If you operate a diesel truck in California, especially a 2013 or older heavy-duty diesel truck, the Truck Smog OVI Test (CARB Test for Diesel Trucks) in Fontana is now a mandatory part of your compliance checklist. The state of California, through its Clean Truck Check Program, has enforced strict smog testing rules for diesel vehicles to help reduce air pollution and ensure environmental safety.

This blog will help you understand the OVI inspection for trucks in Fontana, why it matters, and how Clean Truck Check LLC can help you stay compliant without the stress.

What is the Truck Smog OVI Test (CARB Test for Diesel Trucks) and Why is It Mandatory in Fontana?

The Truck Smog OVI Test (CARB Test for Diesel Trucks), also known as the Opacity Vehicle Inspection (OVI), is a part of California’s Clean Truck Check program administered by the California Air Resources Board (CARB). This test is designed to monitor and limit the amount of harmful emissions released by heavy-duty diesel trucks, particularly those that are model year 2013 or older.

Explanation of OVI (Opacity Vehicle Inspection)

The OVI test (CARB Test for Diesel Trucks) measures the amount of black smoke (opacity) emitted from the exhaust of your truck. High opacity levels indicate excessive emissions and potential engine issues. CARB requires that these trucks undergo regular inspections to ensure they meet the state’s air quality standards.

CARB Regulations Overview

CARB has identified diesel trucks as one of the major contributors to harmful air pollutants such as nitrogen oxides (NOx) and particulate matter (PM). To mitigate this, CARB implemented the Clean Truck Check program. If you own a diesel truck over 14,000 lbs. and it’s model year 2013 or older, you’re required to get an OVI inspection (CARB Test for Diesel Trucks) in Fontana or any other approved location in California.

Role of the Test in Reducing Diesel Truck Emissions

The purpose of the Truck Smog OVI Test (CARB Test for Diesel Trucks) in Fontana is not just regulatory—it’s environmental. These inspections help:

  • Detect malfunctioning emission control systems

  • Prevent excessive pollutants from entering the air

  • Promote engine efficiency and longer lifespan for your trucks

Applicable Vehicles: 2013 and Older Heavy-Duty Diesel Trucks

If your diesel truck is from model year 2013 or earlier, it falls under the current OVI testing mandate. Trucks newer than 2013 may still be subject to future testing schedules, but for now, this specific rule is focused on older vehicles known for higher emission rates.
