Home › CDL Practice Tests › Combination Vehicles Questions › Question 195
Why is it dangerous to cross tracks diagonally or to straddle two lanes over a rough crossing with a long trailer?
- A.Diagonal crossing shortens the distance, so it is safer
- B.Tracks are only dangerous when crossed straight on
- C.The combination can rock or shift, and a rough or angled crossing increases the chance of hanging up, shifting cargo, or fouling an adjacent track area
- D.Lane position has no effect on a trailer at a crossing
Correct answer
C. The combination can rock or shift, and a rough or angled crossing increases the chance of hanging up, shifting cargo, or fouling an adjacent track area
Why
Crossing squarely and in your lane keeps the outfit stable and predictable, and keeps every part of the long vehicle where other road users and the train's clearance envelope expect it to be. Rocking a long trailer over a hump also raises the hang-up risk.
