Is Lane Splitting Legal in the US? 7 States Where You Can Ride Between Traffic Lane Splitting Laws 

Lane splitting is fully legal in only one U.S. state (California), while six additional states permit limited lane filtering under specific conditions. As of October 2025, the states that allow some form of lane splitting or lane filtering are California, Utah, Arizona, Montana, Colorado, and Minnesota.

Understanding Lane Splitting: What Motorcycle Riders Need to Know

Lane splitting—the practice of riding a motorcycle between lanes of traffic moving in the same direction—remains one of the most debated topics in motorcycle law. For riders seeking to navigate congested highways more efficiently, understanding where this maneuver is legal can mean the difference between a safe commute and a costly traffic citation.

The legal landscape for lane splitting has evolved significantly in recent years. What was once prohibited in nearly every state has gained acceptance in select jurisdictions, with more states considering legislation to permit this practice under controlled conditions.

Where Is Lane Splitting Legal in the United States?

States That Allow Lane Splitting or Lane Filtering

California: Full Lane Splitting Legal

California became the first state to formally legalize lane splitting in 2016 through Assembly Bill 51 (AB-51), which officially defined and authorized the practice. California permits motorcyclists to split lanes at highway speeds, making it the most permissive state for this maneuver.

Key requirements in California:

• Motorcyclists must ride safely and prudently
• Lane splitting should not be performed at excessive speeds
• Riders should consider traffic flow and conditions
• California Highway Patrol recommends traveling no more than 10 mph faster than surrounding traffic

Minnesota: Lane Splitting and Filtering Legal (Newest State)

Minnesota legalized both lane splitting and lane filtering as of July 1, 2025, making it one of the newest states to permit these practices. The state joins California, Utah, Montana, Arizona, and Colorado in allowing these maneuvers.

Minnesota’s restrictions include:

• Speed limitations on when and where lane sharing can be performed
• Specific conditions must be met for legal lane splitting
• Motorcyclists must not exceed 15 mph over the speed of traffic

Utah: Lane Filtering Legal

Utah permits lane filtering rather than full lane splitting. Lane filtering became legal in Utah in 2022, allowing riders to pass between lanes of stopped traffic on roads with speed limits of 45 mph or below.

Utah’s lane filtering requirements:

• Only permitted when traffic is stopped
• Road speed limit must be 45 mph or less
• Motorcyclists cannot exceed 15 mph while filtering
• Filtering is prohibited on freeways

Arizona: Lane Filtering Permitted

Arizona allows limited lane filtering under specific conditions. Motorcyclists can ride between lanes of stopped or slow-moving traffic, but strict parameters apply.

Arizona lane filtering rules:

• Only legal on roads with posted speed limits of 45 mph or less
• Traffic must be moving at 15 mph or slower
• Motorcyclists cannot exceed speeds greater than 15 mph while filtering

Montana: Lane Filtering Allowed

Montana permits lane filtering with similar restrictions to other filtering states. Riders can move between lanes of stopped or slow-moving vehicles under controlled conditions.

Montana’s requirements:

• Traffic must be stopped or moving slowly
• Speed restrictions apply to filtering motorcyclists
• Only allowed in specific traffic conditions

Colorado: Lane Filtering Legal

Colorado has joined the states permitting lane filtering under restricted circumstances. The state allows motorcyclists to navigate between lanes when traffic is congested.

Colorado lane filtering parameters:

• Limited to specific traffic scenarios
• Speed and location restrictions apply
• Designed to improve traffic flow and rider safety

Is Lane Splitting Legal in Alaska?

No, lane splitting is illegal in Alaska. Alaska’s traffic laws grant motorcycles the same full-lane rights as other vehicles and do not authorize riding between lanes. Alaska Administrative Code 02.427 makes lane splitting illegal by prohibiting motorcycles from passing or overtaking vehicles in the same lane or driving between lines or lanes of vehicles or traffic.

Alaska does allow lane sharing, where up to two motorcycles can ride side-by-side in the same lane, but splitting lanes between cars is prohibited.

Is Lane Splitting Legal in Hawaii?

No, traditional lane splitting is not legal in Hawaii. Hawaii maintains a ban on lane splitting in 2025 under HRS 291C-153(c), making the state stricter than California, Utah, Arizona, Montana, Colorado, and Minnesota. While Hawaii allows motorcycles to use the full lane and doesn’t explicitly ban lane filtering, it does not allow motorcycles to move between clearly marked lanes.

However, Hawaii does allow shoulder surfing, where motorcyclists can ride along the shoulder of the road to pass vehicles stopped on the road.

Pending Legislation

Connecticut’s legislature is considering changes in 2025 with Senate Bill 1083, which could potentially legalize some form of lane filtering in the state. Several other states have introduced legislation to study or permit lane splitting, though most bills have not yet passed.

