- Follow the direction of travel indicated on the sign.
Follow the direction of travel indicated on the sign. Follow the single straight-ahead arrow; turning is not an alternative offered by this sign.
How to recognise the sign
A circular blue sign with white arrows or a white symbol identifying the road users concerned.
Supplementary panel and application
The arrow or arrows determine the permitted direction. Read any panel exemption and establish priority separately.
Difference from D5 — Compulsory direction
D4: Follow the direction of travel indicated on the sign. D5: Mandatory direction of travel: to the right. Read the separate application of D5 too; similar appearance does not mean identical meaning.
