Hours of Service Compliance for Carriers

HOS violations are one of the fastest ways to trigger FMCSA attention. They accumulate quietly, often from issues that have nothing to do with drivers intentionally cheating the system. A log not current here. A missed break there. Supervisors who create pressure to keep moving even when the hours say stop. By the time a carrier notices a problem, the CSA score has already climbed.

We help carriers get their hours of service compliance in order before enforcement makes that decision for them. Our DOT compliance services cover the full range of FMCSA requirements, and HOS is one of the areas we work on most.

Why HOS Compliance Carries More Weight Than Most Carriers Expect

Hours of service violations feed directly into the HOS Compliance BASIC inside the FMCSA’s Compliance, Safety, Accountability program. Most carriers know their CSA scores matter. Fewer know that the HOS Compliance BASIC has an intervention threshold of 65%, lower than most other categories which sit at 80%. That gap is not a technicality. It means a carrier can reach intervention territory faster on HOS issues than on nearly any other compliance area.

What triggers that score isn’t only the obvious violations. Operating over hours carries significant weight in the system. So does a log that isn’t current, a driver without a log when one was required, or a false log. Any violation noted on a roadside inspection report goes into the calculation, regardless of whether a citation was issued. The inspection report itself is what counts. Our federal motor carrier safety regulations page covers how these requirements apply across your operation.

What We See Carriers Get Wrong

In our experience, the violations that push CSA scores into dangerous territory tend to follow predictable patterns. Not necessarily drivers who are trying to run illegal. More often, carriers where HOS was never fully embedded into how the operation actually runs day to day.

The most common issues we find:

• Drivers who received initial HOS training but haven’t had a refresher in years
• Supervisors who understand the regulations on paper but don’t actively enforce them
• Dispatch practices that put drivers in a position where staying legal means missing a load
• Log audits that aren’t happening at all, or are too infrequent to catch patterns before they become violations

ELD adoption has not eliminated these problems. Electronic logging devices record data. They don’t ensure compliance. A driver can still log incorrectly, use personal conveyance improperly, or fail to account for on-duty time accurately, and an ELD will record exactly what the driver entered. Our training and seminars for drivers and supervisors are built around the specific compliance gaps we see in the field, not a generic walkthrough of the regulations.

How We Help Carriers Stay Out of Intervention Territory

Our HOS compliance work covers the areas that actually move the needle. We start with a log audit to establish where things stand. That means reviewing driver records for violation patterns, checking supporting documents against log entries, and identifying gaps in documentation that an FMCSA investigator would flag.

From there, we develop a training plan built around what your drivers and supervisors actually need, not a generic overview of the regulations. If the problem is dispatch pressure, we address that directly. If it’s a supervisor who has quietly been tolerating noncompliance, that has to be dealt with too. Scores don’t improve on their own.

We also work with carriers who have already received a warning letter or who are preparing for a compliance review. If intervention is already in motion, the response needs to be organized and documented. We know how that process works from both sides of the inspection.

What Happens If HOS Violations Keep Accumulating

When a carrier’s HOS Compliance score crosses the intervention threshold, the FMCSA response isn’t fixed. It’s based on how high the score is and how long it’s been elevated. A warning letter is typically the first step. Targeted roadside inspections follow. Further up the scale, carriers face off-site document reviews, on-site investigations, and ultimately compliance reviews that can result in fines or a conditional safety rating.

A conditional or unsatisfactory rating has consequences beyond enforcement. Shippers check safety ratings. Insurance carriers use CSA data in underwriting. A score that’s been elevated for 18 months tells a very specific story about how a carrier is managed, and it’s not one that attracts good freight or favorable rates.

The 24-month window that violations stay in the system means recovery takes time. The only way to move the score down is to accumulate clean inspections and stop adding violations. Getting that process started sooner matters.

Our Background in HOS Enforcement

We spent decades on the enforcement side of commercial trucking before moving to the carrier side. Our founders worked as California Highway Patrol Motor Carrier Specialists. We’ve conducted the inspections. We’ve written the violation reports. We know exactly what investigators look for when they’re reviewing log records and what documentation gaps are most likely to create problems. That same enforcement background informs the way we approach our BIT inspections and audits work as well.

That background shapes how we approach HOS compliance work with carriers. We’re not working from a regulatory handbook. We’re working from experience on both sides of the process.
