CVRT Tester cheat sheet

CVRT is the annual roadworthiness test for commercial vehicles in Ireland, administered by the RSA and conducted at authorised test centres.

Test categories include light commercial vehicles (up to 3,500 kg), heavy commercial vehicles (over 3,500 kg), buses, and trailers; each has specific inspection criteria.

A CVRT pass certificate is issued when the vehicle meets all required standards; a fail results in a detailed report listing defects, and a re-test is required after repairs.

The test includes checks on braking performance, steering, suspension, lights, tyres, bodywork, emissions, and safety equipment, with emphasis on load security for goods vehicles.

Vehicles must be presented with valid identification (registration certificate) and the appropriate fee; late testing can lead to fines and penalty points.

CVRT test results are recorded in the National Vehicle and Driver File (NVDF), and a pass certificate must be displayed or available for inspection.

Annual testing is mandatory for vehicles over one year old for light commercial vehicles, and over one year for heavy commercial vehicles, with some exemptions for vintage vehicles.

The CVRT tester must be trained and authorised by the RSA; testers follow detailed manuals and use calibrated equipment to ensure consistency.

Braking standards: service brake must achieve at least 50% efficiency, secondary brake at least 25%, and parking brake at least 16% for vehicles first registered after 1 January 2010.

Steering system: no excessive play, components securely mounted, power steering functional, and no leaks; steering wheel must not have excessive free play.

Suspension: springs, shock absorbers, and linkages must be in good condition, with no excessive wear, corrosion, or leakage.

Lighting: all mandatory lamps must be present, clean, and functional; headlamps must be correctly aimed, and reflectors must be intact.

Tyres: minimum tread depth of 1.6 mm for cars and light commercial vehicles, 1.0 mm for heavy vehicles; no cuts, bulges, or exposed cords; correct tyre size and type.

Emissions: diesel vehicles must not exceed smoke opacity limits; petrol vehicles must meet CO and HC limits; test using approved analysers.

Bodywork and chassis: no excessive corrosion affecting structural integrity; doors, latches, and hinges must operate correctly; windscreen must be free of damage in the driver's view.

Load security: for goods vehicles, check that the load is secured and does not affect stability; covers and restraints must be in good condition.
