Final answer:
To regain control in a fish-tail skid, the driver should steer in the direction of the skid.
Step-by-step explanation:
In a fish-tail skid, the rear end of the vehicle starts to slide back and forth, causing the vehicle to lose control. To regain control, the driver should steer in the direction of the skid. This means turning the steering wheel in the same direction that the rear of the vehicle is sliding.
Steering in the opposite direction of the skid (option 2) can actually worsen the skid and make it harder to regain control. Applying the brakes too firmly (option 3) can cause the vehicle to skid even more. Accelerating rapidly (option 4) can also make the skid worse.
