What must you do if you have a flat tire while driving?

Answer: B — Pull over to a safe location and stop

When faced with a flat tire while driving, pulling over to a safe location and stopping is crucial for your safety and the safety of other road users. Continuing to drive on a flat tire can cause further damage to the tire, the wheel, and potentially lead to loss of control of the vehicle, creating a dangerous situation. By stopping in a safe area, you can assess the situation without risking an accident from being in traffic or compromising your safety. Finding a level, well-lit area away from traffic provides you the opportunity to change the tire if you are equipped to do so, or to seek help from roadside assistance if necessary. This approach minimizes hazards and helps ensure that you handle the flat tire situation in a controlled manner.
