Which type of skid occurs when the vehicle's direction remains straight while one or more brakes lock up?

The choice of a braking skid is accurate because this type of skid is characterized by a loss of traction in which the vehicle continues in a straight line despite the driver applying the brakes. When one or more wheels lock up during braking, the vehicle can slide straight ahead instead of following the intended path. This is often caused by excessive braking force exceeding the tire's traction capabilities on the surface, which can lead to a loss of control.

In contrast, other types of skids involve different mechanics: an acceleration skid typically occurs when the driver accelerates too quickly, resulting in the wheels spinning and losing grip, particularly in rear-wheel-drive vehicles. A cornering skid, on the other hand, happens during turns when the vehicle exceeds its cornering limits, causing the vehicle to slide sideways. Skid steer is not a recognized term in the context of skids in emergency vehicle operations. Thus, understanding the braking skid helps in recognizing how to respond to maintaining vehicle control during emergency situations effectively.
