About This Sign

This sign is placed at the end of a median or obstacle where traffic can pass on either side.

Where you will see it

You meet this sign at the front end of a median or other obstacle in the road, where traffic is allowed to pass on either side of it.

What to do

  • Slow down as you approach the obstacle.
  • Choose the side that fits where you are going and stay in your lane.
  • Watch for other vehicles passing on the opposite side.

A common mistake

Drivers sometimes think the arrows mean they must go one particular way. The two arrows mean either side is allowed, so the choice is yours, as long as it is safe.

What to remember for the test

Remember that the arrow pointing both ways means traffic may pass on either side of the obstacle. It is a warning sign, so expect a diamond shape and yellow colors.
