HOS Rules Calculator
Check your available driving hours based on FMCSA hours-of-service rules for property-carrying vehicles.
Operating under the short-haul exemption? If you operate within a 150 air-mile radius and return to your reporting location within 14 hours, you may be exempt from ELD and standard HOS record-keeping requirements. This calculator covers standard rules only — short-haul drivers should consult 49 CFR §395.1(e).
For reference only — always confirm with your ELD
Covers standard 11/14/60/70 property-carrying rules (49 CFR Part 395). Short-haul exception, adverse driving conditions exception, and passenger-carrying rules require manual verification. This tool does not replace your ELD.
