What should you avoid when passing another vehicle?

When passing another vehicle, changing lanes immediately can be dangerous. It's crucial to ensure that the lane is clear before making the move, which means you should check your mirrors and possibly glance over your shoulder to confirm that no other vehicles are in your blind spot. Making a sudden lane change can result in collisions, especially if the vehicle you are passing or other drivers are not expecting such an action. A safer practice involves signaling your intention to change lanes well in advance and ensuring a safe distance between your vehicle and others. This careful and methodical approach allows for better communication with other drivers and helps prevent accidents.

The other options represent necessary practices while passing: looking for other vehicles ensures you are aware of your surroundings, maintaining speed helps you complete the maneuver efficiently, and signaling communicates your intentions to others on the road.
