In the event of a flat tire or blow-out, what is the first action you should take?

When experiencing a flat tire or blow-out, the most critical initial action is to hold the steering wheel firmly. This is essential because a sudden loss of tire pressure can cause the vehicle to sway or lose control. By maintaining a strong grip on the steering wheel, the driver can steer the vehicle more effectively and stabilize it, preventing it from veering off course or into traffic.

It's also important to note that braking hard is not advisable in this situation, as it can cause the vehicle to skid or worsen the loss of control. Checking mirrors can be helpful, but it comes after stabilizing the vehicle, as does turning on hazard lights, which is done to alert other drivers after the immediate situation is under control. Therefore, holding the steering wheel firmly is the appropriate first step to ensure safety when facing such an emergency.
