Hours-of-service math: stop scheduling impossible pickup windows
A practical guide for brokers on how driver HOS interacts with the pickup window you set.
The basic math
A driver has 11 driving hours and a 14-hour duty window per day. After a 10-hour reset, they're fresh. But if your pickup is at hour 9 of their duty window, you have at most 5 driving hours before they're out of clock — and they need to find a safe parking spot.
The mistake we keep seeing
Brokers schedule a 2-hour pickup window starting now, on a lane that's 4 hours from the driver. The driver shows up tired, fights for parking, and either runs over hours (illegal) or sleeps in a Walmart lot (unsafe and Bad Vibes).
The fix
Use a simple rule: "available driving hours minus 1.5 hours" is the maximum lane length you should book on a same-day pickup. Anything longer, set the pickup tomorrow. Drivers won't refuse the load — they'll refuse the broker.
