About this list

What is covered, where it comes from, and what the rules say

Weigh stations, ports of entry and commercial vehicle enforcement facilities, from the data the state transportation agencies publish themselves. Listed by highway, with direction, mile marker and phone number where the state gives them.

The largest concentration is in Flagler County: 7 of 381 (2%). Other cities covered include Escambia County (6), Marion County (6), Jackson County (5), Lincoln County (5), Nassau County (5), and 253 more.

By county, the 381 entries fall across 206 counties; the largest are Flagler (7), Escambia (6), Lincoln (6), Marion (6).

These 381 entries come from a register that publishes no listing dates at all. For those, the only thing that can honestly be said is that the facility appeared in the state register when it was last refreshed, on September 27, 2026. No issue, renewal or expiry date is shown for them, and none is guessed.

The listing classes represented here are Weigh station (153), Port of entry (94), Commercial vehicle enforcement facility (53), Weigh in motion station (47), Static Scale (15), and 3 more. The class is the source's own wording, not a label applied here.

146 of 381 publish a phone number. Phone numbers are normalized to one format here; the registers publish them several different ways.

The map positions come from the register itself rather than from an address lookup. No distance claim is made anywhere in this text; the "nearest to me" list computes straight-line distances in your own browser from your own location.

What a weigh station checks

States weigh trucks to enforce the size and weight limits on their roads. On the Interstate system the federal limits in 23 CFR 658.17 are 80,000 pounds gross vehicle weight, 20,000 pounds on any one axle and 34,000 pounds on a tandem axle, with lower gross weights where the bridge formula requires them. Many stations also carry out safety inspections of the driver and vehicle. Check a load against the axle limits before you leave with the bridge formula calculator.

What is in the list

There is no national list of weigh stations. This one is built from the states that publish their own: the transportation departments of Alaska, Arizona, California, Colorado, Florida, Idaho, Illinois, Iowa, Minnesota, Montana, New Mexico, North Carolina, Oklahoma, Utah and Wisconsin, the Wyoming Highway Patrol, and the Puget Sound Regional Council’s list of Washington State scale houses. Proposed, closed and inactive sites are left out, and in Montana only the staffed fixed scales are listed, not the roadside pull-outs used with portable scales. In Minnesota only the stations whose published street address could be placed on the map are listed.

What it does not show

  • Whether a station is open now. Stations open and close through the day; the data does not say when.
  • Bypass programs. Which stations take PrePass or Drivewyze is not in the state data.
  • Other states. States that do not publish their weigh stations as data are not listed yet.

Questions about weigh stations

Is this every weigh station in the US?
No. There is no national list; this covers the states that publish their weigh stations and ports of entry as open data.
Does it show if a weigh station is open?
No. The state data gives the location, not the opening hours. Watch the signs on the approach.
What is a port of entry?
Some western states run their weigh stations as ports of entry, where carriers also check in for permits, registration and fuel tax at the state line.
