Are retarders effective in preventing skidding on slippery roads?

Retarders can indeed increase skidding on slippery roads. While they are designed to help slow down a vehicle, using them on wet or icy surfaces can disrupt traction and lead to loss of control. Instead of helping the tires maintain their grip on the pavement, retarders can cause the wheels to lock up or skid because they apply braking force that can exceed the friction available between the tires and the road. Proper driving technique on slippery surfaces typically involves more gradual braking methods and maintaining a steady speed to avoid sudden changes that could lead to skidding. Understanding the limitations of retarders in adverse weather conditions is crucial for safe vehicle operation.
