Zorluk: OrtaLane Discipline and Positioning

When traffic is congested and moving at very low speeds towards an upcoming lane closure, drivers should use all available lanes and merge in turn just before the obstruction point.

Cevap: Cevap

Cevap

True. In slow-moving, congested conditions, using both lanes and merging in turn ('zip-merging') just before the lane closure is the correct procedure to maximise road capacity and prevent long single-lane tailbacks.
The statement is true because Highway Code Rule 134 specifically instructs drivers to use both lanes and merge in turn when traffic is travelling at very low speeds in congested conditions. This zip-merging technique balances traffic volume across the carriageway and prevents unnecessarily long tailbacks.

Adım Adım Çözüm

1
Assess the prevailing traffic speed and congestion level approaching the roadworks.
The traffic is identified as heavily congested and moving at very low speeds.
The Highway Code establishes different lane discipline guidelines for free-flowing traffic versus slow-moving, queuing traffic.
2
Apply Highway Code Rule 134 regarding lane discipline and merging near closures.
Drivers are advised to use both lanes and merge in turn (zip-merge) just before the taper of the closure.
Merging in turn at low speeds optimises available carriageway space, ensures fair progression, and prevents queues from backing up across upstream junctions and roundabouts.

Anahtar Kavram

Lane discipline and zip-merging in slow-moving traffic before lane closures (Highway Code Rule 134).
