Understanding the Importance of DOT Inspections

Every commercial motor vehicle (CMV) that operates on public roads must undergo regular DOT inspections. These inspections aim to identify parts and accessories in your diesel truck, trailer, or fleet that might not be in optimum condition, ensuring the vehicle's safety and operational capacity.

Federal-Level vs. State-Level DOT Inspections

While there are overarching federal DOT guidelines, it's vital to remember that each state can also introduce additional rules and regulations. Here’s what to keep in mind:

Federal-Level Inspections: Mandated by the Federal Motor Carrier Safety Administration (FMCSA), these inspections focus on the vehicle's general health. They might include checking the brake systems, coupling devices, exhaust systems, frames, fuel systems, lighting devices, steering mechanisms, suspensions, and tires.

State-Level Inspections: Depending on the state, additional checkpoints or specific criteria may differ from the federal guidelines. For businesses operating in or passing through Arizona, it's crucial to ensure your vehicles align with Arizona’s specific state regulations.
