When changing lanes on a multilane road, which lane should you check in addition to the one next to you?

When changing lanes on a multilane road, it’s essential to check the far lane in addition to the lane directly next to you. This practice is crucial for ensuring a safe lane change, as vehicles can be present in the further lane and may be moving faster than those in the adjacent lane. By scanning the far lane, you are more aware of the overall traffic conditions and can make a more informed decision about when it's safe to change lanes.

Additionally, monitoring the far lane can help you anticipate potential hazards, such as a vehicle merging into your intended lane from a distance, which is especially important at higher speeds. This approach promotes a more comprehensive situational awareness, ultimately leading to safer driving practices on multilane roads.
