Oilfield Hours-of-Service Rules Explained

Permian DOT Compliance · Regulatory Guide

Most FMCSA hours-of-service violations we see in the Permian Basin don't come from drivers ignoring the rules — they come from fleets applying the standard commercial trucking rules to oilfield drivers, who actually operate under a different set. Get this wrong and it shows up on your CSA score fast. Here's what's actually different.

The 24-hour restart provision

Standard commercial drivers need a 34-hour restart to reset their weekly hours. Drivers hauling exclusively for oil and gas operations get a 24-hour restart instead — a real, FMCSA-recognized exception, not a workaround. It exists because oilfield work genuinely runs on a different rhythm than long-haul freight: shorter, more frequent hauls between a yard and a well site, often with unpredictable wait times at the location itself.

On-duty time at the well site

Wait time at a well site can count differently than wait time on the road, depending on whether the driver is relieved of responsibility for the vehicle. This is one of the most commonly mis-logged categories we find during a driver file review — drivers and dispatchers often log wait time inconsistently across the same fleet, which is exactly the kind of inconsistency an FMCSA auditor looks for first.

Why this matters more in the Permian Basin specifically

Texas DPS has run commercial motor vehicle safety enforcement operations specifically targeting this region, given the volume and pace of oilfield truck traffic here. That means the odds of a roadside inspection catching an hours-of-service logging error are meaningfully higher here than in a lower-traffic market — and a logging error caught at roadside becomes a CSA violation that stays on your record for 24 months.

What a correct setup looks like

• Clear documentation of which drivers and loads qualify for the 24-hour restart, updated whenever assignments change
• Consistent on-duty/wait-time logging standards across every driver, not left to individual interpretation
• A regular internal audit — quarterly, not just when a DOT letter arrives — catching drift before an inspector does
