Why is tanker truck insurance so expensive?

Tanker Truck insurance costs are driven by liability exposure, cargo value, driver experience, and operating radius. Commercial trucking has higher liability limits than personal auto (typically $750K-$1M vs. $100K), and rising nuclear verdicts have pushed premiums industry-wide.
