1

          IT'S A ROUNDABOUT! The fact that some of the entrances are controlled by lights doesn't change all the signage everywhere else!
          I await the update for the OP after the assessor sees the video, and then your apology :).

  • Both drivers are wrong imo - wouldn't be surprised to see the insurance companies share repair costs.
    Tesla in right lane should have not exited roundabout without first checking the other lane to avoid collision. Any car could have been in that other lane, including a car already on the roundabout.
    Mustang in left lane should have done U-turn only from right lane.
    Also agree that roundabout is poorly designed.

  • -1

    The mustang is on the wrong lane to turn right.

  • +4

    I am baffled by all the people referring to the Mustang doing a "U-turn".

    No-one was doing a U-turn. This was simply a case of two vehlcles, one in each lane on a road. The one in the right lane tried to turn left from there, and collided with the one in the left lane. It happens it was on big roundabout, but that's irrelevant.

    Even if the Mustang shouldn't have been there, the driver of the Tesla should have looked, seen that it was, and not tried to do a left turn from the right lane. You can't drive as if other road users are doing what you think they SHOULD be doing, you have to drive according to what they ARE doing. And given the lane markings there I can't see why the Mustang didn't have every right to be there doing what it was doing.

    • -2

      How many exits on this roundabout mr big brain?

      I count 4 and when you drive with google maps, it calls turning left the 'first' exit but for the OP, the chance to turn left has already passed according to the markings on the road.

      So we have:

      the mustang can take the FIRST or SECOND exits (go straight or turn right).
      the tesla can take the SECOND or THIRD exits (turn right or U-turn).
      

      Mustang will ALWAYS impede the tesla if he attempts to take the third exit (mustang at fault)
      Tesla will ALWAYS impede the mustang if he attempts the first exit (tesla at fault)

      Clear with these failure scenarios?

            @eddyah: i really didnt want to post here again cause its over… but here i am because you are really Mr Small Brains

            the exit i linked to above is what you have called the third exit, this is the exit the TESLA could have exited safely as you keep saying he could never get off and would go around in circles for ever on the roundabout. If he wanted to use the second exit, where the accident occured, the Tesla needs to give way and exit safely not ram into the Mustang.

            Here is second Exit: https://imgur.com/a/6cX2a8B

            I think the main issue you have is you have zero understanding what the lines on the roads mean or even what the arrows drawn on the roads entering the roundabout means.

            • @SpendLess: Haha you have to edit your posts to make a point?

              Here is second Exit: https://imgur.com/a/6cX2a8B

              That is the same exit (which you've conveniently swapped out) which i'm referring to (not the line, the DFO road which is Underwood road) and this is the second exit that the Tesla was trying to take before the Mustang got in his way.

    100% Mustang fault. Give to insurance, let them educate them.

    You can't go around the outside of a roundabout like that.
    All the voters claiming otherwise need to go hand in their licence immediately.

    Look at aerial imagery of lane markings at roundabout. Mustang had already broken the law at the first exit (was not entitled to turn right at all). Tried his luck again at the second exit and found out exactly why that turn is illegal. Show insurance the dashcam and the aerial shot of the roundabout. 150% clear Mustang at fault.

    • +1

      lol this comment. Mustang very much could turn right.

      • Except he didn't - he chose to do a U-turn instead.

        • +1

          U Turn or right turn. Same same. The lane that could. There’s no legal reason why it can’t also be a U turn either (as supported by the outer lane directing cars off the roundabout on the exit after the crash).

          • @Tman81: Wow if you think they are the same you are an idiot.

              @eddyah: That's not a roundabout. It is idiotic to draw analogies between the two. You cannot do a u-turn at an intersection in NSW unless specifically allowed, but you can on a roundabout. Eddy, you truly lack basic reasoning skills.

              • @afayd: LOL good you're starting to at least see why it's not a good idea to do it from the left lane.

                It's effectively the same logical reasoning if you turn your brain on. Don't do a U-turn from the left lane. It's very simple and if you can understand why you shouldn't in this example where the same reasoning applies, I'm afraid I can't continue discussing this point with you.

                  @eddyah: Ah, if you turn your brain on, don't switch to a lane that's already occupied and cause an accident. Worst, don't cross over it.

              @eddyah: Ok we will use this picture of yours and put it into OP's Case

              Tesla is on the right lane just like he is on the roundabout… He goes straight and hits the car on the left turns right because just like in OPs case the road shows he can turn right

              SO WHO IS AT FAULT?!

        • You think he can do a U-turn from the left lane on a dual lane road?

          • +1

            @UFO: Yes he can.. see the link below this is Australia Ave a road that enters this round about. Now lets pretend this is where the Mustang and Tesla is driving on instead of the other street which is on the right. See the left lane it indicates the driver can go straight or turn right, this will be the Mustang car when he enters this roundabout. The Right lane indicates it can ONLY turn right, which will end up being the Tesla lane when the car comes onto the roundabout. The exit straight in front of this picture is where the Tesla and Mustang had their accident.

            So tell me if they came from this entrance instead who is at fault? as the road here shows you that this roundabout the right lane must turn right and the left lane can also turn right/u-turn or go straight.

