Hours of Service and Truck Parking

The clock and the parking lot are two different problems

Hours of Service rules answer one question: how long may a driver drive or remain within an applicable duty window?

They do not answer another question that matters just as much at the end of the day: where will that driver actually park?

For most property-carrying drivers subject to the standard federal HOS framework, FMCSA's current Hours of Service summary limits driving to 11 hours after 10 consecutive hours off duty and generally prohibits driving beyond the 14th consecutive hour after coming on duty. Other limits govern breaks, cumulative weekly hours and qualifying sleeper-berth use.

Those rules create a hard operating boundary. Truck-parking availability is a separate infrastructure constraint.

A driver can have time left on the clock and still need to begin looking for parking because the next appropriate location may be miles away, may already be filling up, or may not fit the route at all.

That is where HOS and truck parking collide.

The core HOS rules drivers and fleets plan around

For many property-carrying drivers operating under the standard federal rules, these are the major limits that shape the day. Exceptions and specialized provisions exist, so the current FMCSA rules remain the controlling source for a specific operation.

FMCSA's current Hours of Service guidance should always be checked for the rule, exception or provision that applies to a specific operation.

Why drivers may start looking for parking long before the clock hits zero

A parking search does not begin in a vacuum.

The driver is thinking about traffic ahead, distance to the next parking options, delivery timing, the remaining route and what historically happens at the locations ahead.

That decision can begin well before the legal limit becomes immediate.

Federal truck-parking research has repeatedly documented difficulty finding available parking, particularly at night. FHWA's Jason's Law research describes truck-parking shortages as a national safety concern and reports overcrowding and trucks using unofficial locations such as ramps, shoulders and local streets when designated parking is unavailable.

ATRI's driver parking diaries found that the period from roughly late afternoon through midnight was particularly challenging and documented drivers stopping earlier than they otherwise might in order to secure parking.

That creates a real operating tradeoff:

Keep moving while there is still time available, or stop earlier because the parking options ahead may disappear.

That is not a problem an ELD can solve.

A simple parking-planning scenario

Imagine a driver still has meaningful driving time available.

The route ahead includes three realistic places to stop:

• a location 45 minutes away,
• another roughly 90 minutes beyond that,
• and a final option farther down the route.

The first location is already known to fill quickly in the evening.

The driver now has a decision to make.

Continue toward the second option and preserve more productive driving time?

Or stop earlier because passing the first location increases the risk that the next reasonable option is unavailable too?

The Hours of Service rules define the driver's operating limits.

Parking availability determines which choices actually exist inside those limits.

That is why truck parking is not merely an end-of-day convenience. It is part of route planning.

ELDs record the clock. They do not create a parking space.

Electronic logging devices are central to modern HOS recordkeeping for drivers who are subject to the ELD rule.

FMCSA's ELD guidance says ELDs synchronize with the vehicle and record information such as vehicle motion, miles driven, engine hours, identification information and duty status. Drivers use those records to document and certify their duty status, and enforcement officials can review ELD records for HOS compliance.

That is what the device is built to do.

It can document:

• driving time,
• on-duty time,
• off-duty time,
• sleeper-berth status,
• vehicle movement,
• and other required record information.

It cannot make a full truck stop suddenly have another space.

It cannot tell a region to build more parking.

And it cannot replace the operational judgment required to decide where a driver should reasonably plan to end the driving day.

For fleets, that distinction matters.

HOS compliance is partly a recordkeeping and operating discipline. Parking availability is an infrastructure and planning problem sitting beside it.

For carriers that want a deeper explanation of the HOS framework, log review, ELD limits and the operational work behind compliance, Fleet Regulators' plain-English HOS compliance guide goes deeper on the carrier side.

The 14-hour window makes bad parking assumptions expensive

One of the most important HOS concepts for trip planning is the 14-hour window.

For drivers operating under the standard property-carrying rules, FMCSA's current Hours of Service summary generally prohibits driving beyond the 14th consecutive hour after coming on duty following 10 consecutive hours off duty. Ordinary off-duty time during the day does not simply stop that clock.

That means a parking assumption such as:

“There should be something farther down the road.”

is not much of a plan.

Every additional mile toward the next location consumes time and reduces the driver's available alternatives.

A stronger parking plan considers:

• where parking is reasonably available,
• when those locations tend to become difficult,
• whether the route has backup options,
• how much time is required to reach them,
• and whether the driver's remaining HOS supports the plan.

