How we check what we publish

A road conditions map, and guides to the rules

Trucker Route is a free road conditions map for truck drivers and a set of reference guides to the rules that change from state to state: weight and length limits, chain laws, speed limits, and the rest of the regulation sections. It is built by Sergei Kulnev (see about).

A guide with a byline names its author, and each author has a profile under authors listing every page they wrote. To reach us about anything on this site, write to support@trucker-route.com.

From the text that sets the rule

A rule on this site is only as good as the text it came from. Every record in the regulation sections names its statute and links the source it was checked against: the state code or administrative rule, the eCFR, the state DOT or state police, FMCSA. The federal trailer length tables are generated from the eCFR text of 23 CFR 658. News reports, law firm pages and encyclopedias can point us to a rule, but a rule, a fine or a limit on this site has to trace back to the text that sets it. News reports and local histories are cited for context, such as what a closure cost or why a road was built.

Live readings come from the agencies that publish them: state DOT feeds, the National Weather Service, NIFC and NASA for wildfires, USGS for earthquakes, FEMA for disaster declarations. Statistics come from FMCSA, NHTSA and FHWA. A company's own facts, such as a bypass service's coverage or price, come from that company's own pages.

Not every page meets this yet. Many of the older mountain pass and interstate guides cite Wikipedia in their text. They have not been through the check described below, and none of them carries a byline.

Read back against the source, field by field

When a section is checked, every record in it is read back against its source, one field at a time: the limit, the fine, the dates, the statute number. A proposed correction is kept only if a second, independent pass fails to refute it. Where official sources disagree with each other, the disagreement goes to the owner to decide.

• The 22 regulation sections were checked this way in July 2026, and the chain laws again in September 2026.
• The ten guides that carry a byline were checked claim by claim on September 30, 2026, and rewritten.
• A record marked as less certain says so on its page, and tells you to confirm it with the state DOT before you rely on it.

Every regulation state page also says what it is: reference information for planning, not legal advice. Laws change, and posted signs and the current statute come first.

A date is a change, not a rebuild

Redeploying the site or rebuilding a page moves none of these dates.

Last reviewed

On a regulation page: the month its section was last checked against its sources.

Updated

On a blog post or a guide with a byline: the day its text last changed.

Live readings

A reading shows the time the agency reported it. A mountain pass reading that no feed has confirmed for 24 hours is shown as no current report.

For search engines

The modified date in a page's structured data and in the sitemap follows the same rule: the day its content changed. Only pages that really change from one day to the next, like the map and the live incident lists, carry today's date.

What the feeds say, as they say it

Live incident feeds come from 41 state DOTs, 6 more send work zones only, and there is no feed yet for Connecticut, New Jersey or Rhode Island. State DOT incident feeds and National Weather Service alerts are read every 15 minutes. Work zone, wildfire and earthquake feeds are read every 60 minutes, FEMA disaster declarations twice a day, and the FMCSA, NHTSA and FHWA statistics once a day. Each page keeps its own short cache on top, so it can trail a feed by up to half an hour, and longer on the statistics pages, which change once a day.

We do not edit what the feeds report and we cannot vouch for it beyond its source. If an agency's feed is late, wrong or down, the map is too. Where we can tell that a feed has gone quiet, the page says so instead of reporting a clear road.

When a page is wrong

The guides, the regulation pages and the data pages end with a Report an error button. It sends us the page address with your note; an email address is optional and needed only if you want an answer. You can also write to support@trucker-route.com.

We check every report against the source. When a report or our own check changes a fact a reader could rely on, the change is listed, with its date and what the page said before, under corrections. Style edits, layout fixes and dead links are not listed.

Articles from readers

Readers can suggest a topic or pitch an article on write for us. Nothing is published automatically. An outside article goes through the same check as a guide of ours, is edited to our style guide, and is published under its author's name with "Reviewed by" and the editor who answers for it. Links inside an article go to primary sources only.
