What Truck Insurance Costs
for Septic Fleets.
Commercial auto is rated one truck at a time, on filed variables you can actually look up. Here is the structure, with real published factors.
We shop your septic business with carriers like
What we review on a fleet
Unit by unit, because that is how it is rated.
Each vehicle’s size, use and radius classification
Against what the truck actually does, not what it did when the policy was written.
Which secondary classification is being applied
Waste disposal and contractors pull in opposite directions, and the filed rule applies the highest-rated one where several could apply.
Whether the covered auto symbols pick up new vehicles
Because buying trucks mid-season is normal in this trade and the gap is invisible until a claim.
Whether the pollution endorsement is on the policy
A cheaper auto quote that excludes your load is not a cheaper policy.
The Septic Cleaning Insurance Group Policy Review
We read the whole policy
Before we quote anything we read what you already have, cover to cover, and tell you plainly what it does and does not do.
We map your actual operation
Pumping, installation, hauling, grease trap, portable units: each one underwrites differently. We classify what you really do, not a generic contractor code.
We shop carriers who understand septic risk
Standard markets when they fit, specialty and E&S markets when they do not. If a carrier does not understand pollution exposure, we do not use them.
We explain the quote in plain language
You get the number, the limits, the exclusions that matter, and the reasoning. No pass-through, no blind binding.
Why working from filed factors beats shopping on price
You can see which lever moved
If a renewal jumps, the structure tells you whether it was a classification change, a radius change, a driver record, or the carrier’s own filing.
Some of the levers are operational
Radius and use class track how you actually run the business, which means they are changeable in a way a market average is not.
It exposes the false saving
Dropping a limit or an endorsement on the heaviest thing you own is the worst possible place to economise.
And it keeps the conversation honest
Every factor on this page is published and linked. You can check us.
Three filed variables decide most of each unit’s price
Commercial auto is rated per power unit. Each truck carries its own size, use and radius classification, and the factors multiply.
Size, by gross vehicle weight
Filed definitions put light at 10,000 pounds or less, medium at 10,001 to 20,000, heavy at 20,001 to 45,000, and extra heavy above 45,000. A loaded vacuum tanker is usually heavy or extra heavy. Your service pickup is light.
Use, which is where septage haulers get reclassified
Service use means transporting “the insured’s personnel, tools, equipment, and incidental supplies to or from a job location… principally parked at job locations for the majority of the working day.” Commercial use covers vehicles “used for transporting property” that are not service or retail, and the manual adds that “if service or retail use does not apply, rate as commercial use.” A truck carrying a load of septage to a plant is transporting property.
Radius, measured from where the truck is garaged
Local is 50 miles or less, intermediate 51 to 200, long distance beyond that, measured straight-line from the principal garaging address. A distant disposal site can quietly move a truck out of the local band.
And if a truck does several things, the highest class applies
The filed multi-use rule applies the highest-rated classification unless 80 percent of use falls in a lower-rated activity. Occasional hauling does not get averaged away.

What the multipliers actually look like
These are filed liability and property damage rating factors from one state’s residual market manual. They are not a national rate and your carrier’s own filed factors will differ, but the structure is standard and it shows you exactly how the gap between a pickup and a tanker opens up.
- Light truck, service use, local radius: 1.00 — the baseline. This is your tool pickup
- Light service intermediate 1.15 · long distance 1.25
- Heavy truck, service use, local: 1.10 · intermediate 1.30
- Heavy truck, commercial use, local 1.45 · intermediate 1.75
- Extra heavy, local 2.00 · intermediate 2.60
- Heavy truck-tractor, commercial, local 1.80 · intermediate 2.20
- Semitrailers and trailers 0.10 to 0.15 · service or utility trailers at 2,000 lbs or under: 0.00
- Secondary classification 5, Waste Disposal: +0.30. It covers “autos transporting salvage and waste material for disposal or resale”
- Secondary classification 8, Contractors other than dump trucks: −0.05
- So a pump truck classed as waste disposal and an installer’s service pickup sit on opposite sides of that secondary adjustment, a 0.35 spread before the primary factor is even applied
- Where more than one secondary classification applies, the filed rule uses the highest-rated one
Worked through: a local light service pickup sits at 1.00 with a contractor credit of −0.05. An extra heavy tanker on an intermediate radius sits at 2.60 with a waste disposal load of +0.30. That is not an opinion about tankers being expensive; it is the filed arithmetic.

