Driving SafelyQuestion 45 of 60
What is off-tracking (or cheating) in a combination vehicle?
a.The rear wheels follow a shorter path than the front wheels when turning, tracking inside the turn
b.The trailer swings wider than the tractor
c.The tires lose air pressure
d.The trailer brakes lock up
Explanation
Off-tracking is when the rear trailer wheels follow a shorter, inside path compared to the front wheels during a turn. The longer the vehicle, the more the rear wheels off-track. Drivers must swing wider and steer the front of the tractor farther out so the trailer wheels clear curbs and obstacles.
