Oregon Court Strikes Progressive's Motorcycle UIM Exclusion in August 2026 Ruling

An Oregon appeals court ruled on August 19, 2026 that Progressive cannot use a "regular use" exclusion to deny underinsured motorist coverage to two injured motorcyclists, a decision that could reshape how insurers write motorcycle policy language across the state.

The case, reported by Insurance Business, centers on two riders hurt in separate crashes caused by underinsured drivers. Their injuries exceeded the limits of their motorcycle UIM policies, and both turned to their Progressive auto policies covering other vehicles for additional relief. Progressive said no. According to Insurance Business, the insurer cited a "regular use" exclusion, and the court ultimately found that exclusion violated Oregon's statutory minimum coverage standard.

Why two injured Oregon motorcyclists were denied extra coverage

Both riders held Progressive auto policies on vehicles that were not involved in their accidents. That matters because Oregon law allows policyholders to stack UIM benefits across multiple policies when their injuries surpass one policy's limits.

Progressive's refusal rested entirely on a single clause: a "regular use" exclusion. The exclusion blocked coverage for injury suffered while "occupying or being struck by a motor vehicle that is owned by or furnished for the regular use of you, a relative, or a rated resident," unless that vehicle was a "covered auto" under the policy.

Their motorcycles didn't qualify as "covered autos." That meant the extra coverage they paid for on their other vehicles was effectively unavailable to them the moment they climbed on a motorcycle. The trial court initially sided with Progressive, granting summary judgment and finding the facts didn't trigger the provision. The riders appealed, and won.

How Progressive's 'regular use' exclusion works, and where it broke down

The policy language at issue is specific. Progressive defined "covered auto" to mean an "additional auto" or "replacement auto." It then defined "auto" as a land motor vehicle "with at least four wheels."

Motorcycles have two wheels. That's the entire problem.

By limiting the definition of "auto" to four-wheeled vehicles, Progressive effectively excluded motorcycles from the coverage protections its own policyholders had purchased. If your motorcycle doesn't count as a "covered auto," the regular use exclusion can be used to deny you benefits from your other Progressive policies when you're injured on that motorcycle.

A second structural gap compounded the problem. Oregon's model policy preserves coverage for substitute vehicles, temporary replacements you might use while your own vehicle is in the shop, for example. Progressive's policy covered "additional" and "replacement" autos, which require either ownership or permanency. Substitute vehicles, which are neither owned nor permanent, fell through the gap entirely.

Oregon's coverage-to-coverage test and what the statute actually requires

Oregon's legal framework for underinsured motorist coverage motorcycles disputes is built on a straightforward but powerful standard.

Under Oregon Revised Statutes 742.504, every auto insurance policy must offer UIM coverage that is "no less favorable in any respect" than the state's model policy. That phrase, "no less favorable in any respect", is the coverage-to-coverage test, and it sets a high bar.

The court found that Progressive's policy failed on two counts. First, Oregon's statute explicitly defines "vehicle" and "motor vehicle" to include two- and three-wheeled devices, with motorcycles counted among them. Progressive's four-wheel definition of "auto" contradicted that statutory inclusion, which the court said "materially narrows the coverage available."

That's a direct quote from the ruling, and it's the crux of the decision. If a policy definition narrows what the statute requires to be covered, the definition cannot stand.

Second, the substitute-vehicle gap described above also failed the coverage-to-coverage test. The model policy protects riders in substitute vehicles. Progressive's did not. Both failures, taken together, meant the "regular use" exclusion was unenforceable as written.

How Oregon's model UIM policy compares to what Progressive offered

The table below lays out the specific points of conflict between Oregon's statutory model policy and the Progressive policy language the court reviewed.

The contrast is stark. Oregon's legislature wrote a model policy that explicitly brings motorcycles under the UIM umbrella. Progressive's four-wheel definition drew a hard line that kept them out.

For Oregon motorcycle riders holding multiple Progressive policies, that line meant the difference between having meaningful UIM protection and having none at all when it counted most.

Why Progressive's Supreme Court precedent argument didn't hold up

Progressive had one more card to play: a recent Oregon Supreme Court ruling that, it argued, had already approved the same exclusion.

The appeals court rejected that reading. The court noted the question "was neither presented nor argued before the court in that case." In legal terms, that means the Supreme Court's ruling carried no precedential weight on this specific issue. A court cannot establish binding precedent on a question that was never actually litigated before it.

That distinction is significant. Progressive was not simply citing a case that went against the riders, it was citing a case where the relevant issue was never decided. The appeals court found that argument unpersuasive, reversed the trial court's summary judgment in Progressive's favor, and remanded the case.

With the exclusion stricken, the court held that the riders were entitled to UIM coverage under their auto policies.

What this means for you

If you ride a motorcycle in Oregon and hold auto insurance policies on other vehicles, pull out those policies and read the definition of "auto" carefully. Check whether your insurer uses a four-wheel definition that could exclude your motorcycle from coverage stacking rights. Review whether your policy covers substitute vehicles, not just "replacement" or "additional" autos. The Save Max Quote Index, drawn from 3.3 million+ real quote requests, shows that riders frequently hold separate motorcycle and auto policies without realizing those policies may interact in ways that limit their UIM benefits. Use the ruling's two failure points, the four-wheel definition and the substitute-vehicle gap, as your checklist when comparing policies. For a broader look at how Oregon auto insurance rules stack up, and how neighboring states like Washington and California handle similar UIM questions, start with your state's coverage requirements before you buy.

The bottom line on UIM coverage and motorcycle policies

"Progressive defined 'auto' as a land motor vehicle 'with at least four wheels.'"

That single definition cost two injured Oregon riders access to underinsured motorist benefits they had paid for across multiple policies. The Oregon Court of Appeals found that definition, when combined with a substitute-vehicle gap, violated the state's statutory requirement that UIM coverage be "no less favorable in any respect" than the model policy under ORS 742.504.

The court said the four-wheel limit "materially narrows the coverage available", a standard that, once triggered, means the exclusion cannot stand.

The ruling has been remanded for further proceedings, but the exclusion itself has been stricken. Oregon insurers who rely on similar "regular use" language with four-wheel auto definitions should expect pressure to revise those provisions. For policyholders, the lesson is immediate: policy definitions that seem like fine print can determine whether you have any coverage at all after a serious crash. Review your definitions now, not after an accident.
