What fails a DOT inspection most often

What fails a DOT inspection most often? Year after year, the same systems top the list, and they are systems you can stay ahead of. Here are the big ones.

Brakes

Brakes are consistently the largest single category, especially out-of-adjustment brakes and worn linings. They are also a top out-of-service item. Keeping the brakes right is the highest-value thing you can do before an inspection.

Lights and wiring

Lighting and electrical problems are right behind brakes, and they are the cheapest to prevent. Most repeat failures trace to a bad ground or a corroded connector, which is what our lighting and electrical work fixes for good.

Tires

Worn tread, exposed cord, and flats put you in a violation category inspectors check every time. A quick look at your tires catches it early.

Why it matters

All three are wear items. A truck on a maintenance schedule rarely fails on them, because the wear gets caught before the inspector ever sees it.

Bring it in for a DOT inspection and we will check all of it, then fix anything that needs it in the same stop.
