Tractor-Trailer Vehicle Combination Rollover Risk Factors
What is the most likely factor that causes a tractor-trailer vehicle combination to roll over in a turn?
A) Double 48-foot trailers
B) Triple 28-foot trailers
C) Single 53-foot trailer
D) Flatbed trailers
Answer:
Double 48-foot trailers
Explanation:
The correct answer is A) Double 48-foot trailers. A tractor-trailer vehicle combination is most likely to roll over in a turn when the configuration includes double 48-foot trailers. This is because longer trailers have a higher center of gravity, making them more prone to rolling over during sharp turns.
