What is in the tank sets your federal minimum, not your revenue.

Commercial auto

Vehicles the business owns and the people who drive them for work.

Without it — The filing that keeps your authority active, at the higher minimum your commodity requires rather than the general freight figure.

Contractors pollution liability

Bodily injury, property damage and clean-up caused by a pollutant your work released: chemical drift, run-off, fuel spills. The standard general liability form excludes all of it.

Without it — A rollover that releases product is a clean-up bill owed to a regulator, and standard liability wording excludes it.

Motor truck cargo

The freight itself while you are hauling it. Separate from the liability on the truck.

Without it — A load of product lost in an incident is money owed to the shipper immediately.

Auto physical damage

Damage to your own tractor and trailer. Primary liability pays for what you do to everyone else and nothing for your equipment, so without this a rollover you caused leaves you paying off a truck you can no longer run.

Without it — Tank trailers are expensive and a rollover usually totals one.

Umbrella & excess liability

Extra limit stacked above general liability, auto and employers liability. Usually the cheapest million dollars on the policy.

Without it — Tanker losses combine bodily injury, property damage and remediation in a single event, which is how primary limits disappear.

Workers compensation

Required in almost every state the moment you have employees. Priced on payroll and class code, which is why the class code is worth arguing about.

Without it — Loading and unloading is where tanker injuries concentrate, not the driving.

Truckers general liability

General liability written for a motor carrier: the yard, the dock, loading and customer premises. The auto policy answers for the vehicle; this answers for everything else.

Without it — Yards, docks, loading and customer premises sit outside the auto policy entirely, and brokers ask for general liability by name.

What is my federal minimum if I haul hazmat?

It depends on the commodity, not on your size. General freight carriers sit at $750,000. Oil and most hazardous materials require $1,000,000, and the highest-hazard commodities — certain explosives, poison-inhalation-hazard gases and highway-route-controlled radioactive material — require $5,000,000. Bulk hazardous shipments in large cargo tanks fall into the $5,000,000 band as well. Getting this wrong is not a pricing error, it is an authority problem.

Is pollution really not covered by my liability policy?

Generally not. Auto liability policies carry pollution exclusions, and the MCS-90 endorsement is a public guarantee rather than coverage for you, where it pays a claim your policy excluded, the insurer can come back to you for the money. Clean-up cost after a release is the exposure that needs its own answer.

Does an empty tank still count as hazmat?

A tank with residue is treated very differently from a clean one, and the placarding rules follow the residue. This matters for insurance because your filing and your rating are based on what you are authorized and equipped to haul, not solely on what is in the tank today.

What does a tanker and hazmat hauling insurance application ask for?

The applications for tanker and hazmat hauling businesses ask about 4 things above all: what commodities do you haul; do you haul full truckloads or less than truckload; are your vehicles equipped with gps, cameras, or other tracking devices; list all losses and accidents from the last three years. Have your vehicle information including year, make, model, and current value for each truck and trailer and three years of loss runs from your current and prior insurance companies ready and a quote takes a day instead of a week.
