Annual DOT inspections in California are run for commercial vehicles, such as commercial trucks. They are carried out by our qualified inspectors to identify potential issues and ensure vehicles are operating safely on public roads.

What Does a DOT Annual Inspection Involve?

A DOT inspection goes beyond the basic inspection of your vehicle. 

Brake System

Inspectors thoroughly examine the braking system to ensure it functions properly and efficiently, as brakes are critical for safe vehicle operation.

Tires and Wheels

The condition of tires and wheels is assessed to identify any signs of wear, damage, or improper inflation, which could lead to accidents.

Lights and Signals

All lights and signals are inspected to ensure proper functionality for signaling intentions and maintaining visibility.

Steering and Suspension

The steering and suspension systems are inspected for any issues that might affect the vehicle’s stability and control.

Fuel System

The fuel system is examined for leaks or other potential hazards, as fuel leaks can be dangerous and lead to fires.

Exhaust System

Inspectors verify that the exhaust system is in good condition, as leaks could result in harmful emissions and compromise air quality.

Coupling Devices

Coupling devices, such as fifth wheels, are assessed to ensure they are secure and can properly connect the vehicle to its trailer.

Frequency of DOT Controls 

Based on their frequency, DOT inspections are classified into 3 categories:

Level I Inspections

These are comprehensive checks covering all aspects and parts of the vehicle.

Level II to VI Inspections

They focus on specific components of the vehicle and may be conducted at random checkpoints or as part of targeted enforcement campaigns.

Special Inspections

These are conducted when a vehicle is suspected to have safety issues or has been involved in an accident.

Why are DOT Inspections Important?

Ensure Vehicle Safety

Annual controls help identify potential mechanical issues. 

Prevent Non-Compliant Vehicles

Inspections ensure that every commercial truck and all commercial vehicles comply with the regulations set by the Department of Transportation. Non-compliant vehicles can pose serious risks to the driver, other road users, and the environment.

Reduce Road Accidents

Regular checks can prevent accidents caused by vehicle malfunctions, such as brake failures or tire blowouts. 

Protect the Environment

Properly maintained vehicles emit fewer harmful pollutants, which contributes to better air quality and environmental protection.

Promote Industry Accountability

Along with DOT inspections, BIT inspections hold terminal facilities accountable for maintaining safe and compliant working environments. A BIT inspection of terminals promotes responsible practices within the commercial transportation industry.

Avoid Costly Penalties

Non-compliance with road check regulations can lead to hefty fines and penalties for drivers and companies by the California Highway Patrol. Regular inspections help avoid these financial burdens.

A DOT inspection for commercial vehicles is mandated to ensure road safety and compliance with state and federal regulations, promoting the safe operation of these vehicles on public roads.

You can get a DOT inspection done at certified inspection stations, including authorized garages, service centers, and our company’s facilities throughout California.

A DOT inspection typically involves a thorough check of the vehicle’s essential systems, including brakes, steering, tires, lights, and engine components. Additionally, inspectors will request to review the driver’s logbook for hours-of-service compliance, verify driver qualifications, and if applicable, inspect procedures and equipment for hauling hazardous materials.

The frequency of DOT inspections varies depending on the type of inspection. For example, an annual check is required for all commercial vehicles.

If your vehicle fails the DOT inspection, it needs to undergo necessary repairs and be re-inspected to meet safety and compliance standards before it can legally operate on public roads.

A typical DOT inspection usually takes around 30 minutes to an hour, depending on the vehicle’s size and condition.

You’ll typically need vehicle registration, proof of insurance, and maintenance records demonstrating regular servicing and repairs.

No, a DOT inspection specifically focuses on safety and compliance standards for commercial vehicles, while a regular vehicle inspection covers general safety aspects for personal vehicles.

The main difference between a DOT (Department of Transportation) inspection and a BIT (Bureau of Inspections and Training) inspection in California lies in their focus: DOT inspections are federally mandated for commercial vehicles nationwide, while BIT inspections are specifically required for certain commercial vehicles in California to ensure compliance with state regulations. Both inspections assess vehicle safety but have distinct regulatory scopes and standards.

Short Notice, they took my trailer the same day and said they would be able to look at it in a week. Joseue called me a couple days later and told me he did. He made sure everything worked to its potential and called me to get the trailer. It was a day before they said they would be able to look at it. It thought it was going to cost like $500 but it was only a couple hundred bucks. Great service and awesome value.

Got locked out of my car outside of Walmart. One of the guy that works for this company stopped to help us out and was able to unlock it less than 5 seconds. Didn’t get to ask for his name but shout out to him! Thanks again bro- Blue Mustang🚙

We travel full time for work and currently staying at an RV Park in Woodland. Our 5th wheel has had a couple of issues pop up and each time we’ve called they’ve been prompt on response, quick to come out, and professional. Their prices are also very reasonable. We will continue to recommend them!

I can’t recommend United Fleet Maintenance highly enough! These guys are wonderful, and I will be telling everyone I can about them! I was dead in the water so to speak, I just started living in my RV when my batteries stopped holding a charge. My fridge wasn’t working, no lights, etc. I called Camping World and they were trying to recommend people from the Bay Area. I knew I would rather have someone more local and when I called these guys and they said they worked on RVs I was so happy. Josue came out and figured out it was my controller and even suggested a work around for me until the part came in so I was actually able to get back up and running (with the work around) right away. Then he came back with the part and I am so very happy. This is what the service industry used to be, and with UFM it is again, people who are happy while they are there with you, have a smile on their face and really care about helping you. I think my problem was probably pretty small, I think Josue could fix almost anything and he loves what he does. I will use them again and recommend to everyone.

Reliable and honest mobile mechanic. Josue knows his stuff. From doing regular maintenance and DOT inspections to diagnostic repairs on my diesel trucks, dump trailers, wood chippers, stump grinders, and skid steers - Josue gets it done and backs all of his work. Nina breaks up my billing so I can track repair expenses for each piece of equipment. They are so easy to work with its unreal! Thank you Josue and Nina!

Professional and on time. In a world where trailer repairs are backed up for months, Josue fixed my heater when I needed it- conveniently at my house- so I could take my family camping. Payment thru Venmo and having the repair done while I was at work was so convenient for this working single mom. Thanks so much, you've earned my repeat business!
