If you must make an emergency maneuver, which choice best protects a combination from rollover?
- A.Brake firmly in a straight line as much as possible before steering, and keep any steering input as small and smooth as conditions allow
- B.Steer fully first, then brake hard in the turn
- C.Release all brakes and steer sharply
- D.Close your eyes and hold the wheel locked
Correct answer
A. Brake firmly in a straight line as much as possible before steering, and keep any steering input as small and smooth as conditions allow
Why
Straight-line braking keeps sideways forces low while speed comes off. Steering hard while braking hard combines the two forces that roll trailers and lock wheels.
