Council on Law Enforcement Education and Training (CLEET) Law Enforcement Driver Practice Test

How should a driver respond when approaching an increasing radius corner?

1. Prepare to brake

2. Prepare to accelerate

3. Maintain speed

4. Make a sharp turn

The correct answer is: Prepare to accelerate

When approaching an increasing radius corner, the most effective response is to prepare to accelerate. An increasing radius corner is one where the curvature of the turn widens as you progress through it. This characteristic often provides the opportunity for the driver to safely increase speed as they navigate the turn. By preparing to accelerate, you are positioning yourself to make the best use of the corner's geometry. Initially slowing down may be necessary as you enter the corner, but as the radius increases, you can smoothly apply the throttle to maintain control and exit the turn effectively. This not only enhances stability but also allows for a better line through the corner, which is crucial for maintaining momentum, especially in a law enforcement context where agility can be vital. Maintaining speed throughout the turn might not allow for adjustments needed if the corner widens significantly, while making a sharp turn is inappropriate for this type of corner, as it could lead to loss of control. In summary, preparing to accelerate is the correct response for effectively handling an increasing radius corner, optimizing both safety and vehicle performance.
