What must you do when passing another vehicle?

When passing another vehicle, it is essential to check traffic ahead of you to ensure that the lane you wish to move into is clear and that you have enough space to safely complete the maneuver. This step not only enhances your safety but also that of the drivers around you. Observing the road ahead helps you assess the speed of opposing traffic and anticipate any potential hazards, such as oncoming vehicles or obstacles in your path.

This careful attention plays a vital role in facilitating a smooth and safe passing process. It allows you to make informed decisions about when and how to execute the pass, reducing the risk of accidents as you change lanes to overtake another vehicle. Other options, like accelerating aggressively or changing lanes without signaling, can lead to dangerous situations by compromising safety and communication with other road users. Similarly, only looking in the rearview mirror fails to provide the necessary awareness of what is ahead.