      Can’t assume. That stupid road needs clearer markings.

      When entering, as the vid shows, both lanes have arrows saying they can go right. But then no arrows after.

    surprising how most people think that its the mustang's fault. confusing round about but Tesla has to give way when exiting

  • +3

    Not sure why most say mustang is fault. If you're on inner circle you have to first come into outer circle before exiting by giving way, not straight cross. That being said i am not familiar with this area or any specific local road rules around it. The road markings show outer lane can exit or go straight through where the inner lane is for right turning etc.

    But yeah interesting to see what the outcome is.

  • +5

    -voted tesla
    -crossing the other lane to exit it is wise to give way
    -better to turn left from the left lane if there are no signs

    Same thing happened to me same dfo round-about, same situation, but I was outer lane turning right and ahead of inner lane going straight, insurance ruled for me outer lane. Dash cam also showed inner lane never indicated left arrow for their intention to go straight

    • I think that settles it.

    • -2

      It's a different situation in your case. Yours occurred at the first exit, whereas the OP's incident happened at the second exit. On a double-lane roundabout, vehicles in the inner lane are not permitted to go straight.

    Looks you'll be getting a new intersection. Though not anytime soon. Wonder how they gonna do the traffic switches for the change.

  • 1) How big is this roundabout? Would each car know which entrance another car entered the roundabout from to have an idea of which line markings applied to them?

    Seems to me all of us here are commenting from the advantage of having an aerial view of the roundabout AND the opportunity to become familiar with the scenario which a first time or infrequent user may not have.

    2) I am still of the opinion that you should be in the left lane (and indicating left) to exit a roundabout. Where there may be more than one lane permitted to turn left, it would make sense to me that the car needing to cross through another lane (the outer lane) to exit, would need to give way to another car already in that lane. Even if you indicated your intention to turn left/exit from that inner lane, I am sure you can't just drive into/cut another car off in that outer lane, even if they are not supposed to be there.

    I would think that a car who entered from the left is supposed to either turn left at next exit or at most straight ahead if line markings allowed. In saying that, if on a big roundabout, each car probably doesn't know from where each car entered, so all cars need to rely on road markings and general roundabout rules whilst also remaining vigilant about acts and omissions of vehicles around you.

    I would think if you wanted to turn right or go around the roundabout, on a multi lane roundabout, you would enter from an inside lane then move to left as you approached your desired exit.

    As some roundabouts have more than four entry/exit points, it makes sense that basic roundabout rules and etiquette would prevail if ever in doubt. Sometimes it is not as straight forward as turning right/left or "u-turn".

    3) Have we actually established what the correct answer is for this particular scenario or is there still some indecision/uncertainty?

    If/when we are sure of the correct answer, could someone please publish it in an obvious place or perhaps in the OP please?

    Now he has, and I've seen it, I haven't changed my opinion in the slightest. It shows exactly what the google overhead shot showed about the lane markings around that roundabout.

    Look at 1:00 into the video. It shows that the lane lines there allowed the Mustang driver in the left lane to continue around the roundabout. It shows they did REQUIRE the Tesla driver in the right lane to change lanes to the left to exit there. And in doing that he got run into by the Mustang. Its about as clear a case of an unsafe lane change by the Tesla driver as you could get.

    You can't make a left turn from the right lane when there's someone beside you in the left lane.

    I don't expect the Tesla driver will come back and admit the insurance company has found him at fault.

    • Gordon'D, I've agreed with you (and upvoted) the whole way through.

      I was just going by the basic roundabout rules (and what is common sense to me) I learned when I got my license but there are so many different interpretations here, I began to doubt what I thought I knew and considered maybe the rules had even changed!

      Thanks for your contributions.

        to be fair majority of double road roundabout would be left lane, Mustang, either turns left or exit straight/next exit and will have a solid line further up showing they need to exit while the right, Tesla, can exit straight and turn right which is why i think this post is so divided and the voting went one way. Also because we cant change our voting after we voted.

        But thats the thing about driving you need to be aware of your surroundings (other cars & road signage), changing road conditions and not drive on autopilot else you are just a road hazard.

      Oh no! Is OP the Tesla driver, the car we believe to be in the wrong? (As opposed to what the poll suggests?.

      Oops. That could be awkward.

    From the view in the dashcam footage, the Tesla driver in the right lane is clearly at fault. Unsafe exit of roundabout from right-hand lane. They should have given way to the vehicles already in the left-hand lane. It's unclear if they were indicating from the video. There's nothing to suggest that the left lane must exit at that section of the intersection and the lane markings clearly show vehicles should only be exiting from the left-hand lane. This should be commonsense for all drivers - keep left!

    Tesla is at fault, your changing from the second lane, you should have been in the outer lane

    This is an interesting discussion - what if another car entered the roundabout from a later entrance in the left lane, and were going further round than the Tesla, wouldn't the Tesla be at fault for not giving way? Is that any different to what happened here? If there were more than 4 exits, what defines a U-turn?

    You are. The arrow on the road says that you can only go right, not straight ahead.

    The Mustang was indicating right the whole time, Tesla driver ignored and cut across. Tesla at Fault.