The closest thing to a real published number
We will not quote you an industry average, because no credible one exists for this trade. What does exist is a carrier publishing figures from its own book, with the basis stated.
Contractors, $260 per month per power unit
Progressive Commercial publishes 2025 figures on the stated basis of “new policy premium per power unit for liability and physical damage coverage for policies with no driver violations.” Its business auto figure is $276, tow trucks $606, for-hire specialty trucks $734, and for-hire transport trucks $926.
Read what that number is before you use it
It is per power unit, it is a new policy figure, it covers liability and physical damage, and it assumes no driver violations. Change any of those and it stops applying to you.
And note there is no septic category in it
“Contractors” is a broad bucket. A septage tanker rated as waste disposal on an intermediate radius is not the average contractor vehicle, and we would not represent that figure as a septic number.
Which is exactly why we work from the filed factors instead
Published carrier averages tell you what somebody else paid. The filed classification structure tells you what moves your number, and which of those you can change.
Underwriters who’ve actually walked a septic job site
Septic Cleaning Insurance Group
We built this agency around one gap we kept seeing: big-box commercial insurers write septic contractor policies the same way they write policies for any other trade, missing the environmental and pollution exposure that actually matters in this business. Our team goes deep on septic-specific risk before recommending coverage, maintains relationships with carriers who understand pumping, installation, and disposal operations specifically, and keeps specialty and E&S markets in reserve for the accounts standard carriers will not touch.
Straight answers, no insurance-speak
Three filed variables stack against it. Weight class puts a loaded tanker in heavy or extra heavy rather than light. Use class arguably makes it commercial rather than service, because it is transporting property rather than carrying your tools. And a distant disposal site can push it out of the local radius band. In one state’s filed residual market manual a local light service truck sits at 1.00 while an extra heavy unit on an intermediate radius sits at 2.60.
It is a filed secondary classification covering autos transporting salvage and waste material for disposal or resale, and in the manual we reference it adds 0.30 to the rating factor. By contrast the contractors secondary classification, other than dump trucks, subtracts 0.05. Which side of that line a given truck falls on is worth getting right.
No credible published one. Progressive publishes $260 per month per power unit for contractors on a 2025 new policy basis for liability and physical damage with no driver violations, but contractors is a broad bucket and there is no septic category in it. We would rather show you the filed factors that move your number than quote an average that does not describe your trucks.
The premium is pro-rated either way. What matters more is whether your policy’s covered auto symbols pick the new truck up automatically. On some symbols a newly acquired vehicle is covered; on others it is not covered until it is scheduled. That is explained on the commercial auto coverage page.
It can, because radius is a filed rating variable with real steps in it. Moving from intermediate back to local is a genuine factor change rather than a rounding difference. Whether a nearer receiving site is operationally realistic is a separate question, but the premium effect is real.
It usually is. In the filed manual we reference, semitrailers and trailers carry factors of 0.10 to 0.15, and service or utility trailers at 2,000 pounds or under carry 0.00. Trailers are genuinely cheap. The power units are where the premium sits.
Yes, and the carrier figure above states its own assumption of no driver violations, which tells you how much that assumption is doing. Driver vetting and MVR monitoring are among the few things on this line you control directly.
It is one of the levers, and on physical damage for older units it can be sensible. What we would not do is lower your liability limit to save premium on a vehicle that weighs what a loaded tanker weighs. The severity potential there is the reason the limit exists.
