What should you do if your vehicle begins to skid?

When your vehicle begins to skid, the appropriate action is to steer into the direction of the skid. This technique is known as "countersteering" and helps to regain control of the vehicle. When the rear wheels lose traction, steering in the direction you want the front wheels to go helps to align the vehicle’s tires with the intended path. This action can prevent the vehicle from spinning out and allows you to regain control as traction is restored.

The other options do not effectively address the situation. For instance, applying the brakes firmly can exacerbate the skid by shifting weight and causing further loss of traction. Turning off the engine is unnecessary and may not provide any benefit; it can also cause a loss of steering control if power steering is disabled. Accelerating might seem intuitive to regain control, but it actually increases the likelihood of losing further traction and worsening the skid.
