Arkansas Commercial Driver License (CDL) Practice Test

Applying brakes sharply when driving into a curve is not advisable because doing so can upset the vehicle's balance and traction. When a driver brakes suddenly while in a curve, it can lead to a loss of control, risking skidding or rolling over, especially in larger vehicles like trucks. Instead, it's crucial to slow down before entering the curve and to maintain a steady speed throughout the turn. This approach helps in maintaining the proper distribution of weight on the tires and allows for better control of the vehicle while navigating the turn.

In contrast, being in a gear that allows slight acceleration can help in maintaining traction and control while going through the curve. Adhering to the posted speed limit ensures safety and compliance with road regulations, while reducing speed before entering a curve allows the driver to navigate safely without abrupt maneuvers that could compromise stability.
