If your vehicle starts to skid, you should:

When a vehicle skids, the proper response is to ease off the accelerator and steer in the direction you want the front of the vehicle to go ('steer into the skid'). Avoid braking, which often makes the skid worse, especially on slippery surfaces; if you must brake, do so gently. Sharp counter-steering creates oscillation that can cause a worse skid in the opposite direction. The goal is to restore traction by removing the input that caused the skid (typically too much speed for the surface) and to use the steering to guide the front wheels back into alignment with vehicle motion. Modern vehicles with electronic stability control will automatically help by selectively braking individual wheels — your job is to steer correctly and not panic.
