The two-way traffic straight ahead sign warns drivers that a previously one- way road will transition to two-way traffic ahead, so be prepared for oncoming vehicles and adjust position accordingly. Key points
- Purpose: Alert that the road you’re on or approaching will allow traffic in both directions, potentially reducing overtaking opportunities and increasing the likelihood of encountering opposing traffic.
- Visual: Typically a diamond/rectangular warning sign with a symbol indicating two-way traffic or lines converging to show opposing flow ahead.
- Action for drivers: Slow down if needed, scan for oncoming vehicles, be prepared for narrowing lanes or changes in road layout, and avoid risky overtaking until you’re clearly past the two-way section.
- Common contexts: Approaching a road that switches from one-way to two-way, or a dual carriageway reducing to a single lane with opposing traffic.
If you’d like, I can tailor guidance to the country you’re driving in (signs vary slightly by region) and provide examples of the exact sign design and placement.