Six states have recently taken steps to adopt motorcycle lane splitting rules, indicating growing momentum for broader acceptance of the practice.

Understanding the Difference: Lane Splitting vs. Lane Filtering

Lane Splitting: The practice of riding a motorcycle between lanes of moving traffic traveling in the same direction. This typically occurs at highway speeds and is legal only in California.

Lane Filtering: A more restricted practice where motorcyclists ride between lanes of stopped or very slow-moving traffic, usually at intersections or in congested conditions. This is permitted in Utah, Arizona, Montana, Colorado, and Minnesota under specific conditions.

Lane Sharing: When two motorcycles ride side-by-side within the same lane. This is legal in most states but is distinct from lane splitting.

Legal Risks and Penalties for Lane Splitting

Penalties in States Where It’s Illegal

Motorcyclists caught lane splitting in states where the practice is prohibited face various penalties:

Traffic Citations:

• Fines typically range from $100 to $500 for first offenses
• Points added to driving record
• Potential increase in insurance premiums

Enhanced Penalties: Some states have passed laws with serious penalties for lane splitting violations, including losing motorcycle endorsements.

Accident Liability: If a lane-splitting motorcyclist is involved in an accident in a state where the practice is illegal, they may be found at fault regardless of other circumstances, which can affect:

• Insurance claims
• Personal injury settlements
• Criminal liability in serious accidents

Legal Defense Considerations

In states where lane splitting is illegal, riders typically cannot use traffic congestion or safety concerns as legal defenses. Courts generally hold that motorcyclists must follow the same lane usage rules as other vehicles.

Safety Considerations for Lane Splitting

When Lane Splitting Is Permitted

Even in states where lane splitting or filtering is legal, riders should prioritize safety:

Speed Management:

• Never exceed recommended speed differentials
• Adjust speed based on traffic flow and density
• Be prepared to stop suddenly

Visibility and Awareness:

• Use headlights at all times
• Wear high-visibility gear
• Watch for vehicles changing lanes
• Anticipate driver blind spots

Road Conditions:

• Avoid lane splitting in poor weather
• Be cautious on wet or slippery surfaces
• Consider road debris between lanes

Traffic Pattern Recognition:

• Identify vehicles likely to change lanes
• Watch turn signals and driver behavior
• Maintain escape routes

Research on Lane Splitting Safety

Studies from California and other jurisdictions suggest that when performed correctly under appropriate conditions, lane splitting may reduce certain types of motorcycle accidents, particularly rear-end collisions. However, the practice requires skill, experience, and constant vigilance from riders.

Frequently Asked Questions About Lane Splitting

Is lane splitting legal in all 50 states?

No, lane splitting is not legal in all 50 states. Only California permits full lane splitting, while Utah, Arizona, Montana, Colorado, and Minnesota allow limited lane filtering under specific conditions. The remaining 44 states prohibit the practice.

What’s the penalty for illegal lane splitting?

Penalties vary by state but typically include fines ranging from $100 to $500, points on your driving record, and potential insurance rate increases. Some states impose more severe penalties, including possible suspension of motorcycle endorsements.

Can I lane split in stopped traffic?

Only in states that specifically permit lane filtering (Utah, Arizona, Montana, Colorado, Minnesota) or lane splitting (California). Even in these states, specific conditions regarding speed limits and traffic flow must be met.

Is lane splitting safer than sitting in traffic?

Research suggests that lane splitting, when performed correctly under appropriate conditions, may reduce rear-end collision risks for motorcyclists. However, it requires skill and increases exposure to other hazards. Safety depends heavily on rider experience, traffic conditions, and speed differentials.

Will more states legalize lane splitting?

The trend suggests more states may legalize lane filtering in coming years. Several state legislatures are actively considering bills to permit the practice under restricted conditions.

What should drivers know about lane splitting?

In states where lane splitting or filtering is legal, drivers should:

• Check mirrors and blind spots before changing lanes
• Avoid blocking motorcyclists who are legally splitting or filtering
• Not attempt to prevent legal lane splitting
• Be aware that motorcycles may be passing between lanes

How fast can I go while lane splitting?

Speed limits vary by state:

• California: No specific speed limit, but recommended to travel no more than 10 mph faster than traffic
• Utah: Maximum 15 mph while filtering
• Arizona: Cannot exceed 15 mph while filtering
• Minnesota: Cannot exceed 15 mph over the speed of traffic
• Montana and Colorado: Speed restrictions apply based on specific conditions

Can I get a ticket for lane splitting even if I think it’s safer?

Yes. In states where lane splitting is illegal, safety concerns do not provide legal justification for the practice. Courts consistently uphold citations for lane splitting in states where it’s prohibited, regardless of the rider’s reasoning.
