BTW it happens everywhere even here in US even after having signs and all the cross checks.
Other day a truck carrying construction crane parts hit over pass. The crane pieces weighing 1000 of lbs fell off and a van was crushed between the cranes parts and bridge columns. The passenger in the van died. I remained stuck in traffic for 6 hours as the major highway was blocked due to accident.
Some bridges while all tunnels have senors before entry.. which turns the big lights red at the entrance of the tunnel or bridge if they detect a height issue.
