Regulatory signs

Vehicular traffic must proceed to the left

Vehicular traffic must proceed to the left sign

What it means

Turn left, and from this point that is the only way you are allowed to go - no straight on, no right. It is fixed at the junction itself, often at the entry to a one-way street. Get left early, signal in good time, and check your mirrors and blind spot for cyclists before you turn.

Highway Code Rule 109 — read it on GOV.UK
