211. Defects
Defects are faults, damage or wear that can affect a vehicle’s safety, roadworthiness or compliance with technical requirements. Defects may involve tyres, brakes, lights, steering, suspension, windows, bodywork, electrical systems or other components. Some are minor and should be repaired as soon as possible, while serious or dangerous defects can make the vehicle unsafe to drive. Drivers should regularly check their vehicle and repair problems before they become a safety risk.
