Do I Need An Inspection For My Diesel Truck?

Besides diesel maintenance, we also offer diesel inspections, a necessary service for all auto owners in New York. In order to legally drive your vehicle in New York, you must take it to a NYS diesel truck inspection certified mechanic. TLC auto & Truck Repair Service Center is certified to perform diesel truck inspections to ensure your vehicle is functioning properly.

Besides legal and safety reasons, you may also need a diesel inspection because:

Whatever your need be, we’re here to ensure the highest quality and standard of service to keep you and others safe on the road. Keep in mind that these inspections are required annually if your vehicle is registered within DEMA (Diesel Emissions Metropolitan Area).

What Our Diesel Inspections Include

Customer satisfaction is top priority at TLC, which is why we offer additional perks with every diesel inspection. 

Most diesel-powered vehicles that have a Gross Vehicle Weight Rating (GVWR) greater than 8,500 pounds and are registered in the New York Metropolitan Area, are required to take a smoke opacity test. This includes all vehicles registered in one of the five counties in NYC, Nassau, Suffolk, and Rockland counties. If this is you or you have any questions on whether or not you’re in need of a diesel emissions inspection, call us at (631) 753-2211. We’re happy to answer any and all questions, and/or schedule an appointment for your diesel truck inspection.

We offer free pickup and dropoff services for you. We understand that you may not have the means to wait around for us to complete your diesel truck inspection. Maybe you only have one car, you need to run errands, or you have to pick up your kids. Whatever the case, we understand that sometimes you need that extra time/help in the form of pickup and dropoff services. We’ve got you covered.