The goal is not to squeeze every possible minute from the clock.

The goal is to avoid making the end of the day dependent on luck.

The 34-hour restart changes what parking can mean

A short parking stop and a 34-hour off-duty period are not the same experience.

FMCSA's current Hours of Service summary allows qualifying drivers to restart the applicable 60/70-hour calculation after taking at least 34 consecutive hours off duty.

Thirty-four hours is more than a place to put a tractor and trailer.

For the driver, it can mean spending a significant part of two days away from home in the same location.

That is where the conversation starts moving beyond parking capacity alone.

A driver may also be thinking about:

• rest,
• food,
• restroom access,
• personal hygiene,
• privacy,
• movement after hours in the seat,
• communication with family,
• and being ready for the next driving period.

Those are human needs, not HOS rules.

But they are part of the reality surrounding longer off-duty periods.

That distinction is central to The Driver Reset, ALL SET's approach to thinking about the driver's experience after the parking brake is set.

Sleeper-berth flexibility changes timing, not geography

The sleeper-berth provisions give qualifying drivers some flexibility in how required off-duty periods may be divided.

Under FMCSA's current rules, a qualifying split can include at least 7 consecutive hours in the sleeper berth combined with another qualifying off-duty period of at least 2 hours, with the periods totaling at least 10 hours. When properly paired, those qualifying periods are treated differently in calculating the 14-hour window.

That flexibility can affect how a driver's day is structured.

But the geography does not change.

The driver still needs an appropriate place for the truck during the off-duty period.

A regulation can define when rest qualifies.

It cannot guarantee that the needed parking exists where the driver needs it.

What fleets can do before parking becomes a clock problem

Parking availability is not completely within a carrier's control.

Parking planning is.

A practical fleet approach can include:

1. Treat parking as part of route planning
   Do not wait until the final hour of the driving day to think about where the truck will stop.
2. Identify more than one realistic option
   A primary location without a backup is fragile planning when parking demand is high.
3. Learn the recurring lanes
   Drivers running the same corridors often know which locations become difficult and at what times. That information is useful operational data.
4. Listen to driver feedback
   A parking plan that works on paper may not work at 8:30 p.m. on a Tuesday. Drivers see the actual conditions.
5. Separate HOS management from parking availability
   An ELD can help document HOS. It cannot solve parking supply. Treat both issues intentionally.
6. Verify the rules that apply to the operation
   Short-haul, adverse-driving-condition, sleeper-berth and other provisions can have specific requirements. Use current FMCSA guidance and qualified compliance support rather than assumptions.

Why more truck-parking infrastructure still matters

Better trip planning helps.

It does not manufacture additional spaces.

FHWA's Jason's Law research has documented truck-parking shortages across the country and the connection between freight corridors, driver rest requirements and parking demand. The agency's research notes that parking demand reflects both regulatory requirements and the logistics patterns created by freight movement.

More recent ATRI research continues to describe truck parking as a persistent industry issue. In 2025, ATRI cited an estimate of roughly one truck-parking space nationally for every 11 truck drivers while examining ways states could expand public parking capacity.

Planning matters.

Information matters.

Better parking-availability tools matter.

But eventually, a parking shortage also requires more useful parking capacity in the places freight actually moves.

That is the infrastructure problem ALL SET Truck Park is being built to address.

Parking the truck is only the first problem

HOS discussions naturally focus on time.

Drivers experience the problem as time plus place.

Where can I stop?

How far away is it?

Will there still be room?

Can I reasonably spend my off-duty time there?

What happens if the next option is full?

Those questions sit at the intersection of regulation, infrastructure and the lived reality of moving freight.

ALL SET's role is not to rewrite Hours of Service rules.

It is to help build a better answer to the parking side of the equation.

Quick reference checklist

Before the end of a driving period, a parking plan should answer:

• Where is the intended stopping location?
• What is the backup if that location is unavailable?
• How much driving time is required to reach each option?
• Does the route realistically fit the driver's available HOS?
• Is the parking appropriate for the truck and operating situation?
• Is a longer off-duty period or 34-hour restart being planned?
• Has the driver reported recurring parking problems on this lane?
• Does the fleet have enough information to improve the next trip?

The exact HOS requirements for a specific driver or operation should always be confirmed against current FMCSA regulations and guidance.
