ELD Clocks Keep Running During Events Drivers Cannot Control

Electronic Logging Devices rigidly track a driver's 14-hour on-duty window from the moment they go on-duty, and that clock never pauses — not for traffic jams, not for 3-hour detention at a shipper, not for weather delays, not for a breakdown waiting on roadside assistance. Once 14 hours elapse, the driver must stop regardless of whether they actually drove for 11 hours or sat idle for most of the day. Before the ELD mandate (fully enforced 2019), paper logs allowed drivers some flexibility to account for unproductive time. Now, a driver who spends 4 hours in detention and 2 hours in traffic has only 8 hours of their 14-hour window remaining, but may have driven as few as 2 hours. They cannot legally drive the remaining 6 hours they are physically capable of because the clock has expired. This means the driver loses an entire day's worth of miles — and income — through no fault of their own. The structural root cause is that the HOS rules were designed around a continuous-duty model that assumes a driver is either working or resting, with no concept of 'waiting' as a distinct, non-fatiguing state. FMCSA has acknowledged driver frustrations and in 2025 signaled 'common sense' reforms may be coming, but no rule changes have been implemented.
