Rule 273: Leaving by the slip road
Advice, not law
Leaving the motorway (rules 273 to 274)
Unless signs indicate that a lane leads directly off the motorway, you will normally leave the motorway by a slip road on your left. You should
- watch for the signs letting you know you are getting near your exit
- move into the left-hand lane well before reaching your exit
- signal left in good time and reduce your speed on the slip road as necessary.
Advice, not law. This rule is not written in capitals, so breaking it is not an offence in itself — but it can still be used in evidence in court to establish liability. The rules that say MUST or MUST NOT are the ones backed by law.
