What is a Tank Vehicles Endorsement?

Tank Vehicles focuses on liquid or gaseous cargo and how surge affects braking, turning, and stability.

Who should get the Tank Vehicles

Drivers hauling liquid or gaseous cargo in tanks.

Topics Covered for Tank Vehicles

Liquid Surge

Liquids in partially-filled tanks shift when accelerating, braking, or turning, creating surge forces that directly affect vehicle control. The exam tests how to anticipate surge and adjust driving technique to compensate.

Rollover Prevention

Tank vehicles have a high center of gravity, making them especially vulnerable to rollover on curves, ramps, and during lane changes. You will study speed thresholds, weight distribution, and safe cornering technique.

Tank Vehicle Inspections

Tank inspections require checking for leaks, inspecting valves and vents, and verifying the tank is properly secured to the chassis. Each step has test-specific requirements beyond the standard pre-trip inspection.

Safe Driving Adjustments

Driving a tank vehicle requires increased following distance, slower turns, and gentler braking compared to standard freight. The test covers the specific adjustments tank operators must make in all road conditions.

Tank and Cargo Types

Different tank designs, including baffled, unbaffled, and pressurized, behave differently in motion and require different driving adjustments. Understanding tank construction and its effect on handling is a major exam topic.
