Rule 139: Climbing and crawler lanes
Advice, not law
Multi-lane carriageways (rules 133 to 143)
Climbing and crawler lanes. These are provided on some hills. Use this lane if you are driving a slow-moving vehicle or if there are vehicles behind you wishing to overtake. Be aware of the signs and road markings which indicate the lane is about to end.
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.
