Oregon matches the federal axle limits at 20,000 lb single and 34,000 lb tandem, with a group-axle table reaching 80,000 lb at 57 feet or more. Its statutory width is the outlier: Table I sets 8 feet (96 inches), narrower than the 102 inches most states codify, though ORS 818.100 layers exemptions on top for safety accessories and other equipment.

1 Limits and thresholds
| Property | Value | Authority |
|---|---|---|
| Max gross weight | 80,000 lb[1]Table maximum, 7+ axles at 57 ft or over. Oregon is genuinely table-driven — actual limits vary by axle count and spacing. | ORS 818.010(3), Table III |
| Max single axle | 20,000 lb[1] | ORS 818.010(2), Table II |
| Max tandem axle | 34,000 lb[1] | ORS 818.010(2), Table II |
| Oversize permit above (width) | 96 in[1]Stated as 8 ft — narrower than the 102 in norm. ORS 818.100 adds exemptions, e.g. safety accessories may exceed Table I by 2 in per side. | ORS 818.080(1), Table I |
| Oversize permit above (height) | 14 ft[1] | ORS 818.080(1), Table I |
| CDL disqualification — first major | 1 year for a first conviction while operating a CMV or a non-CMV; 3 years if operating a CMV transporting placarded hazardous materials. Applies to alcohol/controlled-substance influence, 0.04+ BAC in a CMV, test refusal, leaving the scene, using the vehicle in a felony, driving while disqualified, and causing a fatality by negligent operation.[2]Federal floor. A state may impose longer periods but may not go below this; verify state law before relying on it. | § 383.51(b), Table 1 |
| CDL disqualification — lifetime | Life for a second conviction of any combination of the Table 1 major offences in a separate incident. A state MAY reinstate after 10 years following an approved rehabilitation programme — § 383.51(a)(6) — but not after a subsequent disqualifying conviction. Felony manufacture/distribution of a controlled substance, and severe forms of human trafficking, draw life with NO 10-year reinstatement.[2]Federal floor. The 10-year reinstatement is permissive — states are not required to offer it. | § 383.51(a)(6), (b) Table 1 items (9)–(10) |
