Lesson plan
Bus trap
A bus trap (car trap in the UK) is a metal grate placed over a ditch or pit in the road with tines (sides) spaced far enough apart that small, shorter-axled vehicles fall between the sides, but longer-axled vehicles, such as buses, may pass. Cycles may cross broader-sided examples. Different versions exist for restricting access. The tines cross the path of the road, not parallel with the road direction. Small-wheeled vehicles bottom out in between the tines, preventing the vehicle from continuing over the obstacle.
