Which ground contact points should be visible in properly adjusted outside crossover mirrors?
Correct answer: C – The right and left front tires touching the ground
Crossover mirrors should show the front danger-zone area from the bumper at ground level to where direct vision becomes possible. Their views should include both front tires touching the ground and the area toward the service door. Rearward traffic is monitored with the flat and convex mirror systems.
