DOT Inspections — Port Arthur, TX
Every commercial vehicle needs an annual federal periodic inspection. We run them at the Port Arthur shop, and two certified DOT inspectors work here: Luke Dugas and Mark Dugas Jr., the owner. Not a technician who has seen a few — named inspectors you can ask for by name.
Shop only, and here is why
We do not do mobile DOT inspections. An annual inspection means getting under the truck properly, checking brake stroke and lining thickness, and working through the whole vehicle in order. That is a bay-and-lift job, so it happens here.
What gets checked
The federal periodic inspection covers brake system and pushrod travel, coupling devices, exhaust, fuel system, lighting, steering, suspension, frame, tires, wheels and rims, windshield glazing and wipers, and emergency equipment. On a trailer that means landing gear, king pin, air lines, lights, and the same brake and running-gear checks.
What fails most often
In our bays it is rarely something dramatic. It is brakes out of adjustment or lining under limit, lights and wiring — a corroded ground or a chafed harness — tires under tread depth or with sidewall damage, air leaks at fittings and chambers, missing or expired emergency equipment, and cracked or broken mirrors and glass. Almost all of that is cheap to fix and free to check before you show up.
Why the shop wants your truck in the yard
We will say the quiet part out loud: an inspection puts your truck on our property with a technician under it. Some of those inspections turn up work, and some of that work we quote. What we will not do is invent it. Luke tells you what failed, what is legal but marginal and worth watching, and what is fine. If nothing needs doing, that is what you will hear.
Pre-inspection checklist — run this before you come in
- Walk every lamp with the flashers on: clearance, marker, tail, brake, turn, and license plate.
- Check tread depth — 4/32 on steers, 2/32 on drives and trailer — and look for sidewall cuts, bulges, and exposed cord.
- Air up, shut down, and listen. Chase any leak you can hear at chambers, glad hands, and fittings.
- Check brake adjustment and pushrod travel; look at lining thickness through the inspection slot.
- Confirm the fire extinguisher is charged and mounted, and the warning triangles and spare fuses are aboard.
- Look at the windshield for cracks in the wiper path, and check that both wipers actually clear.
- Check mirrors for cracks and loose mounts.
- Look under for leaks, hanging exhaust, loose air lines, and anything rubbing.
- Check the fifth wheel, landing gear, and king pin for cracks, play, and missing hardware.
- Make sure the last inspection report and your paperwork are actually in the truck.
