Braking before entering a turn is essential for maintaining control and stability while navigating a curve. This practice allows the driver to reduce speed to an appropriate level for the turn, which helps prevent skidding or losing traction with the road. By slowing down before the turn, drivers can better manage the dynamics of their vehicle and react more effectively to any unexpected obstacles that may arise during the turn. Applying brakes during a turn can shift the weight of the vehicle and may lead to a loss of steering control, particularly in larger vehicles. Once a vehicle enters a curve at an inappropriate speed and begins braking during the turn, it can potentially cause the vehicle to tip or roll over. It's important to approach the turn at a safe speed, apply the necessary braking beforehand, and then steer through the turn smoothly. After making the turn is typically too late to adjust speed effectively, as the vehicle will already be committed to the path of the turn. Therefore, reducing speed and applying brakes in advance of the turn is the safest and most effective strategy for successful maneuvering.
