Preparing your vehicle for an emissions test

What to prepare for your visit

Have the vehicle registration certificate ready to identify the vehicle. If you are also undertaking a mandatory roadworthiness inspection and use gas equipment, prepare its periodic test and safety-conformity documents. Keep previous measurements if returning after repairs. Confirm the final document list for your selected procedures when arranging the visit.

Pay attention to faults

The operator’s testing requirements refer to the exhaust system and vehicle fault indicators. If there is damage, leakage or an illuminated Check Engine warning, arrange diagnosis first.

A vehicle’s condition should be improved by fixing faults, not disabling warning indicators.

Test duration and repeat examinations

Agree the appointment time, test duration and repeat-examination charge with the station before visiting. Following a failed result, repair the identified faults and present the vehicle for repeat measurement. Charging rules for repeat roadworthiness inspections should not automatically be applied to an emissions examination.

How results are recorded

An electronic examination report is created after the test. The information is entered in an electronic register and retained in the specialised system for at least three years (paragraph 75). Check the vehicle details, date, measured values and conclusion. The station will explain how to obtain a copy or extract of the report.
