Rhode Island Emissions

Rhode Island requires emissions testing if you are looking to receive an original registration or if you are planning to renew your annual registration. Notifications are sent out annually to the owners of vehicles so that they will understand when they should have a test completed and whether it is required.

If your vehicle is less than 8500 pounds and is a car, truck, motorhome or RV you will be required to have an emissions test in the state of Rhode Island. You also need to have one completed if you are participating in a private sale or a transfer ownership for an out-of-state purchase. If this is the case, you will need to have your vehicle inspected within five days.

If you own a semi-trailer that weighs over 1000 pounds, a livestock trailer motorcycle, these must all be inspected by 30 June every year.


An emissions testing is valid for two years and you will need one if you are reinstating a suspended registration or completing a registration renewal or original registrations. Vehicles that are over 8500 pounds, trailers and motorcycles are to be inspected annually.

There are some exemptions when it comes to emissions testing and if you own an electric vehicle you will not be required to have and emissions testing. You will also not need one if your vehicle is newer than two years or has less than 24,000 miles or it has been registered with an antique tag. These are vehicles that are over 25 years old.

Locations and Fees

Inspection stations must be licensed by the state in order to be allowed to inspect your vehicle. There are a maximum and standard set on the fees and this must be displayed within the station. There are only a handful of stations that deal with light-duty diesel vehicles.

This fee of the testing varies depending on the County, type of vehicle and fuel that it used and typically falls between $11 and $39. However, the maximum fees will be listed in the station and you can call ahead to see what the fees will be before you take your vehicle in.


If your vehicle does fell the emissions test you will be required to have it repaired and retested within 30 days. It is up to you where you have the vehicle repaired but many of the inspection stations offer discounts, such as “no pass no pay”, where if your vehicle does not pass the testing, you will not have to pay for the repair.

There are also some waivers that you may be able to qualify for if your vehicle has been repaired to the maximum that it can be repaired to, if you had spent more than $700 or if you fall into the low income group. In order to learn more about this you should talk to the DMV to learn if you qualify.


Your inspection station will be able to provide you with more information regarding what is required and how the inspections take place. If you do find that you fail the tests they will also be able to provide you with the information needed to know how to fix your vehicle so that it will pass with the next inspection.
