Regulation Navigator
Start with the trucking task at hand, read an explanation and find the regulation and official sources.
What are you working on?
Start with a work situation to understand the requirements, common mistakes and next steps.
Driver qualifications
Start with the license, medical status, driver file, and drug and alcohol records to find the rules that fit your situation.
Hours & logs
Compare driving, work, rest, and electronic logs on one timeline. These paths help you research the rules without deciding whether a specific trip is compliant.
Medical certification and fitness
Check whether medical certification is valid and whether a shorter examination interval applies. An unexpired certificate does not automatically authorize driving after a disqualifying injury or illness.
Vehicle & road safety
Compare the condition observed by the driver with the carrier's inspection and maintenance records. Use the related regulation source when reviewing a defect or inspection record.
Registration & taxes
Identify the business activity and where vehicles operate, then check the relevant federal and state records. One number or permit does not represent every filing.
Hiring and driver qualification files
Hiring inquiries, annual reviews and file retention are separate tasks. Track each deadline and supporting record instead of dispatching after collecting only a license.
Drug testing and the Clearinghouse
Pre-employment testing, post-accident testing and Clearinghouse queries have different triggers. Drivers and carriers must check them separately rather than use one as a substitute for another.
Emissions & testing
Identify the specific vehicle and use before opening the official source for testing, fleet, or idling rules. Registration and records for one program do not replace another.
