Warning sign

Road narrows on both sides

This warning triangle tells you the road ahead narrows. It may narrow on both sides or just one; a separate plate or sign shows which side gives way where the road narrows.

When you see it

  • Be prepared for the carriageway to become narrower ahead.
  • Watch for oncoming vehicles and be ready to give way if needed.
  • Do not speed up to get through a narrowing before another vehicle.
  • Take extra care with the width of larger vehicles such as lorries and buses.
