What action is required when you intend to change lanes?

When changing lanes, it's essential to signal your intention to alert other road users, which is a fundamental part of safe driving practices. Giving a signal indicates to other drivers that you plan to make a maneuver, allowing them to adjust their speed or position accordingly.

Following the signal, checking for traffic ensures that it's safe to change lanes. This step involves looking in both the side mirrors and checking your blind spots to ensure that no vehicles are approaching or are already in the lane you intend to occupy. Only after confirming that it is safe to proceed should you change lanes.

This method promotes safety on the road by reducing the risk of accidents and ensuring that drivers around you are aware of your actions. The other options do not encompass the complete and safe process required for changing lanes, which includes signaling and careful checking of traffic conditions before making the maneuver.
