What should a driver do if a tire blows out while driving?

Answer: A — Pull the vehicle off to the side of the road

If a tire blows out while driving, it is important to remain calm and steer the vehicle to the side of the road. Option B, shifting to a lower gear, would not effectively address the risk of losing control of the car. Option C, speeding up, would only increase the danger and make it more difficult to safely pull over. Option D, stopping abruptly, could cause the car to swerve and potentially cause an accident. The best course of action is to slowly and safely pull over to the side of the road before assessing and addressing the blown tire.
