The term DOE test refers to an annual commercial vehicle test (CVT) required for goods vehicles in the Republic of Ireland. The DOE term refers to the Department of the Environment. The test was introduced in 1980. In 2005 Department of Transport took over jurisdiction over vehicle testing, and the test was then called DOT Test. In 2006 Road Safety Authority RSA was established, which took over the legislation regarding the test and monitoring of testers. RSA introduced VTN "Vehicle Testing Network" branding for Test Centres, and renamed the test to Commercial Vehicle Test (CVT), which is used presently.

There are a number of testers in every county of the Republic of Ireland. There are 2 main types of tests. The LGV test comprises a test on vehicles under 3500 kg gvw (gross vehicle weight) and the HGV test on all vehicles over this threshold. In general the LGV test applies to vans and the HGV test applies to trucks.

Test Operation[edit]

The DOE test examines all aspects of a vehicle's performance, in particular the suspension, brakes and emissions system. In recent years, the test has been altered to ensure that vehicle emissions correspond to a properly performing engine and exhaust system. The HGV test is a little more complex, as it also verifies tachograph operation and the presence of a road speed limiter.

The DOE test is required every year, and without a pass certificate the vehicle cannot be taxed or used on the road.
