Trucks that ignore “low clearance” signs

...make for cool videos. I can’t believe that no one has come up with a solution for preventing this kind of accident. Should not be too hard. For example: Measure the truck height in advance and extend tire-killing spikes if it exceeds the limit (admittedly, this might cause other kinds of accidents). Or a GPS-based gadget that emits a warning sound if a low clearance location is close, to be installed in large trucks. [Source: Boing Boing]
