A hazmat dispatch service that plans where you can stop, not just where you're going

Hazmat and tanker freight pays for the endorsements, the paperwork and the care it takes, and it comes with rules that general freight never thinks about. Where you can park. When the truck has to be attended. How you fuel. Hours of service still apply on top of all of it. Our hazmat dispatchers plan every break, fuel stop and overnight around those rules before the load reaches your phone, and every load still comes to you as a rate confirmation for your yes or no.

Hazmat and tanker rates: what the public data does and doesn't show

There's no public national spot index for tanker or hazmat freight the way there is for dry van, reefer and flatbed. Most bulk liquid and hazmat freight moves on contracts and dedicated lanes, and spot rates vary widely by product, tank type, region and season. Anyone quoting you a national average hazmat rate per mile is guessing.

What is published and dated is the cost side. The American Transportation Research Institute's Analysis of the Operational Costs of Trucking, released July 15, 2026, put the industry-average cost to operate a truck in 2025 at $2.336 per mile, or $1.854 per mile excluding fuel. The same report found tank carriers running an average operating margin of about 4.0 percent in 2025, compared with under 1 percent for truckload and refrigerated carriers.

For you, that means two things. Your floor rate starts with your own cost per mile, which is often above the industry average once hazmat insurance, endorsements and tank cleaning are in. And hazmat work has historically held margin better than general freight, which is a good reason to price it carefully instead of chasing volume. We counter every hazmat load against your real costs and the extra time the rules take.

BOARD 03HAZMAT STOP PLANNER

The hazmat stop planner: every stop on the trip has rules

Below is an EXAMPLE trip with five stops. Tap a stop to see the Part 397 rules that apply there, and switch between general hazmat (fuel, chemicals, gases) and explosives in Divisions 1.1 to 1.3, where the rules get much stricter. Every rule is tagged with its citation.

30-MIN BREAK · RULES THAT APPLY

  • Not parked on or within 5 feet of the traveled road, except briefly when there's no alternative.§ 397.7(b)
  • On a public road or shoulder, the vehicle must be attended: driver on the vehicle and awake (not in the sleeper), or within 100 feet with a clear view.§ 397.5(c)-(d)
  • Attending the vehicle still counts: the break can be on duty, not driving.§ 395.3(a)(3)(ii)

Rules from 49 CFR Part 397 and the HOS rules in Part 395, checked 2026-10-05. States and local authorities can add routing and parking restrictions. Planning aid only; not legal advice.

This is why a hazmat break can't be planned like a dry van break. A 30-minute stop on a highway shoulder is fine for general freight; for a placarded load it has to be off the traveled lane and the truck has to be attended. An overnight for explosives needs a safe haven or someone qualified to stay with the truck. We plan those locations before the clock runs out, not after.

BOARD 04SAME CLOCK, MORE RULES

Do hazmat drivers have different hours of service rules?

No. Hazmat and tanker drivers follow the same hours of service limits as other property carriers: 11 hours of driving inside a 14-hour window, a 30-minute break after 8 hours of driving, 10 hours off between shifts, and the 60/70-hour cycle (49 CFR 395.3). What changes is everything around those limits: where the break can happen, whether the truck must be attended during it, and where you can take your 10 hours.

One detail helps. The 30-minute break can be any non-driving period, including on duty not driving, so time spent attending a parked hazmat truck still counts as your break. What doesn't help is a plan that leaves you out of hours with no legal place to park a placarded load. That's the planning failure we're built to prevent. HOS rules for hazmat

BOARD 05WHAT YOU NEED

What you need to haul hazmat and tanker loads

CDL endorsements

H for hazardous materials, N for tank vehicles, or X for both. The H endorsement requires a TSA security threat assessment.

PHMSA registration

Carriers hauling placarded quantities generally must register with PHMSA every year (49 CFR Part 107, subpart G).

Higher insurance minimums

Federal financial responsibility minimums for hazmat run from $1 million to $5 million depending on the material (49 CFR 387.9).

Safety permit for some materials

Certain high-hazard materials need an FMCSA Hazardous Materials Safety Permit, which requires a satisfactory safety record (49 CFR Part 385, subpart E).

Security plan

Carriers of certain hazmat quantities need a written security plan (49 CFR Part 172, subpart I).

This list is a starting point, not legal advice. Your materials and your operation decide which rules apply, so confirm each one against the regulation. Studying for the H or N endorsement? Try the CDL endorsement practice quiz.

BOARD 06TANKER LOADS

Tanker loads take their own planning

Liquid loads move. A partly filled tank surges forward when you brake and pushes back when you accelerate, so tanker driving is slower and more careful, and transit times need to reflect that. Tank cleaning between incompatible products, wash-out certificates, and loading and unloading at plants with their own safety rules all add on-duty time to the day.

We plan tanker loads with those hours counted: wash times, plant check-in and safety briefings, loading and pump-off times, and realistic driving speeds. If a load's appointment only works if you skip the wash or rush the unload, it doesn't reach you.

We also track product compatibility. The next load has to be safe and acceptable to haul after the last one, which can mean a full wash, a specific cleaning certificate, or a dedicated tank for some products. We ask about your tank's last load and wash status before we offer the next one, so a good rate never turns into a rejected tank at the plant gate.

BOARD 07THE OVERNIGHT

Finding a legal overnight is part of the load

Truck parking is tight for everyone, and tighter for placarded loads. Some truck stops limit or prohibit hazmat parking, some only allow it in certain rows, and a load of explosives needs either a safe haven or someone qualified to stay with the truck. When the 14-hour window is running out, a driver with a placarded load has fewer choices than anyone else on the road.

So the overnight gets chosen when the load is booked, not at 19:00. We look at the route, the appointment and your hours, pick a location where the parking and attendance rules can be met, and leave slack in case the day runs long. If no legal overnight fits the schedule, the schedule changes, or the load doesn't reach you.

BOARD 08A TANKER WEEK

A tanker week, planned around the rules

EXAMPLE, one owner-operator with a stainless tanker and an X endorsement, based near Baton Rouge. Monday: a chemical load from a plant along the river, with a 90-minute safety check-in and loading time planned in, and the overnight chosen at booking. Tuesday: delivery in the morning, then a wash at an approved rack before the next product. Wednesday: a food-grade liquid load that needed a kosher wash certificate, confirmed with the shipper the day before. Thursday: a fuel additive run with a fuel stop planned at a location where the engine-off and attended-nozzle rules were easy to follow. Friday: an empty return to the base, still placarded for the residue, parked by the same rules. Every load reached the driver as a rate confirmation first.

Hazmat dispatch fits owner-operators and small fleets with H, N or X endorsements who want breaks, fuel and overnights planned with the rules in mind, and rates negotiated for the real cost of the work. If your hazmat freight is already fully dedicated with fixed routes, a desk adds less; we'll say so. Every load still comes to you as a rate confirmation first, and declining one costs nothing.

Shipping papers and emergency response information confirmed with the shipper before pickup.

Rates for the risk

Every load countered against your real costs, including hazmat insurance and cleaning.
BOARD 10FEE & FAQ

What hazmat dispatch costs

Hazmat doesn't change the fee. One truck with authority older than 6 months pays 5% of gross, 7% while your MC is under 6 months, and fleets of 2 or more trucks pay the 4% fleet rate while it lasts. No setup fee, no minimums, month to month, and nothing on a week you don't haul. Full pricing

No. The same limits apply: 11 hours of driving, a 14-hour window, a 30-minute break after 8 hours of driving and 10 hours off (49 CFR 395.3). Hazmat adds Part 397 rules about where you park and when the truck must be attended, which shape where breaks and overnights can happen.
