Final answer:
The correct option is B. Release the service brakes. To stop a trailer skid, you should release the service brakes to allow the wheels to regain traction. Avoid using the trailer hand brakes or counter-steering, as these actions may worsen the skid.
Step-by-step explanation:
To stop a trailer skid, one should generally release the service brakes. Applying the trailer hand brakes or counter-steering could potentially worsen the skid. The key is to regain traction and stability, and by releasing the brakes, you allow the wheels to roll freely and regain their grip on the road. It is important to remain calm and make smooth, gradual movements to correct the skid.
To stop a trailer skid, you should counter-steer. When a trailer starts to skid, it means that the wheels are sliding and losing traction. By counter-steering, you turn the steering wheel in the direction of the skid to regain control. This helps align the tires with the direction of travel and allows you to regain control of the trailer.
