Arkansas Truck Weight Limits and Permit Sources

At-a-glance summary

Field-level reference data

Arkansas weight compliance tends to route through a single agency. ARDOT handles both the permit side and publishes the size and weight regulation materials that give the enforcement context. Having those two pieces under the same umbrella means less cross-agency searching when a permit, citation, or field value needs verification. Gross, single-axle, and tandem weight rows here draw from the federal Interstate baseline and the FHWA state law compilation; state-specific limits for non-Interstate routes are in that compilation.

Reading the Arkansas weight table

Each row in the weight table runs as a separate check. Gross weight passing doesn’t mean drive tandem or trailer tandem limits are clear. The bridge formula check runs independently of both. For Arkansas Interstate routes, the federal baseline applies. Off the Interstate — on US highways, state routes, or local roads — the FHWA state law compilation for Arkansas is the reference for what applies on that road class.

When an axle reading is close to a limit, identify which specific row is the issue before making any adjustment. A fifth-wheel slide or tandem move that shifts weight from one group may bring another group closer to its limit. The scale ticket should show axle group readings both before and after any adjustment.

Permit and route authority in Arkansas

ARDOT Permits is the permit authority for Arkansas over-limit moves. Applications go through ARDOT before the move. The permit covers the specific route, vehicle configuration, axle weights, and travel window — none of those terms automatically carry over to a different trip. If equipment changes, the route changes, or the travel date shifts significantly, the permit needs to be reviewed before that new move is released.

Arkansas permit documentation should include the issued permit, route, travel dates, axle configuration, current scale ticket, and any agency conditions. A permit number alone isn’t sufficient for a compliance file.

Seasonal, route, and local checks

No statewide seasonal or frost weight restriction was confirmed for Arkansas in this review. Arkansas’s geography and climate don’t produce the same frost-law activity seen in northern states, but local bridge postings, construction zone restrictions, and permit-route conditions can still affect specific roads. The seasonal field being unconfirmed means no statewide source was found — it doesn’t mean every route is clear of restrictions.

Tickets and enforcement notes

ARDOT’s size and weight regulation materials cover the enforcement context for Arkansas weight violations. No specific fine schedule was confirmed in this review — the fine structure field references ARDOT’s official materials but remains medium confidence because the actual amount depends on the specific citation. If a citation is issued, use the citation document and current ARDOT enforcement materials as the starting point, not this page’s fine field.

A scale ticket shows measured weight; it doesn’t establish permit authority or resolve a citation. Keep the ticket, permit, and citation records separately and clearly labeled.

Source-strength notes for Arkansas

Across 6 source records, this page carries 3 high-confidence, 23 medium-confidence, and 3 low-confidence field designations. High-confidence fields — permit agency, permit office name, permit URL — have direct official support. Medium-confidence fields are supported by ARDOT official materials but involve some inference. Seasonal and fine fields are the lower-confidence areas.

Building an Arkansas source file

A practical Arkansas dispatch file includes the scale ticket, ARDOT permit documentation, approved route, and any agency conditions. The axle weight table, permit office list, seasonal restrictions, and overweight fine sources pages add context for routes that cross state lines.

For drivers, How to Read a CAT Scale Ticket covers ticket reading, How to Slide Tandems covers distribution, and Bridge Formula Explained covers bridge formula spacing.

In Arkansas, recordkeeping does not need to be elaborate. It needs to show what was measured, what source was opened, when it was checked, and which field mattered.

When the issue starts at the scale, use How to Read a CAT Scale Ticket first. If the fix involves distribution or spacing, continue with How to Slide Tandems or Bridge Formula Explained.
