What is lane filtering?
Lane filtering is riding a motorcycle between lanes or rows of slow-moving or stopped traffic going in the same direction.
Is that the same as lane splitting?
No. Lane splitting allows motorcyclists to ride between lanes of traffic at any speed. Lane filtering only allows it at low speeds or in stopped traffic. Is it legal in Minnesota? Starting July 1, 2025, it will be.
Why was this law passed?
Safety. Motorcycles can be harder to see than cars and trucks, making them more vulnerable in mixed traffic. Lane filtering lets riders get out of the way.
Is it really safer?
Yes. According to a study published by the University of California–Berkeley, it can help motorcyclists get out of dangerous situations. It also helps them avoid overheating.
How fast can riders go?
The new law allows motorcyclists to filter through traffic “at not more than 25 miles per hour AND no more than 15 miles per hour over the speed of traffic.”
Does it help reduce traffic?
Probably. The Oregon Department of Transportation has said “Allowing motorcycles to move more freely through traffic could help reduce overall congestion, and potentially reduce some types of motorcycle crashes.”
How is this fair?
Most motorcycles accelerate faster than cars and trucks. When they go first, car and truck drivers have less traffic—which means they can get going sooner, too.
What if I don’t like this law?
If you’re a motorcyclist, you can choose not to filter lanes. If you’re a car or truck driver, remember it’s legal. Deliberately preventing someone from lane filtering is a misdemeanor.
What do car and truck drivers need to know?
This will change what happens when traffic is slow or stopped. Always:
- Check your mirrors and blind spots before changing lanes or turning
- Use your turn signals to note your intentions before changing lanes
- Leave at least 3 to 4 seconds of following distance behind a motorcyclist
What do motorcyclists need to know?
- Don’t go more than 15 mph faster than traffic flow or more than 25 mph total.
- Don’t pass on the shoulder—only between two lanes going the same direction.
- Don’t split if you might not fit. No one is obligated to make room for you.
- Follow the law. Be reasonable, responsible, respectful, and aware of conditions.

Am I expected to say “ope” or “excuse me” as I’m lane filtering?
Ummm ya, you betcha! After all, this IS Minnesota, right?
