I pulled Oregon's roadside inspection totals for August 2023 through October 2026, a 39-month window, and set them beside the national totals for the same period. Oregon recorded 60,054 inspections and 89,634 violations, about 1.49 violations per inspection. The figure that separates Oregon from the rest of the country is the out-of-service count: 25,920 violations where the vehicle or driver was ordered to stop until the condition was corrected.
The full state breakdown is on the Oregon insights page if you want to check my arithmetic against the raw counts. Everything below comes from those same totals.
The out-of-service share
Out-of-service rate here means out-of-service violations divided by all violations. Oregon's is 28.9 percent. The national figure over the same window is 17.7 percent. In plain terms, nearly three of every ten violations written in Oregon stop the operation on the spot, compared with a little under two in ten nationally.
Measured per inspection, Oregon averages about 43 out-of-service violations for every 100 inspections. Dispatchers should care about that number, because it tells you how often a single roadside stop turns into a delay.
Drivers account for the gap
Splitting the totals by category is where the pattern gets sharp.
- Driver violations: 19,567 total, 10,585 out-of-service, a 54.1 percent rate. Nationally the driver rate is about 24.0 percent.
- Vehicle violations: 34,985 total, 15,335 out-of-service, a 43.8 percent rate. Nationally it is about 23.9 percent.
- Hazmat violations: 422 total, 128 out-of-service, a 30.3 percent rate, against roughly 26.6 percent nationally.
Oregon's vehicle out-of-service rate also runs above the national figure, but the widest distance is on the driver side. More than half of Oregon's driver violations remove the driver from the road, more than double the national share.
The hazmat sample is small, so I would not build a conclusion on it. Treat it as something to watch.
What the totals cannot tell you
These are aggregates, and they leave a lot out.
- They don't say why. A high driver out-of-service share could reflect enforcement focus, the kinds of carriers and routes inspected, or how officers write up conditions. The totals don't separate those causes.
- Inspection mix moves the numbers. States differ in where officers inspect and what they target. A heavily trafficked freight corridor and a rural stretch can produce very different records.
- They are not carrier scores. Oregon's 28.9 percent describes tens of thousands of inspections across many companies. It says nothing about any single fleet.
- Averages hide spread. 1.49 violations per inspection is a mean. Most inspections may record nothing, and a few may record many.
What a carrier can do with it
First, check driver-side readiness before a run into Oregon, not at the scale house. Medical certificate dates, license status, and hours-of-service records are things an inspector can verify in minutes, and they are the items driving the out-of-service rate here. Second, pull your own inspection history by state. A pattern in your records is worth more than a national average. Third, if you run Oregon regularly, read the last several violations your drivers received, not just the total count.
Vehicle-side conditions still matter. Federal rules under 49 CFR Part 393 set equipment standards, and 49 CFR Part 396 covers inspection and maintenance. Read the rule text before deciding a condition is minor.
Key takeaways
- Oregon's out-of-service share is 28.9 percent of violations, against 17.7 percent nationally.
- The gap is mostly on the driver side: 54.1 percent of Oregon driver violations were out-of-service, against about 24.0 percent nationally.
- Aggregates show where enforcement lands. They do not show why, or how a given carrier will fare.
