Rule 89: Vehicle condition
Legal requirement — says MUST
Vehicle condition (rule 89)
Vehicle condition. You MUST ensure your vehicle and trailer comply with the full requirements of the Road Vehicles (Construction and Use) Regulations and Road Vehicles Lighting Regulations (see ‘The road user and the law’).
Why the capitals matter. The Highway Code writes a rule in capitals — MUST or MUST NOT — when it is backed by law, so breaking it is a criminal offence. The rules that do not use capitals are advice.
