What action should you take if you are approaching a sharp curve in the road?

When approaching a sharp curve in the road, it's crucial to begin braking before entering the curve. This action allows you to reduce your speed to a safe level suited for navigating the curve. Approaching a curve too quickly can lead to loss of control of the vehicle, increasing the risk of skidding or rolling over, especially if road conditions are less than ideal. By slowing down in advance, you can take the curve safely and maintain better control of your vehicle throughout the turn.

Maintaining speed or speeding up while approaching the curve can lead to adverse outcomes, such as losing traction or not being able to complete the turn properly. Additionally, performing a U-turn is inappropriate and dangerous in this context, as it does not properly address the need to navigate the curve safely.
