CVRT definition

Commercial Vehicle Roadworthiness Test: mandatory annual inspection in Ireland for commercial vehicles to ensure they meet safety and environmental standards.

Test frequency for LCVs

Light commercial vehicles up to 3,500 kg must undergo CVRT annually once they are more than one year old from first registration.

Test frequency for HCVs

Heavy commercial vehicles over 3,500 kg must undergo CVRT annually once they are more than one year old from first registration.

CVRT pass certificate

Document issued after a vehicle passes all required inspections, valid for 12 months, and must be displayed or produced on demand.

CVRT fail report

Detailed list of defects found during test; vehicle must be repaired and re-tested within a specified period, often 30 days, to avoid full re-test fee.

RSA role in CVRT

Road Safety Authority oversees CVRT, sets standards, authorises test centres and testers, and maintains the National Vehicle and Driver File.

Test centre equipment

Authorised centres use calibrated roller brake testers, headlamp aimers, emission analysers, and pit lifts to perform standardised inspections.

NVDF record

National Vehicle and Driver File: central database storing vehicle registration, test results, and licensing details; test centres update it after each test.

CVRT tester authorisation

Testers must complete RSA-approved training, pass assessments, and undergo periodic audits to maintain authorisation to conduct CVRT inspections.

Re-test time limit

After a failed CVRT, the vehicle must be re-tested within 30 days to avoid a full test fee; only failed items are re-inspected.

Brake efficiency minimum

Service brake must achieve at least 50% efficiency, secondary brake 25%, and parking brake 16% for vehicles registered after 1 January 2010.

Tyre tread depth LCV

Minimum legal tread depth for light commercial vehicles is 1.6 mm across the central three-quarters of the tyre around the entire circumference.

Tyre tread depth HCV

Minimum legal tread depth for heavy commercial vehicles is 1.0 mm across the central three-quarters of the tyre around the entire circumference.

Headlamp aim check

Headlamps must be correctly aimed using approved equipment; incorrect aim can cause dazzle and is a test failure item.

Steering free play limit

Excessive free play in steering wheel is a defect; typically should not exceed 30 mm for vehicles with power steering, measured at rim.

Suspension inspection points

Check springs, shock absorbers, linkages for wear, corrosion, fractures, and leaks; any excessive deterioration is a fail.

Diesel smoke opacity

Diesel vehicles must not exceed smoke opacity limits measured by approved opacimeter; excessive smoke indicates poor combustion or engine wear.

Petrol emission limits

Petrol vehicles must meet CO and HC limits at idle and fast idle; typically CO ≤ 0.5% and HC ≤ 200 ppm at idle for vehicles with catalytic converters.

Windscreen damage criteria

Windscreen must be free of cracks, chips, or scratches in the driver's line of vision; minor damage outside this area may be acceptable.

Load security check

For goods vehicles, ensure load is secured and does not affect stability; check restraints, covers, and container locks for condition.

Bodywork corrosion

Excessive corrosion affecting structural components, such as chassis, outriggers, or suspension mounts, is a test failure.

Lighting requirements

All mandatory lamps (head, tail, brake, indicator, fog, reversing) must be present, clean, and functional; lenses must be correct colour and not obscured.

Seat belt condition

Seat belts must be securely mounted, free from cuts, fraying, and damage; retractor must function correctly; buckle must secure properly.

Exhaust system integrity

Exhaust must be secure, without leaks, and not excessively noisy; catalytic converter and particulate filter must be present if originally fitted.

Brake component inspection

Check brake pads, discs, drums, lines, and hoses for wear, corrosion, leaks, and correct operation; any unsafe condition is a fail.

Steering component check

Inspect steering box, linkages, joints, and power steering for play, wear, leaks, and security; any excessive play or leakage is a defect.

Warning lamp check

Dashboard warning lamps for brakes, ABS, airbags, and engine must illuminate when ignition is switched on and extinguish after starting.

Vehicle identification number

VIN must be present, legible, and match registration documents; missing or altered VIN is a test failure.

Fuel and oil leaks

Any excessive fuel or oil leaks are defects; minor seepage may be noted but significant leaks require repair before passing.

Mirror requirements

Vehicles must have adequate mirrors for rearward visibility; missing, cracked, or insecure mirrors are defects.

Speedometer functionality

Speedometer must be present and functional; it should not be excessively inaccurate, though slight variance is acceptable.

Horn operation

Horn must emit a continuous, uniform sound audible at a reasonable distance; malfunctioning horn is a test failure.
