What share of combination-vehicle rollovers are linked to taking a curve or ramp too fast?
- A.Almost none, rollovers are mostly from tire failures
- B.Only rollovers on straight roads are speed-related
- C.Speed in curves is rarely a factor
- D.A large share; entering curves and ramps too fast is a leading cause of truck rollovers
Correct answer
D. A large share; entering curves and ramps too fast is a leading cause of truck rollovers
Why
CDL material stresses that many rollovers happen on ramps and curves entered too fast, often below the posted limit for cars. Setting speed before the curve is the main defense.
