What is MOT vs Service?

An MOT and a service are different things often confused by drivers. An MOT is a legally required annual roadworthiness and emissions test for vehicles over three years old, focused on safety and pass/fail. A service is voluntary preventative maintenance — oil and filter changes, brake and fluid checks — carried out to the manufacturer's schedule to keep the vehicle reliable and protect its warranty. Passing an MOT does not mean a car is fully serviced, and a service is not a substitute for an MOT.
