When making a right turn with a combination vehicle, why should you be especially cautious?
a.Because the engine loses power in turns
b.Because off-tracking causes the rear wheels to follow a shorter path, potentially running over the curb or hitting objects
c.Because the trailer brakes activate automatically in turns
d.Because the mirrors cannot show the right side
Explanation
Off-tracking is especially dangerous in right turns because the rear wheels cut the corner more sharply than the front wheels. The longer the combination, the greater the off-tracking. Drivers must swing wide enough to avoid running over curbs, pedestrians, or objects.
