Yes, lane splitting is legal in Minnesota but only under specific conditions. As of July 1, 2025, Minnesota Statute 169.974 permits motorcyclists to pass vehicles within the same traffic lane. The change came from the Minnesota Legislature, and it rewrote decades of traffic law in a single amendment.
Under MN Statute 169.974, a motorcyclist may pass another vehicle in the same lane if they’re traveling at no more than 25 miles per hour and no more than 15 miles per hour faster than the surrounding traffic. Once traffic speeds back up past that threshold, the rider has to merge back into a single lane like everyone else.
The law also draws hard lines around where lane splitting is allowed in Minnesota. According to guidance from the Minnesota Office of Traffic Safety, lane splitting and filtering cannot happen in roundabouts, school zones, active work zones, or on freeway on-ramps where vehicles are queued. These restrictions exist because visibility and reaction time are different in these tighter environments.
None of this changes the fact that motorcycle accidents remain some of the most severe crashes that can happen on Minnesota roads. Even a minor miscalculation at low speed can lead to catastrophic injury. If you or someone you love has been hurt in a crash involving a motorcycle, it’s important to understand how this new law may apply to your case.
What Is Lane Splitting vs. Lane Filtering?
The law treats these two maneuvers differently. The distinction comes down to one main thing: whether traffic is moving.
Lane Splitting
Lane splitting happens when traffic is still moving. A motorcyclist passes a vehicle within the same lane while both are traveling forward, just at different speeds. This is only legal within the speed limit parameters bolded above.
Lane Filtering
Lane filtering happens when traffic has stopped entirely, like at red lights or in stop-and-go congestion. The motorcyclist moves between stopped vehicles to reach the front of the line, staying at or below 15 miles per hour.
Motorcyclists or Motorists: Who’s at Fault in a Lane Splitting Accident?
This is the question that matters most after a crash, and the answer isn’t always straightforward.
Driver Responsibility
Most lane splitting and filtering crashes don’t happen because a driver deliberately blocked a rider. They happen because a driver simply didn’t look.
Before changing lanes or merging, drivers are required to check mirrors and blind spots and signal their intent. That duty doesn’t go away just because lane splitting is legal in Minnesota. A driver who drifts into a rider’s path while switching lanes can be found negligent under ordinary traffic law, separate from the intentional obstruction protections in MN Statute 169.18.
That statute adds another layer on top of this. Under MN Statute 169.18, drivers cannot intentionally impede or attempt to prevent a motorcyclist from lane splitting or filtering when the rider is doing so within the conditions set by 169.974. A driver who drifts toward a rider to close the gap, or who speeds up specifically to prevent a pass, may be found at fault even though the motorcyclist was the one moving between lanes.
Motorcyclist Responsibility
Motorcyclists carry real responsibility under this law. They’re the ones who have to judge, in real time, whether a lane split or filter is actually safe. That means staying within the speed thresholds and steering clear of the areas where the maneuver is banned outright, including school zones, work zones, highway on-ramps, and roundabouts. A rider who blows past 25 mph while splitting, or who tries to filter through a roundabout, is no longer operating within what the statute allows, and that can weigh against them in the case of a crash.
Fault in these cases often depends on the details: exact speeds, lane positioning, dash cam or traffic camera footage, witness accounts, and the like. It’s all the evidence an insurance company will try to spin in its favor, which means it’s also the exact information a skilled attorney knows how to secure and use.
