When a tire suddenly goes flat while driving, the best action to take is to hold the steering wheel tightly and keep the vehicle straight. This is crucial because a sudden flat tire can cause the vehicle to pull to one side, making it challenging to control. By maintaining a firm grip on the steering wheel and focusing on keeping the vehicle heading straight, you can avoid losing control and potentially swerving into other lanes or off the road.

Being calm and steady is essential in this situation. Once the vehicle is under control, the driver can then slowly reduce speed and find a safe place to pull over. This approach minimizes the risk of an accident and allows for a safer response to the flat tire.

Accelerating to regain control is risky, as it can increase difficulty in managing the vehicle. Braking hard can lead to loss of control, especially if the flat tire affects the stability of the car. Steering off the road might be necessary, but it should only be done once control is established and a safe location is identified. Thus, keeping the vehicle straight while holding the steering wheel firmly is the most responsible and effective initial response to a flat tire.
