Answer

Proceed in the direction of the arrow if the way is clear
According to the Highway Code, when a green filter arrow is illuminated alongside a red light, you may proceed in the direction indicated by the arrow if your lane and the junction are clear.

Step-by-Step Solution

1
Identify the active signals on the traffic light assembly
Observe that the main signal shows red, but the dedicated left-turn green filter arrow is illuminated.
Traffic light junctions frequently control individual lane movements with dedicated filter arrows.
2
Apply the UK Highway Code rule for green filter arrows
Establish that turning left is permitted without waiting for the main circular green light.
A green filter arrow gives legal permission to move in the indicated direction provided the way is clear and safe.

Key Concept

An illuminated green filter arrow allows traffic to proceed in the indicated direction regardless of other lights showing.
