49 CFR Part 395: Hours of service
Find hours-of-service rules, official CFR sections, ELD questions, and source-checked guides to the driving limits and 30-minute break.
Start with the controlling source
- 49 CFR Part 395 — Official regulation
- 49 CFR 395.1 — Scope and exceptions
- 49 CFR 395.3 — Property-carrying driving limits
- 49 CFR 395.8 — Records of duty status
Read the current section, its scope and exceptions, and applicable agency guidance. A citation identifies a rule; it does not establish that the rule applies to your operation.
Before you ask
- Identify whether the operation carries property or passengers.
- Have the recent driving, on-duty, off-duty, and sleeper-berth periods available.
- Identify the specific exception or state rule you are asking about.
Questions and guides
Source-checked overviews are identified separately from generated guidance that still needs source review.
