Dry Van Trailer Inspection: A Printable Pre-Trip Checklist

A dry van trailer inspection takes ten minutes and saves days. An out-of-service order at a scale, a rejected trailer at a food shipper, or a wet-freight claim from a leaky roof all start with something a walk-around would have caught. The checklist at the top of this page is built to print and keep in the truck. It follows the trailer in the order you'd walk it, and lists the federal rule behind each item where there is one.

What the federal rules require

Three rules in Part 392 and Part 396 of the Federal Motor Carrier Safety Regulations shape a pre-trip:

• Before driving: you can't drive unless you're satisfied that the service brakes and trailer brake connections, parking brake, lights and reflectors, tires, coupling devices, wheels and rims and other listed parts are in good working order (49 CFR 392.7). You also have to be satisfied the vehicle is in safe operating condition and review the last inspection report where one was required (49 CFR 396.13).
• After the day's driving: a written report is required for defects found or reported on the parts listed in 49 CFR 396.11. If nothing is found, no report is required, and carriers with a single commercial motor vehicle are excepted from that section.
• Every 12 months: the trailer needs a periodic inspection, with proof kept on or in the vehicle (49 CFR 396.17).

The parts themselves have their own rules, like tire condition in 49 CFR 393.75 and lighting and conspicuity tape in 49 CFR 393.11.

Walk the trailer in five zones

1. Coupling and front

Pull against the trailer with the brakes set to test the fifth wheel lock, then look: the jaws should be closed around the kingpin with no gap between the fifth wheel plate and the trailer's upper plate. Air lines and the electrical cord should be connected, supported and not rubbing. Raise the landing gear fully and stow the handle.

2. Sides and lights

Turn on every light and walk around. Marker and clearance lamps, turn signals, brake lamps and reflectors all count. Conspicuity tape needs to be present and visible; grimy tape is easy to miss and easy to clean. Look for fresh damage on the side walls, especially around the logistics posts.

3. Tandems, tires and brakes

This is where most out-of-service problems live. Check every tire for tread depth, cuts, bulges and leaks. Look at the wheels for cracks and rust streaks from loose lug nuts. Check hub seals for oil. Look at brake chambers, hoses and slack adjusters. If you've moved the tandems, make sure every slider pin is engaged before you pull out.

4. Rear, doors and inside the box

The rear impact guard needs to be in place and straight (49 CFR 393.86). Doors should open and close square, with hinges, lock rods and cams working and gaskets intact. Then climb in: check the floor for holes, soft spots and nails, and close the doors to look for daylight through the roof and walls. A pinhole of light is a wet-freight claim waiting to happen. If the load needs securing, make sure load bars or straps are on board.

5. Paperwork

Annual inspection current, registration on board, last inspection report reviewed and signed if it listed defects, and the seal number on the door matching the bill of lading.

Extra checks for food and high-value loads

Some shippers inspect your trailer before they'll load it. For dry food loads, expect them to look for a clean, dry, odor-free floor and no signs of pests; our guide to food grade dry van requirements covers what the FDA rule asks of carriers. For high-value freight, the seal and door hardware matter as much as the floor; see trailer seals and cargo security.

Trailer type changes the inspection

A plate (thin-wall) van, a sheet-and-post van and a vented van each have their weak spots: plate walls hide damage from impacts, older sheet-and-post walls loosen at the rivets, and vents need to close and seal. Our guide to types of dry van trailers explains the construction behind each.

What inspections cost you when you skip them

A trailer that's put out of service, or rejected at the dock, loses the load and the day. Repairs on the road cost more than repairs at your shop. Build maintenance into your numbers with the dry van cost per mile calculator, so the money for tires and brakes is there before you need it.

Inspection weeks like CVSA's International Roadcheck come every year; our dry van freight calendar has the dates.

We review the rule references each year and when FMCSA changes the rules. The checklist is a walk-around aid, not a replacement for the regulations or your own maintenance program.

Where dispatch comes in

A dispatcher can't inspect your trailer, but we do plan around it: we don't book a load that leaves no time for a pre-trip, and we keep your annual inspection date and broker paperwork on file. See the kinds of dry van loads we book, learn more about our dry van dispatch service, or read more dry van guides.

Trailer inspection questions

What do I check on a dry van trailer before a trip?

The coupling (fifth wheel locked, air and electrical lines connected), lights and reflectors, tires, wheels and rims, brakes, the rear impact guard, doors and seals, the floor and roof from inside, and the annual inspection paperwork. The checklist on this page lists each item with the rule behind it.

Do I need a written inspection report every day?

Under 49 CFR 396.11, a driver vehicle inspection report is required after each day's work for the parts listed in the rule, but drivers don't have to prepare one if no defect is found or reported. Carriers operating only one commercial motor vehicle are excepted from that section. Check the rule for your operation.

How often does a trailer need an annual inspection?

Every commercial motor vehicle, trailers included, must pass a periodic inspection at least once every 12 months, and proof of it has to be kept on or in the vehicle (49 CFR 396.17). It's usually a decal on the trailer plus the report in your files.

What is the minimum tread depth for trailer tires?

2/32 of an inch in a major tread groove for tires other than a tractor's front tires, which need 4/32 (49 CFR 393.75). Tires also can't be flat, have an audible leak, show exposed ply or belt material, or have tread or sidewall separation.

Who's responsible if I hook a trailer someone else owns?

You are, for driving it. The driver must be satisfied the equipment is in safe operating condition before driving (49 CFR 392.7 and 396.13), whether it's your trailer, a shipper's or a broker's. Write up defects before you leave the yard.
