What rule must you follow when approaching an intersection before making a move?

The left-right-left rule is an essential guideline to follow when approaching an intersection. This method emphasizes the importance of ensuring that it's safe to proceed by checking for traffic coming from all directions. By looking to the left first, you check for any vehicles, bicycles, or pedestrians that may be approaching from that side, as they are typically the closest to you. Then, looking to the right allows you to see if any oncoming traffic or cyclists could be a risk. Finally, a second glance to the left helps confirm that the path is clear before you proceed into the intersection. This thorough checking process significantly enhances safety, ensuring that you are aware of any potential hazards before making a move.

The other options do not encompass the thoroughness of safety checks required when approaching intersections. For example, yielding to oncoming traffic is crucial, but it doesn’t cover the need for a complete visual check. Stopping and looking twice is important, but the specific left-right-left sequence is a structured approach that maximizes awareness of surroundings. Checking mirrors alone is insufficient, as it does not provide a full understanding of what might be occurring directly in front or to the sides of the vehicle.
