Correct Lane Choice on Multi-Lane Highways

Goal: Separate traffic from slowest to fastest (right to left). It is foolish to think that all vehicles, with their varying characteristics, can, will and should drive at the exact same speed. We want to allow variations in speed while minimizing conflicts.

Method: 1. Make sure your eyes never fixate on the vehicle in front of you. Scan ahead, and check the center rearview mirror (if equipped). Checking behind every 5-8 seconds gives an understanding of what others are doing behind you. Read the highway much like you read a chess board, understanding how the pieces (vehicles) move.

  1. The default lane is the RIGHT HAND LANE. When the road is empty, stay in the right-most non-exit only lane. Doing so gives you an escape route (the shoulder), reduces the risk of you being rear-ended by emergency vehicles from behind, and reduces workload as you are not having to watch for traffic zooming past on both sides.

  2. Change lanes to the left when you have a REASON to do so. Reasons include: passing (overtaking) a vehicle in front of you, allowing merging traffic space to enter the freeway, giving space to a disabled vehicle on the shoulder (move over law), to prepare for a left turn / left exit, or emergency situations (say an object on the road). DO NOT MERGE directly into any lane other than the right-hand most. Establish yourself in the right-most lane for at least 10 seconds before trying to move left.

  3. Change lanes to the right whenever you are ABLE TO and no longer have a reason to stay left. If the right hand lane is clear, take the lane as to free up space for other traffic to move past you on the left. Avoid the right-most lane ONLY when there is heavy merging traffic -- once this is past, move back to the right lane if not passing. If you see slower traffic in the right lane that you will be moving past, it is not necessary to move from a middle lane to the right only to change back left 10 seconds later. Remember that it is possible to be CONTINUOUSLY passing slower traffic -- in this case, continue using the lane you are in, then move right when done.

  4. If traffic is passing you on the right, CONSIDER that you may be in the WRONG lane. Examine your surroundings and, instead of being an impediment to traffic flow in the middle or left, move right.

  5. DO NOT TAILGATE. Just because somebody is causing traffic problems and safety issues does not give you the excuse to follow suit. Alternative ways to get people to move right include flashing of high beams and signaling left in the left-most lane.

Rural 3 and 4 lane freeways are becoming more common in response to heavier inter-city traffic, and poor lane discipline is becoming a serious issue that is causing aggressive driving and reducing the capacity of roadways built by taxpayer $$$s. The idea that the right lane is for "entering and exiting only," and that everyone should sit in the 2nd from left lane to access the "passing lane" needs to stop. Once we get good at lane discipline, then our freeway networks will catch up to our OECD peers in safety.
