What should you do if the rear wheels slip during acceleration?

Letting off the throttle is the correct response when the rear wheels slip during acceleration. This action helps to reduce the power being sent to the wheels, which can allow them to regain traction on the road surface. When the wheels encounter a slippery condition, such as ice or wet pavement, reducing power can help stabilize the vehicle and correct the slide.

Maintaining or increasing acceleration can exacerbate the loss of traction, causing the vehicle to skid further. Stepping sharply on the brakes can lead to loss of control, as it might cause the rear wheels to lock up and increase the risk of a spin. Steering sharply may also not be effective and can result in oversteering, further jeopardizing control over the vehicle. Thus, the best course of action is to ease off the throttle to safely regain traction and stabilize the vehicle.
