Rule 140
Cycle lanes and cycle tracks . Cycle lanes are shown by road markings and signs. You MUST NOT drive or park in a cycle lane marked by a solid white line during its times of operation. Do not drive or park in a cycle lane marked by a broken white line unless it is unavoidable. You MUST NOT park in any cycle lane whilst waiting restrictions apply. You should give way to any cyclists in a cycle lane, including when they are approaching from behind you – do not cut across them when you are turning or when you are changing lane (see Rule H3 ). Be prepared to stop and wait for a safe gap in the flow of cyclists before crossing the cycle lane. Cycle tracks are routes for cyclists that are physically protected or located away from motor traffic, other than where they cross side roads. Cycle tracks may be shared with pedestrians. You should give way to cyclists approaching or using the cycle track when you are turning into or out of a junction (see Rule H3 ). Be prepared to stop and wait for a safe gap in the flow of cyclists before crossing the cycle track, which may be used by cyclists travelling in both directions. Bear in mind that cyclists are not obliged to use cycle lanes or cycle tracks. Law RTRA sects 5 & 8
