CMG Vehicle Testing is a vehicle testing station on Riccarton Road in Christchurch, holding a 4.9 rating from 22 Google reviews, with customers describing quick, stress-free warrant of fitness and certificate of fitness inspections explained in plain language. A warrant of fitness covers the safety basics, such as tyres, brakes, lights, seatbelts, rust and steering, while a certificate of fitness is the more demanding inspection required for heavier vehicles like trucks, buses and motorhomes. A good tester is strict but fair: minor faults such as headlight aim can often be adjusted on the spot rather than recorded as a fail. Before any inspection it pays to check your lights, tyre tread and wipers yourself, as those are the most common easy fixes. Above all, look for a station where the tester takes the time to explain what was found and why. That mix of thoroughness and plain talking is exactly what reviewers say they found at this Riccarton Road station.
