Minnesota To Allow Lane Filtering

The AMA endorses lane filtering.

With the signing of HF 5247 into law by Governor Tim Walz on Friday, May 24, Minnesota has become the sixth state to legalize lane filtering. This move places Minnesota as the easternmost state to adopt this legislation, joining California, Utah, Montana, Arizona, and Colorado in allowing motorcyclists to filter through traffic.


Lane filtering permits motorcyclists to navigate through slow-moving or stationary traffic at intersections and stoplights, a practice expected to enhance rider safety. Nick Sands, AMA Central States Representative, highlighted the safety benefits for riders on Minnesota’s roads, emphasizing the positive momentum for lane-filtering legislation following similar successes in Colorado.


The new law, part of a supplemental budget bill affecting various departments, including the Minnesota Department of Transportation, stipulates that motorcyclists can filter through traffic at speeds not exceeding 25 miles per hour and no more than 15 miles per hour over the speed of the surrounding traffic. Authored by Sen. Scott Dibble and Reps. Frank Hornstein, Brad Tabke, and Erin Koegel, this provision will take effect on July 1, 2025.

Minnesota becomes the sixth state to legalize lane filtering.


The push for this legislation gained traction after AMA member and BMW MOA Treasurer Phil Stalboerger shared his personal experience of being rear-ended while riding his motorcycle. His advocacy, combined with support from the motorcycle community, clubs, and small businesses, played a significant role in the bill's passage. Stalboerger noted the rewarding outcome of grassroots efforts in promoting rider safety.


Additionally, HF 5247 includes measures to penalize drivers who deliberately impede motorcyclists, reinforcing that operators of motor vehicles must not intentionally obstruct motorcycles when lane filtering.


The AMA supports the legalization of lane filtering, citing its documented success in other states and various studies that demonstrate its effectiveness in improving motorcycle safety. More information on the AMA’s stance on lane filtering and lane splitting can be found on their website.

    As a rider that doesn't live in an area that has either splitting or filtering I don't understand how this contributes to safety when you put your fate/safety in the hands of car drivers. When I visit California in my car, I am unclear of what my responsibility as a car driver is ie. If I shift over a foot in my lane to miss a pot hole and I hit a motorcyclist passing me in my lane who is at fault? Apparently a motorcyclist can change into my lane and expect me to accommodate them, but as a driver can I do the same to a biker? Seems to me it is an accident waiting to happen and really only benefits the lawyers.

      I would have agreed with you before experiencing how lane splitting works on the road. I'm in a state that doesn't allow lane splitting, but put about 6k miles in CA years back. Lane splitting was a huge improvement in getting thru traffic, and I don't recall any 'close calls' in those miles. (Obviously not all lane splitting, but I was in locked up traffic many, many times. Sometimes for 15-20 miles)... I'm SURE there were a couple, but I was pretty conservative and defensive, so I think that largely mitigated potential issues. Getting thru the stop & go sooner not only reduced the traffic delay, but also felt significantly safer. If you are in solid traffic, you have less maneuvering room if someone behind you isn't paying attention, and you need to be constantly watching 360 degrees for danger. If you are moving thru stalled traffic, the main watch zone get's narrowed to about the 90 degrees (45 to left, 45 to right) ahead of you. Here's my observations: 1) The key pieces to safe lane splitting is using good judgement as a rider, and riding accordingly. Following the not more than 15 over surrounding traffic or over 25mph is about what I found to be a natural 'comfort zone'. Usually, I'd ride between the left two lanes to reduce being near on and off ramp merging. If the traffic situation is shifting, or there's a tight lane due to oversized vehicles, extended mirrors, or someone crowding a line, the rider can ALWAYS slow down to maneuver, or get back in a lane, or cross thru a lane to a different split. If traffic is stopped bumper to bumper, no one is coming into your lane without some warning, and as a rider, you should be watching the front wheels of cars for an indication that someone might be doing that. For reference, 15 mph is about the pace of a elite marathoner. If things felt tight, I might only be moving 5-10 mph. Once traffic starts moving, it wasn't a problem to blend back into a lane. 2) If lane splitting is default, cars DO start checking their mirrors before crossing over. Frankly, most drivers (and riders, too) should be checking their mirrors more often. In some ways, I think this ALSO made drivers more aware of motorcycles in general. Can't prove it, and it could be that there seemed to be more motorcycles in general. But regardless, if I was in doubt, I just slowed down. Defensive riding and paying sharp attention should be your default mode when you are out there. 3) Some riders are splitting MUCH faster than that, and IMO are an accident waiting to happen. But that's also true w/o lane splitting with the aggressive riders who are weaving back and forth thru traffic. For the most part, I think splitting was a big improvement in safe riding. There are legal battles and too many accidents. Large numbers are at intersections, or being run over by someone who didn't see you. The splitting law clearly regulates rules for the other vehicles.

    I understand the benefits of lane splitting at lower speeds but what I saw in California was Bikes going by me while I'm doing 65 mph on I10 or the 405.. To me that is just nuts. I have talked to highway patrol about this and they say it is just a judgement call versus a definitive speed above which they will have a "conversation". Since I usually have a rental I am paranoid about lane splitters for fear of scratching the car. As a biker I would never take those risks at that speed.
