What should you check before passing another vehicle?

Before passing another vehicle, it is essential to check your rearview mirror and blind spots. This step is crucial for ensuring that the lane beside you is clear and safe for a maneuver. The rearview mirror provides a view of traffic approaching from behind, which helps you determine if it's safe to change lanes. Additionally, blind spots are areas not visible in your mirrors; therefore, checking these areas directly is vital to ensure no vehicles are present before you move over. Taking these precautions helps prevent collisions and promotes safer driving practices.

While aspects like checking your speedometer and gas gauge, your turn signals and headlights, or ensuring your seatbelt and mirrors are in place are important for overall safe driving, they do not specifically pertain to the critical moment of passing another vehicle.
