Official sources and reference links used by TruckTripGuide.com.

7 min Updated 2026-05-27 Readers

This site uses official sources as anchors for regulatory, safety, weather, and public-resource topics. Source links are provided on relevant pages so readers can verify current information.

Source pages can move or change. When a linked official resource changes, the site should be updated rather than guessing from memory.

All primary sources used on this site are official government or agency publications — federal regulatory summaries, official safety resources, state DOT traveler information portals, and official public resources. No private research, industry association lobbying material, or commercial content is used as a primary source for any regulatory or safety claim.

Federal regulatory sources

The primary federal sources for HOS and ELD content are the FMCSA Summary of Hours of Service Regulations and the FMCSA Electronic Logging Devices page at fmcsa.dot.gov. These are the official federal sources for interstate property-carrying driver rules. All HOS summaries on this site are simplified for planning education — they do not replace reading the current official regulatory text or consulting with a compliance professional for carrier-specific decisions.

The FMCSA Safety Programs page is the primary anchor for safety-related planning content. The FHWA Truck Parking program page is the primary federal source for national truck parking context and is used in parking planning guides, rest area sections, and hub page content.

Weather and safety sources

Weather planning content is anchored to National Weather Service (NWS) official safety education resources: the NWS Winter Weather Safety page, Winter Weather Warnings and Advisories, Wind Safety, and Severe Weather resources. The NWS resources are official NOAA publications and are updated independently by the agency. This site links to the NWS resources directly rather than summarizing them, because current official NWS guidance is more reliable than any secondary summary.

OSHA Winter Weather Hazards and Precautions is used as a supplementary safety source for workplace and cold-weather driving hazard framing. It is an official OSHA publication and is used in the context of driver safety planning, not as a substitute for FMCSA regulatory guidance.

State DOT sources

Each state planning guide and corridor guide references the official state DOT traveler information system for that state — the 511 portal, DriveTexas, Caltrans QuickMap, and similar official state portals. These are the correct sources for current road conditions, construction, and travel advisories for each state. This site links to the official state portal and explains what types of information are available there — it does not replicate or cache state road condition data.

State commercial vehicle enforcement and permit sources are referenced for state-specific compliance context in state planning guides. These include state DOT commercial vehicle pages, state public safety commercial vehicle enforcement divisions, and state permit offices. These sources are used to point readers to the correct official channel for state-specific questions — not to provide legal compliance advice.

What these sources do not cover

  • Current fuel prices — this site does not quote live diesel prices and does not use fuel price services as sources.
  • Live parking availability — no source provides real-time truck parking counts that this site uses or republishes.
  • Current road closures or incidents — state DOT portals are the correct source; this site links to them but does not cache their data.
  • Carrier-specific policy — FMCSA and state sources cover federal and state rules; individual carrier policies vary and are the carrier's responsibility.
  • Legal advice — regulatory summaries are simplified for planning education and do not constitute legal compliance guidance.
