Why Status Is Unknown
The document retrieved is Alaska DOT&PF's standing Weight Restriction Bulletin a permanent reference document codifying restriction calculation rules under 17 AAC 25.100. It is not a seasonal activation notice, a lift notice, or any document that announces a current operational restriction event. No specific highway, milepost, effective date, or active restriction tier is stated. As a result, real-time restriction status cannot be determined from this source alone.
To confirm whether restrictions are currently active on any Alaska state highway, check the live notification portal directly: dot.alaska.gov/mscve/pages/weightrestrictions.shtml.
Alaska Weight Restriction Tiers Reference Table
When restrictions are in effect, they apply at one of three percentage tiers. The table below shows the axle-group pound limits at each tier, plus the unrestricted (100%) baseline. These values are sourced from the standing bulletin and apply to all posted restriction events statewide.
| Restriction Level | Single Axle (lbs) | Two-Axle Group (lbs) | Three-Axle Group (lbs) | Four-Axle Group (lbs) |
|---|---|---|---|---|
| 100% (unrestricted) | 20,000 | 38,000 | 42,000 | 50,000 |
| 85% restriction | 17,000 | 32,300 | 35,700 | 42,500 |
| 75% restriction | 15,000 | 28,500 | 31,500 | 37,500 |
| 50% restriction | 10,000 | 19,000 | 21,000 | 25,000 |
Special Axle and Tire Conditions
- Minimum axle spacing: 8'1" is the minimum spacing between axle groups. Axles spaced less than 8'1" apart are treated as a single axle group for weight calculation purposes.
- Lift axles: Lift axle(s) in the drive group of the power unit are not counted when determining the legal maximum allowable weight.
- Tire tread limit: Maximum allowable weight for all axle(s) is determined by number of tires tire tread width 600 lbs per inch of tread width. This calculation is unchanged at 85%, 75%, and 50% restriction levels.
- Steering axles: Excluded from percentage-based weight restriction calculations per 17 AAC 25.100(b).
Exemptions Detail
- School and municipal buses transporting people: allowed 100% of legal load. No permit required.
- Vehicles en-route within 7 days of the restriction effective date: allowed 100% of legal axle load. Bill of lading required as proof of en-route status.
- Interstate sealed and charged produce vans charged prior to restriction effective date: allowed 100% of legal axle load. Bill of lading required.
- Intermodal (IM) portable tanks or compartments with volume greater than 7,500 liters (1,980 U.S. gallons) per 49 CFR Part 173.32(f)(5): allowed 100% of legal axle load.
- Health and safety permits: Vehicles or loads that exceed weight restriction limits may be issued permits for health and safety concerns.
Dispatch Checklist
- Current restriction status is unknown. The source document does not confirm whether restrictions are active, pending, or lifted as of 2026-04-01 00:00 UTC. Do not assume clearance.
- Check the live portal before every dispatch to Alaska state highways: dot.alaska.gov/mscve/pages/weightrestrictions.shtml.
- If restrictions are active, confirm the posted tier (85%, 75%, or 50%) and use the weight limits table above to determine your legal axle loads.
- Verify exemption eligibility. En-route and produce van exemptions require a bill of lading. Bus exemptions require no permit. Health/safety permits must be obtained in advance.
- State highways only. These notices do not cover local roads.
- Contact DOT&PF directly with questions: 907.365.1210 or visit the weight restrictions portal.
