I drove our SUV into an underground car park.
Going in I was going very slowly - about 5kmh (as I noticed the 1.8m clearance sign and steel bars to protect the ceiling)and it went through just fine. 45min later I returned to the car and proceeded to another exit where the clearance was 1.9m. that exit however was chained off. I went back the way I came in from at about 10kmh(going out that exit didn't have a notice for height) and that's where the awning came in contact with the steel protector and it tore of my roof rails (they basically broke) and my awning. The awning is salvageable but not the roof rails or roof rack.
Looking at at exit now from outside, there is a bit of an angle so there's less height in the exit lane than in entry lane. Measured the height in exit lane and it comes to 1.9m.
Bit of a grey zone in my opinion. Using my usual exit I would have been fine, and at the exit lane I was forced to use the height was less than the height of my usual entry lane.
A: entered the carpark - no issues
B: parked - later reversed out and proceeded to C
C: Exit chained off - had to reverse and return the way I came
D: the clearance in the exit lane is less than in the entry lane
