Motorcycle Helmet & Lane-Splitting Laws in Oregon

Oregon takes a firm line on two motorcycle-specific rules. It requires a helmet for absolutely everyone on a motorcycle, no exceptions for age or trip length, and it has never legalized lane splitting or filtering, despite lawmakers trying at least three times since 2021. If you're recovering from a motorcycle crash in Oregon, both rules can matter to your injury claim, not just to whether you got a ticket.

The helmet law: universal, with two narrow exceptions

Oregon doesn't distinguish between operators and passengers, or between short trips and long ones. Under ORS 814.269, a motorcycle operator who isn't wearing a motorcycle helmet has committed a Class D traffic violation.¹ The same requirement extends to passengers under ORS 814.275, to moped riders under ORS 814.260, and an operator can be cited separately under ORS 814.280 for letting a passenger ride bare-headed.²³⁴

There are only two exemptions, both spelled out in ORS 814.290:

• Riding inside an enclosed cab, such as a fully enclosed three-wheeled autocycle.
• Operating or riding a three-wheeled vehicle that tops out under 15 mph.⁵

That's the entire list. Insurance status, riding experience, and how far you're going don't factor in.

Oregon also regulates how a passenger rides. Under ORS 814.325, it's a Class B traffic violation to carry a motorcycle passenger anywhere but a permanent, regular seat, in a way that interferes with the operator's control, or without footrests, unless the passenger is in a sidecar or an enclosed cab.⁶ Combined with the helmet rule, a passenger has to be properly seated and properly geared before the bike leaves the driveway.

The helmet itself has to meet a federal standard. Oregon's DMV motorcycle and moped manual tells riders to check for a label reading "DOT, FMVSS No. 218, CERTIFIED" before trusting a helmet to satisfy the law.⁷ A novelty "beanie" helmet sold without that certification doesn't count, even shaped like the real thing.

Eye protection is a different story. ODOT recommends a full-face helmet or a shatter-resistant face shield, and warns that a windshield, eyeglasses, or sunglasses won't do the job in a crash.⁷ That's guidance, not law. Oregon has no standalone eye-protection statute the way some states do, so skipping the shield won't get you a ticket.

A first helmet offense carries a $115 presumptive fine, the standard amount for a Class D violation under ORS 153.019, with a court able to set it as low as $65 or as high as $250 for an individual.⁸

Getting endorsed to ride at all

Before any of this comes up, a rider needs a motorcycle endorsement. ORS 807.175 requires completion of an approved motorcycle rider education course, established under ORS 802.320, before DMV will add the endorsement to a license.⁹ Riding without one doesn't change the helmet or lane-splitting rules directly, but it can surface in a claim. An insurer or defense attorney may argue an unendorsed rider was operating unlawfully in some way connected to the crash, even when the endorsement itself had nothing to do with causing it.

Lane splitting and filtering are still illegal

Unlike California, Oregon hasn't legalized any form of lane splitting or filtering, and that isn't for lack of trying. ORS 814.240 makes it a Class B traffic violation for a motorcycle or moped operator to pass another vehicle while sharing its lane, or to ride between lanes of traffic or between rows of vehicles at all, in any traffic condition.¹⁰ Riding side by side with another motorcycle in the same lane is specifically allowed; splitting past a car or truck is not.

A Class B violation carries the same $265 presumptive fine as Oregon's handheld cellphone law, with a court able to impose up to $1,000.⁸

Lawmakers have tried to change this more than once. Then-Governor Kate Brown vetoed a bipartisan lane-filtering bill in 2021, writing that law enforcement and the public remained concerned it was unsafe for both riders and drivers.¹¹ A similar bill passed the Senate 27-2 in 2023 but stalled in the House. The most recent attempt, House Bill 3542, would have allowed filtering on highways posted at 50 mph or higher once traffic slowed to 10 mph or less, capped a rider's speed advantage at 10 mph over surrounding cars, and raised the penalty for improper passing to a Class A misdemeanor with a $2,000 fine.¹² It never got a floor vote. The bill died in committee when the 2025 regular session adjourned on June 27, 2025.¹³ As of 2026, no version of lane splitting or filtering is legal anywhere in Oregon.

How a citation or a bare head follows you into an injury claim

Oregon runs on modified comparative negligence. A rider can still recover damages after a crash as long as they aren't found 51 percent or more at fault, with the award reduced by whatever share of fault the rider carries.¹⁴ Both a helmet violation and a lane-splitting citation can feed into that percentage, but not automatically, and not in the same way.

For seat belts, Oregon has a specific statute that caps the damage. ORS 31.760 lets a defendant point to a driver's or passenger's nonuse of a safety belt, but only to reduce damages, and only by up to 5 percent.¹⁵ That statute is written for belts and harnesses in an enclosed vehicle. It says nothing about motorcycle helmets, and nothing in Oregon law extends its 5 percent ceiling to an unhelmeted rider. That means there's no statutory floor protecting a rider's recovery the way there is for an unbelted driver. A defense attorney is free to argue a full comparative-fault allocation instead of a hard 5 percent limit, as long as they can tie the missing helmet to the specific injuries claimed. A rider with a shattered femur or road rash from being dragged across pavement usually has a strong answer: a helmet wouldn't have changed that outcome, however the defense frames it.

A lane-splitting citation works differently. It's evidence the rider broke a traffic law, which can support an argument that the rider helped cause the crash, not just that the rider's injuries were worse than they should have been. If the rider wasn't actually filtering between cars when the crash happened, the citation shouldn't move the needle at all. Either way, if you were cited or a report lists you as splitting lanes, get a copy of the crash report early. What the responding officer wrote down about lane position and speed often ends up driving the whole fault argument.

None of this is something to sort out alone. An attorney who handles motorcycle cases regularly knows how Oregon juries tend to weigh helmet and lane-position evidence, and can push back when a defense overreaches. The legal directory is a place to start looking for one.
