Tanker Vehicle Inspection and Pre-Trip Checks
Tanker inspection is where the Georgia CDL Tanker Test separates a general pre-trip from a cargo-tank pre-trip. The examiner expects you to find tank-specific defects before the vehicle moves, not just tractor lights and tires.
Check the tank as a system
Inspect the shell, piping, flanges, valves, vents, and hoses for wet spots, drips, stains, corrosion, cracks, and loose clamps. A leak may show only as a dark streak or odor. Confirm dome covers and hatches are closed and sealed, vents are clear, discharge outlets are capped, and valves are in the correct position for travel. Check tank mounts, straps, bolts, and bulkheads for security. Placards and cargo-tank markings must match the cargo. Tires, brakes, lights, air lines, and coupling still matter because a tank amplifies weight and stopping problems.
Use a repeatable sequence
Work outside, under, around, and on top only where safe access exists. Check before loading and again after loading, because a tank that was tight empty can leak when filled. For flammable cargo, verify grounding and bonding points and keep ignition sources away during loading or unloading. Never enter a cargo tank; confined-space entry requires separate training and equipment.
Worked example
A driver finds a drip under the discharge valve after loading gasoline. The weak answer is to tighten the packing and drive to the terminal. The reasoning: the drip is a product release on a flammable cargo. Set parking brake, shut down, stop loading, contain the drip if safe, close the valve, and notify the supervisor. Do not move a leaking tanker until the leak is controlled and qualified persons approve.
Traps that cost marks
Checking only the tractor; assuming a placard can be corrected later; ignoring an odor or wet streak; leaving a dome cover loose; and treating a drip as a minor cosmetic issue. The exam rewards finding and correcting the defect before movement.
