Home › CDL Practice Tests › Combination Vehicles Questions › Question 234
Why should you avoid passing on the right or squeezing beside another large vehicle with a combination?
- A.Your trailer's off-tracking and swing can close the side gap without you feeling it, and the other vehicle's blind spots hide much of your outfit
- B.Side space does not matter for professional drivers
- C.Trailers never move sideways once rolling
- D.Passing on the right is always the safest option for trucks
Correct answer
A. Your trailer's off-tracking and swing can close the side gap without you feeling it, and the other vehicle's blind spots hide much of your outfit
Why
The space beside you is used by the trailer's tracking and by any sway, so a gap that looks adequate at the cab can vanish at the rear wheels. Keeping side margins is as important as the gap ahead.
