Class 8 (33,001+ lbs GVW) · 80,000 lbs gross combined weight
Tank trucks haul liquids and bulk solids in specialized trailers: petroleum (gasoline, diesel, heating oil), chemical (acids, solvents, industrial liquids), food-grade (milk, juice, edible oils), and dry-bulk (cement, flour, plastics, grain). Each commodity type rates differently because the liability exposure differs dramatically — a tanker leak of motor oil and a tanker leak of corrosive acid produce very different claims. Hazmat-rated tank trucks operate under the federal $5,000,000 liability minimum.
$20,000–$50,000 per year per unit. Food-grade and dry-bulk at the lower end; hazmat chemical and fuel haulers at the higher end, especially with the $5M federal minimum requirement.
If the commodity is hazardous materials (HM) requiring placards, yes — and an additional tank endorsement. For non-hazmat liquids (food-grade, water), just the tank endorsement on the CDL is required.
Pollution liability is a separate coverage line (or endorsement) that pays for cleanup and third-party damages from a spill — soil, water, air. Standard commercial auto liability often excludes pollution events. For tank trucks, pollution coverage is essentially mandatory; most contracts require it explicitly.
Yes, significantly. Food-grade commodities are typically non-hazardous, lower-claim-severity, and less regulated. Chemical and hazmat tanks face higher liability minimums, mandatory pollution coverage, and stricter underwriting. Food-grade rates more like standard trucking; hazmat chemical rates as a specialty class.
