If a tire blows out, you should put the brakes on hard to stop quickly. What is the correct response?

  1. True

  2. False

  3. Only if it is safe to do so

  4. Depends on the speed of the vehicle

The correct answer is: False

When a tire blows out while driving, applying the brakes hard to stop quickly is not the recommended response. Instead, the correct action is to maintain control of the vehicle while safely bringing it to a stop if necessary. When a tire blows out, the immediate reaction to brake hard can cause loss of steering control or make the situation more dangerous, especially if it is a front tire that has blown out. In the event of a blowout, it's important to keep both hands on the steering wheel and allow the vehicle to slow down gradually while steering straight. Once the vehicle is under control and has come to a safe stop, the driver can assess the situation and decide on the next steps, such as changing the tire or calling for assistance. The focus should be on handling the vehicle safely rather than making a quick stop.
