Montana Commercial Drivers License (CDL) Practice Test

Braking during a curve can destabilize a vehicle and increase the risk of losing control. When a driver brakes while turning, it shifts weight towards the front tires, reducing rear tire traction. This can lead to oversteering, where the rear of the vehicle swings out, or understeering, where the vehicle fails to turn as intended.

Instead, it is advisable to adjust your speed before entering the curve. By slowing down beforehand, you can maintain better control through the turn, ensuring that you can navigate safely and effectively. Exiting the curve may also require minimal adjustments to speed, but braking at this point is generally not necessary unless conditions dictate otherwise.

Maintaining a steady speed through a turn is crucial for stability, which is why it's best to refrain from braking during this phase of the maneuver.
