Home › CDL Practice Tests › Combination Vehicles Questions › Question 67
If your trailer starts to sway or swing while driving, what is the safest first response?
- A.Brake hard and steer opposite the swing
- B.Ease off the accelerator, hold the steering steady and straight, and let speed fall gradually without hard braking
- C.Accelerate to pull the trailer straight
- D.Turn quickly from side to side to cancel the sway
Correct answer
B. Ease off the accelerator, hold the steering steady and straight, and let speed fall gradually without hard braking
Why
Hard braking and sharp counter-steering feed energy into the swing and can trigger a rollover or jackknife. Reducing speed smoothly while holding a straight course lets the sway die out.
