How should you handle a flat tire?

Answer: A — Get out of the vehicle and inspect the tire

When encountering a flat tire, it is important to handle the situation carefully. Option B, exiting the vehicle and waiting for help, may not be the best course of action as it leaves you vulnerable on the side of the road. Option C, keep driving and speed up, is not a safe or responsible choice as it can cause further damage to the tire and potentially put you and others in danger. Option D, jiggling the steering wheel, is an incorrect method for fixing a flat tire and could result in losing control of the vehicle. Therefore, the best course of action in this situation is to follow option A, getting out of the vehicle and inspecting the tire to determine the best course of action for repairing or replacing the tire.
