Final answer:
If your vehicle's wheel drifts onto the shoulder, calmly reduce your speed and lightly steer to return the car to the road, avoiding sudden movements or oversteering.
Step-by-step explanation:
If your vehicle's wheel drifts onto the shoulder of the road, it is important to remain calm and avoid overreacting. You should gently reduce your speed and steer lightly to return the car to its original position on the road. It's critical not to make any sudden movements or to oversteer, as these actions could cause you to lose control of your vehicle. Instead, smoothly steer back onto the road when it's safe to do so, and then proceed at a safe speed, staying mindful of your surroundings and road conditions.
