To address the question of safety concerning a curve in driving, let's analyze each option step by step:
1. Decelerate before the curve:
- When approaching a curve, reducing speed before entering the curve allows for better control of the vehicle. This ensures that the car can maintain traction and stability, reducing the risk of skidding or sliding off the road. It is generally recommended to slow down to a safe speed before entering the curve to navigate it safely.
2. Accelerate before entering the curve:
- Accelerating before entering a curve is not advisable as it increases the vehicle's speed, making it more difficult to control. High speed through a curve can lead to loss of traction and potential accidents.
3. Apply the brake only after exiting the curve:
- Applying brakes after the curve means that the vehicle would have to navigate the curve without decelerating, which could be dangerous at high speeds. Attempting to slow down only after exiting the curve doesn't address the need for safe handling while within the curve.
4. Apply the accelerator throughout the entire curve:
- Applying the accelerator throughout the curve could lead to increased speed and loss of control, especially if traction is reduced. This practice is generally unsafe for maintaining control through a curve.
Considering all the options, the safest approach is to decelerate before the curve. This allows for better control and stability as the vehicle enters and navigates through the curve.
Therefore, for safety concerning a curve, you should:
- Decelerate before the curve
So, the correct answer is:
- Decelerate before the curve
