What changed

As of September 14, 2026, lane splitting on a motorcycle in Arizona is no longer just a traffic ticket. It is now reckless driving, a criminal charge.

Weaving between moving cars was already against the rules in Arizona. The new law, House Bill 2941, raises the stakes. A rider caught doing it can now face a criminal record, possible jail time, and a suspended license.

The good news: lane filtering, which Arizona made legal in 2022, is still allowed. The trick is knowing the difference.

Splitting vs. filtering: the simple version

Lane splitting means riding between lanes while traffic is moving. Think of a bike zipping down the lane line on a busy road at 40 mph. That is now reckless driving.

Lane filtering means easing between cars that are stopped, like at a red light. It lets riders get out of the spot where they are most likely to be rear-ended. That is still legal, but only when every condition below is met:

Traffic in your direction is fully stopped.
The speed limit is 45 mph or lower.
There are at least two lanes going your direction.
You ride no faster than 15 mph.
You are on a two-wheeled motorcycle.
It is safe to do so.

Miss even one of these and a legal filter can turn into an illegal split.

Quick-look chart: is this legal?

Situation	Legal?	Why
Easing between cars stopped at a red light on a 35 mph street, going 10 mph	Yes	Meets every filtering rule
Riding between moving cars on any road	No	That is lane splitting, now reckless driving
Filtering between stopped cars on the freeway	No	Freeway speed limits are over 45 mph
Filtering at a red light, but going 25 mph	No	Over the 15 mph cap
Passing a car inside its own lane	No	Now counts as reckless driving too
Filtering on a one-lane road	No	Needs two or more lanes going your way
Riding two side by side in one lane	Yes	Allowed, but never more than two

What it can cost you

A first offense is a misdemeanor. A second one within two years brings mandatory jail time.

	First offense	Second offense within 24 months
Charge	Class 2 misdemeanor	Class 1 misdemeanor
Jail	Up to 4 months	At least 20 days, up to 6 months
Fine	Up to $750, plus court fees	Up to $2,500, plus court fees
License	Judge may suspend up to 90 days	Suspended for 1 year
Probation instead of jail?	Possible	Not until 20 days are served
Reported to ADOT?	Yes	Yes

A reckless driving conviction also stays on your record. It can raise your insurance rates for years.

If you're hurt in a crash

This law can shape what happens after a crash, not just at a traffic stop. If a rider was lane splitting when a crash happened, expect the insurance company to use it to blame the rider.

Drivers have rules too. Arizona law says every motorcycle gets the full use of a lane. A driver who crowds a rider, changes lanes without looking, or opens a door into traffic can still be the one responsible.

If you were legally filtering when you were hit, that matters. Details like the speed limit, whether traffic was stopped, and how fast you were going can make or break your claim. Photos, dashcam or helmet-cam video, and witness names help prove what happened.
