CDL General Knowledge TestDriving SafelyMedium
You are driving a commercial vehicle on a two-lane road and are approaching a curve. To maintain control and safely navigate the curve, when should you apply your brakes?
- AAfter entering the curve, gradually releasing them as you exit.
- BBefore entering the curve, and then accelerate gently through it.
- COnly if you feel the vehicle starting to lose traction in the curve.
- DWhile in the curve, as needed to reduce speed.
Show answer & explanationAnswer & explanation
Correct answer: B. Before entering the curve, and then accelerate gently through it.
To safely navigate a curve, you should reduce your speed by braking before entering the curve. This allows you to maintain a safe speed and gently accelerate through the curve, maintaining vehicle stability and control.
Why the other options are wrong
- A. Applying brakes after entering the curve can shift weight and reduce traction, leading to instability.
- C. Waiting until you lose traction is a reactive and dangerous approach that often leads to accidents.
- D. Braking sharply in a curve can cause a skid or loss of control, especially in a heavy vehicle.
Safe Curve Negotiation
The technique of reducing speed before entering a curve and maintaining a controlled speed or gentle acceleration through it to prevent loss of traction.
- Brake before the curve
- Maintain steady speed in curve
- Avoid braking in the curve
Memory trick: Slow Before, Smooth Through, Safe You.
