Properly adjusted outside crossover mirrors should show which part of a school bus?
Correct answer: C. – The left and right front tires where they touch the ground
Crossover mirrors must show both front tires where they touch the ground. They should also show the ground-level area in front of the bumper until it overlaps with the driver’s direct view, along with the area extending toward the service door. Rearward traffic is monitored using the exterior side mirrors.
