The business auto insurance policy does not provide coverage for pollution from your cargo – paint, solvents, bulk chemicals or other hazardous materials. Spilling these chemicals, even in an auto accident, is not covered. Most policies will only pay pollution cleanup expense for chemicals and fluids that are used as part of the vehicles engine – the oil in the crankcase, gas in your tank, transmission fluid, etc.
Separate pollution liability policies are available. Talk with your insurance adviser.
