Federal hours-of-service rules cap what a driver can legally do in a day, and electronic logging devices make those caps non-negotiable, which is why a Miami delivery appointment that looks reasonable on paper can be impossible in practice. A driver has an 11-hour driving limit inside a 14-hour on-duty window, and once that 14-hour clock starts it does not pause for your dock. Understanding this changes how you schedule, and it explains most detention disputes.
The rules that matter for local and regional freight
The 11-hour driving limit
A property-carrying driver may drive up to 11 hours after 10 consecutive hours off duty. This is the one most shippers know about, and it is rarely the binding constraint on South Florida deliveries.
The 14-hour window
This is the constraint that actually bites. Once the driver goes on duty, they have 14 consecutive hours in which driving is permitted. Loading, waiting, fueling, inspections and lunch all consume that window even though none of them is driving. A driver who spends three hours waiting at a Medley dock has three fewer hours to complete the day, and no amount of goodwill resets the clock.
The 30-minute break
After eight cumulative hours of driving time, a driver needs a 30-minute interruption of driving status. That break has to land somewhere, and in Miami-Dade finding legal truck parking to take it is genuinely difficult, as our post on Miami-Dade truck routes and parking rules describes.
Weekly limits
Drivers are limited to 60 hours on duty in seven consecutive days or 70 in eight, depending on the carrier’s operating schedule, with a 34-hour restart available. For a dedicated route this means late-week capacity is tighter than early-week capacity.
The short-haul exception
Drivers who stay within a 150 air-mile radius of their reporting location and return within 14 hours can operate under a short-haul exception without an ELD record of duty status. A large share of South Florida local delivery and port drayage work fits inside this radius, which is one reason local operations look different from long-haul ones.
What ELDs changed
Before electronic logs, a driver could stretch a day and reconcile the paperwork later. ELDs record duty status automatically and make that impossible. The practical effect for shippers is that carriers now decline appointments they would once have accepted, and detention has real consequences: an hour lost at your dock is an hour of legally unavailable capacity, not just an inconvenience.
How this shapes Miami delivery windows
- Early appointments are worth more. A 7 a.m. slot leaves a driver a usable day. A 2 p.m. slot may consume their remaining window entirely.
- Port queues eat the clock. A drayage driver waiting in a terminal line is burning the 14-hour window. This is why pre-pulls and yard storage are so valuable in South Florida, and why street turns matter.
- Rush hour is a hard constraint. I-95, the Palmetto and the Dolphin at peak add real time to every leg. A route that fits at 10 a.m. does not fit at 5 p.m.
- Detention is a capacity problem, not just a fee. Charging detention compensates the carrier but does not give the driver their hours back, which is why chronically slow docks lose carrier coverage. We cover the fee side in our post on detention, layover and TONU charges.
Practical scheduling advice
Give carriers a window rather than a fixed minute where you can, and honor first-come-first-served if you promise it. Have paperwork ready before the truck arrives. If you run a facility with unpredictable dwell, consider drop-trailer service so the driver is not tied to your dock at all, an option we compare in our post on drop trailer versus live load. And when you are quoting a same-day multi-stop route, count the stops against the 14-hour window rather than against the driving hours.
Frequently asked questions
Does waiting at my dock count against a driver’s hours?
Yes. Time spent waiting or loading is on-duty time and consumes the 14-hour window even though it is not driving time. That window cannot be paused or extended, so dwell at your facility directly reduces how much of the route the driver can legally complete that day.
Do local Miami delivery drivers need an ELD?
Not always. Drivers operating within a 150 air-mile radius of their reporting location who return within 14 hours may use the short-haul exception and are not required to keep an ELD record of duty status. Much South Florida local delivery and port drayage work falls inside that radius.
Why did my carrier refuse a late-afternoon appointment?
Most likely the appointment did not fit inside the driver’s remaining 14-hour window once queue time, traffic and the return leg were counted. Offering an earlier slot, a wider window, or drop-trailer service usually solves it.
