After signaling and completing a lane change, checking your mirrors is essential for ensuring that it is safe to remain in your new lane and that no vehicles are too close behind you. This action helps you confirm that there is sufficient space between your vehicle and others, reducing the risk of potential collisions. Additionally, checking mirrors after a lane change allows you to stay aware of any changing traffic conditions, including vehicles that may be entering your lane or approaching rapidly from behind.

Speeding up, turning on hazard lights, or slowing down do not provide the same level of safety and situational awareness. While adjusting your speed may be necessary based on traffic conditions, the priority immediately after changing lanes is to ensure that you made the maneuver safely and are aware of your surroundings. Thus, checking mirrors is the most responsible course of action.
