When a vehicle makes a turn, the two front wheels trace out two arcs as

shown in the figure below. The wheel facing towards the inside of the

turn has a steering angle that is greater than that of the outer wheel.

This is necessary to ensure that both front wheels smoothly trace out

two arcs, which have the same center, otherwise the front wheels will

skid on the ground during the turn.

During a turn, do the rear wheels necessarily trace out the same arcs as

the front wheels? Based on your answer, what are the implications for

making a turn close to the curb?
