This is a simple estimate for the standard 11/14/70 rule and doesn't account for the 30-minute break requirement, sleeper berth splits, adverse conditions, or short-haul exceptions. Always follow your ELD and FMCSA's actual Hours of Service rules - this tool is a quick reference, not a compliance record.
