You must check your mirrors, adjust your road position, and prepare for oncoming vehicles. Reduce your speed if necessary to ensure safe navigation.

The sign does not indicate road width. It only warns that vehicles will approach from the opposite direction. A Narrow Road Sign provides a separate warning about road width.

Yes. The sign is placed where a dual carriageway ends, meaning there is no longer a central reservation separating traffic directions.

Actions to Take When You See a Two Way Traffic Sign

When you see a Two Way Traffic Sign, you must prepare for oncoming vehicles and adjust your driving accordingly. Check your mirrors to assess surrounding traffic before entering the two-way section.

Slowing down is necessary if road conditions, traffic volume, or visibility require it. Adjust speed based on the road ahead and presence of oncoming vehicles.
