Hauling terms
Crude hauler
By Mike Shelton · Updated · How we check facts
Crude hauler: A crude hauler is a tanker driver who picks up crude oil from storage tanks at well sites and hauls it to pipeline stations, rail terminals or refineries. Crude is a Class 3 flammable liquid, so the work needs a CDL with tank and hazmat endorsements. 49 CFR 172.101 Hazardous Materials TableChecked October 2026
What the job involves
Most crude hauling is short and repetitive: a loop between well-site tank batteries and a nearby station, several times a day. At the well site the driver gauges the tank, measures the oil, takes samples, loads through a hose and records the run on a ticket. At the station the load is measured again and unloaded. Roads to the wells are often unpaved and rough, and work runs around the clock in busy fields.
The hazmat side
Petroleum crude oil is UN1267 in the Hazardous Materials Table, a Class 3 flammable liquid. 49 CFR 172.101 Hazardous Materials TableChecked October 2026 In a cargo tank it is a bulk load, placarded FLAMMABLE with the number displayed. Drivers need the X endorsement, or N and H, and the hazmat endorsement needs a TSA security threat assessment. 49 CFR 383.141Checked October 2026
In practice EXAMPLE
A crude hauler starts the shift at 5:00, runs five loads from three tank batteries to a pipeline station 30 miles away, and logs each run on a field ticket. On wet days the lease roads slow every trip. Because crude is heavy, the truck scales out under 80,000 lb well before the tank is full, which the weight limit checker helps confirm. More in our hauling guide.
Hours, roads and pay
Crude hauling is often local or regional, with many short loaded trips a day, so drivers spend much of the shift loading, gauging and unloading rather than driving. Lease roads can be rough, muddy or icy, and many sites run around the clock. Pay is commonly per load, per hour or per barrel, set by the carrier or the producer. Demand follows drilling and production in each field, so work can be very busy for a season and slower the next.
Many crude carriers hire drivers with tanker experience, and new drivers often start by riding along to learn gauging, sampling and the paperwork each producer and station expects.
Questions
01Do crude haulers need a hazmat endorsement?
Yes. Crude oil is a Class 3 hazardous material, and hauling it in a cargo tank requires placards, which means the driver needs a CDL with the hazmat endorsement plus the tank endorsement, or the combined X endorsement. The hazmat endorsement requires a TSA security threat assessment before the state can issue it.
