Which action is recommended to manage space while driving a large vehicle?

Maintaining a safe following distance is crucial when driving a large vehicle for several reasons. Large vehicles, such as trucks, require a longer stopping distance due to their size and weight. By keeping an appropriate distance from the vehicle in front, a driver has ample time to react to sudden stops or emergencies, reducing the likelihood of collisions.

Additionally, a safe following distance allows for better visibility of the road ahead, which is especially important in larger vehicles where visibility can be naturally limited. It gives the driver the opportunity to anticipate and respond to traffic conditions, obstacles, and changes in the road.

This practice also contributes to overall road safety, as it helps prevent rear-end accidents, which are more common with larger trucks due to their momentum and braking power. The driver can maintain better control of the vehicle while providing sufficient space to navigate safely.

The other options, such as driving closely behind other vehicles, changing lanes frequently, and only using mirrors for distance estimation, do not promote safe driving practices and can increase the risk of accidents. Maintaining a safe following distance is a fundamental aspect of defensive driving, particularly for large vehicle operators.
