Which action should you avoid when passing another vehicle?

When passing another vehicle, it's essential to get back into your lane only when it is safe to do so. Specifically, you should wait until you can see the full front end of the vehicle you have passed in your rearview mirror before returning to your lane. This action ensures that you provide sufficient distance and safety margin between your vehicle and the one you have just passed, reducing the risk of a collision caused by insufficient space.

While maneuvering back into your lane too soon might feel instinctive, it can lead to dangerous situations, such as cutting off the other driver or miscalculating the distance and speed at which you're traveling. The key principle here is to prioritize safety and awareness of your surroundings when changing lanes on the road.
