Contact

What contact is for

The best use of contact is corrections and source suggestions. If a page states something you can show is factually wrong, out of date, or missing a relevant source, that is a useful report. If a link is broken, a calculation result seems off, or a passage is unclear in a way that matters for a safety or compliance decision, that is also useful.

This site is a small independent reference project. Contact is handled manually, without an automated ticketing system. Responses are slower than large-scale support operations — see the note on response timing below.

What we can help with

• Factual corrections: the page URL, the specific sentence or figure, and a source that contradicts it.
• Missing sources: a government, manufacturer, or industry reference that should be cited on a specific page.
• Broken or outdated links: the page, the broken link, and a working replacement URL if you have one.
• Unclear wording: a sentence or section that is ambiguous on a safety or compliance topic.
• Scope gaps: topics that fit the site's subject area and are not yet covered.

What we cannot help with

• Emergency roadside situations — contact a roadside service provider or emergency services.
• Tire inspection or service approval for a specific vehicle, axle load, or operation.
• Compliance determinations, regulatory opinions, or legal advice about specific operations.
• Manufacturer warranty claims or product defect reports — contact the manufacturer directly.
• Shop, dealer, or service provider recommendations for specific locations.

How to write a useful report

The most actionable reports include the exact page URL, the specific sentence or figure in question (not just the general topic), what you believe is wrong or missing, and a source link or CFR section if you have one.

Reports that say "page X is wrong about Y because Z document says otherwise" with a link to Z can be reviewed immediately. Reports that say "something seems off about that page" without specifics take much longer and may not result in a change if the original sources still support the content.

Response timing

Review timing depends on the nature of the issue, source availability, and current workload. Corrections involving safety-critical topics — out-of-service criteria, load capacity thresholds, changes to 49 CFR — are reviewed first. If your report involves a page that is actively misleading readers on a safety topic, note that in your message.

Non-urgent suggestions — additional topics, wording preferences, scope expansions — are reviewed periodically. The site does not commit to a specific response timeline for general suggestions, but all reports that include a specific source reference are read and logged.
