What should a driver do if they experience a flat tire?

Engaging the parking brake is a crucial step when experiencing a flat tire, as it helps to stabilize the vehicle and prevent it from rolling or shifting unexpectedly. This is especially important if the vehicle is on an incline or slope, where the lack of a stable position could lead to further danger.

When a driver realizes they have a flat tire, maintaining control of the vehicle is essential for safe handling. Engaging the parking brake not only secures the vehicle but also helps the driver remain focused on finding a safe place to pull over and assess the situation. This action allows them to prepare for changing the tire or seeking assistance without the worry of the vehicle moving.

The other choices suggest actions that could lead to increased danger or loss of control. For instance, accelerating to maintain speed with a flat tire could make it harder to control the vehicle and may worsen the tire damage. Turning off the engine immediately can lead to a loss of power steering, making it even harder to steer effectively. Ignoring the flat tire until reaching the destination not only jeopardizes the safety of the driver but also of others on the road, as driving on a flat tire can cause significant damage to the vehicle and increase the risk of accidents.
