Alaska Spring Thaw Weight Restrictions (Frost Laws)

Alaska Spring Thaw Weight Restrictions

Break-up restrictions are issued regionally by DOT&PF. The season is later and longer than any lower-48 state, which is why this row has its own window rather than sharing the northern-tier default.

Check Alaska DOT&PF — Measurement Standards & Commercial Vehicle Compliance before you dispatch.

The source, and how we read it

HTML bulletin · Not machine-readablePolled weekly (off season)

Publisher: Alaska Department of Transportation & Public Facilities
Authoritative page: https://dot.alaska.gov/mscvc/
Format: HTML bulletin — Not machine-readable
What we do with it: Watched for change and linked. We do not synthesise a limit from a map or a PDF.
Posting season: 03-01 to 06-30 — Alaska thaws later and over a longer span than the lower 48, and DOT&PF issues break-up restrictions region by region from early spring into midsummer.
Polling cadence today: Outside Alaska's posting window by 71 days — polled weekly, so an unscheduled restriction and a broken source are both found before the season opens.
If our copy goes stale: It errs toward showing a restriction the state has already lifted, because this source publishes only what is currently in force.
