Lane splitting is illegal in most U.S. states, but legal in California and a few others

Lane splitting — riding a motorcycle between two lanes of traffic — is against the law in 49 states. Only California explicitly permits it, though a small number of other states have no law specifically forbidding it, which is different from making it legal. Even where it is not explicitly banned, police can still ticket you under reckless driving or unsafe speed laws. The legality depends entirely on which state you are in, and the rules do not change based on traffic conditions or how safely you think you are riding.

If you ride a motorcycle, you need to know the law in your state before you split lanes. Doing it where it is illegal can result in a ticket, a fine, points on your license, and increased insurance rates. In some states, a lane-splitting ticket can also be used against you in a civil lawsuit if you are in an accident, even if you were not at fault for the collision itself.

Key Takeaways

  • California is the only state where lane splitting is explicitly legal; all other states either ban it outright or have no specific law, which means police can cite you under other traffic laws.
  • Even in states without a specific lane-splitting law, you can be ticketed for unsafe speed, reckless driving, or improper lane change.
  • A lane-splitting ticket can increase your insurance rates and may be used against you in a lawsuit if you are in an accident.
  • Some states are considering legalizing lane splitting, but as of now, only California has done so.

Where lane splitting is explicitly legal

California is the only state that has written lane splitting into law. In 2016, California codified what riders had been doing for years by passing Assembly Bill 51, which states that motorcycles may pass other vehicles on the left by driving between lanes. The law does not set a specific speed limit for lane splitting, but it does require that the maneuver be done in a safe and prudent manner. California Highway Patrol guidelines suggest that lane splitting is safer when traffic is moving at 50 miles per hour or less and when the speed difference between the motorcycle and other vehicles is no more than 10 miles per hour, but these are guidelines, not legal requirements.

Even in California, lane splitting is not a free pass. You still have to ride safely and follow traffic laws. If you cause an accident while lane splitting, you can be held liable. If you are ticketed for unsafe lane splitting, you can contest it in court, but the burden is on you to show that your riding was safe and prudent.

States where lane splitting is explicitly illegal

The vast majority of states have laws that directly prohibit lane splitting. These states include Texas, Florida, New York, Illinois, Pennsylvania, Ohio, Georgia, North Carolina, Virginia, and many others. In these states, lane splitting is treated as an illegal lane change or unsafe passing, and you can be ticketed and fined. The fine amount varies by state — some states impose fines of $100 to $300, while others go higher. You will also typically receive points on your driving record, which can raise your insurance rates.

Some states do not name lane splitting by name but have laws broad enough to cover it. For example, a state might have a law against "unsafe lane changes" or "improper passing," and a police officer can use that law to ticket you for lane splitting. The result is the same: a ticket, a fine, and points on your record.

States with no specific lane-splitting law

A handful of states — including Montana, Missouri, and a few others — do not have a specific law that mentions lane splitting. This does not mean it is legal. Instead, it means that police officers have to cite you under a different law, such as reckless driving, unsafe speed, or improper lane change. You can still be ticketed, fined, and have points added to your license. The outcome is the same as in states with explicit lane-splitting bans; the only difference is the specific law cited on the ticket.

If you ride in a state without a specific lane-splitting law, do not assume you can split lanes freely. Talk to a local motorcycle group or a traffic attorney in that state to understand what laws explore and how police typically enforce them. The safest approach is to treat lane splitting as illegal unless you are in California.

What happens if you get a lane-splitting ticket

A lane-splitting ticket is a moving violation, which means it goes on your driving record. Your insurance company will see it, and your rates will likely go up. The increase can be 10 to 30 percent or more, depending on your insurer and your driving history. You will also receive points on your license — the number varies by state, but it is typically 2 to 4 points. Accumulate too many points, and your license can be suspended.

If you are in an accident after receiving a lane-splitting ticket, the ticket can be used against you in a civil lawsuit, even if you were not at fault for the accident itself. An insurance company or the other driver's attorney may argue that you were already driving recklessly by lane splitting, so you were more likely to cause or contribute to the accident. This is one reason why lane splitting carries real financial risk beyond the when ready fine.

How lane splitting is treated in insurance claims

If you are in an accident and you were lane splitting at the time, your insurance company may deny your claim or reduce the amount they pay. Some insurance policies explicitly exclude coverage for lane splitting. Even if your policy does not have an explicit exclusion, the insurance company may argue that you were driving recklessly and therefore violated the terms of your policy. This can leave you personally liable for damages to the other vehicle and for any injuries.

If you are injured in an accident while lane splitting, you may have a harder time recovering damages from the other driver, even if they were at fault for the accident. A court or jury may find you partially at fault for the accident because you were lane splitting, and your recovery may be reduced accordingly. This is called comparative negligence, and it can significantly reduce the money you receive.

States considering or testing lane splitting

Several states have introduced bills to legalize or study lane splitting, including Washington, Oregon, Texas, and Hawaii. Some of these states have conducted studies on whether lane splitting is safer or more dangerous than traditional riding. The results are mixed, and the debate continues. However, as of now, none of these states have passed a law legalizing lane splitting. If you ride in one of these states, lane splitting is still illegal, even if there is active discussion about changing the law.

Before you assume a state has legalized lane splitting, check the current law. State laws change, and what was illegal last year may be legal this year, or vice versa. The safest approach is to check your state's motorcycle handbook or contact your state's Department of Motor Vehicles before you ride.

Frequently Asked Questions

Can I lane split if traffic is stopped or moving very slowly?

No. Lane splitting is illegal in all states except California, regardless of traffic speed. Even in California, where it is legal, you should only do it when it is safe and prudent. If you are ticketed for lane splitting in a state where it is illegal, the traffic speed does not matter — you can still be fined and receive points on your license.

What is the difference between lane splitting and lane filtering?

Lane filtering is moving through stopped or nearly stopped traffic, while lane splitting is moving through traffic that is moving at any speed. Some states distinguish between the two and may allow filtering but not splitting. However, in most U.S. states, both are illegal. Check your state's specific laws to see if this distinction applies where you ride.

If I lane split in California, can I be sued if I cause an accident?

Yes. Lane splitting is legal in California, but that does not make you immune to liability. If you cause an accident while lane splitting, you can be held responsible for damages. You can also be ticketed if a police officer determines that your lane splitting was not safe and prudent. Legal does not mean consequence-free.

Will a lane-splitting ticket affect my motorcycle insurance?

Yes. A lane-splitting ticket is a moving violation and will appear on your driving record. Your insurance company will see it, and your rates will likely increase. The amount of the increase depends on your insurer and your driving history, but increases of 10 to 30 percent are common. Some insurers may even refuse to renew your policy.

Can I contest a lane-splitting ticket in court?

Yes, you can contest any traffic ticket in court. However, you will need to show that you were not lane splitting or that your lane splitting was safe and legal in your state. If you were lane splitting in a state where it is illegal, your defense options are limited. If you were lane splitting in California, you may be able to argue that your riding was safe and prudent, but this requires evidence and is not may provide to succeed.
