The clock inside the truck

For most long-haul property drivers the core limits, in plain numbers, are these. After 10 hours off duty, a driver may drive up to 11 hours, but only inside a 14-hour window that starts when they come on duty. They must take a 30-minute break after 8 hours of driving. Across a week they cannot exceed 60 hours on duty in 7 days, or 70 hours in 8 days, unless they take a 34-hour restart that zeros that weekly clock. There are short-haul exceptions and special cases for bad weather and split sleep. The shape of the rule is the part to remember: driving time and the length of the workday are both limited.

Why the ELD exists

Paper logs were easy to falsify and easy to demand. A shipper or a dispatcher could pressure a driver to “make it work,” and the logbook would agree. The ELD takes the driving record from the truck. It does not make the driver honest about every on-duty minute at a dock, and inspectors still find unassigned driving and devices that are not really certified. It did remove the most casual version of the lie.

When a driver runs out of hours, the freight waits. That is the rule working, not a driver being difficult. A warehouse that burns three hours loading a truck can push a legal trip into an illegal one. Detention — sitting unpaid while a dock runs late — is how a shipper accidentally creates an hours violation and then complains about a late delivery the next morning.
