What Does a DOT Inspection Cover?
The primary purpose of a DOT inspection is to ensure your safety equipment is all functioning properly. Safety equipment includes but isn’t limited to your seatbelts, airbags, navigation lights, steering system, and brake systems. Anything that ensures you and others on the road are safe is included within this part of the inspection.
Emissions Control Systems
Another major part of your DOT inspection is your emissions control systems. In order to pass, all of your emissions control components must be functioning properly. These components include your EGR system, your DPF, your SCR catalyst, and your DOC.
Common problems that may cause your heavy-duty truck to fail the inspection include a stuck EGR valve, a clogged DPF, an SCR catalyst with a malfunctioning DEF injector, and other similar problems.
