Two-Way Traffic sign

Warns of a change from a one-way or divided roadway to a two-lane, two-way road.

What to do

Stay to the right; traffic will be coming toward you.

Keep right and pass only where it is legal and you can see far enough, because oncoming vehicles now share the road with you.

Where it's used

Section 2C.51 says a Two-Way Traffic (W6-3) sign should be used to warn of a change from a multi-lane divided road to a two-lane, two-way road, and with an AHEAD (W16-9P) plaque where a one-way street becomes two-way. It is a black-on-yellow diamond with two vertical arrows pointing in opposite directions. It may also be repeated at intervals along a two-lane road or used to supplement the Divided Highway Ends sign.

Don't confuse it with

  • Divided Highway Ends: Divided Highway Ends shows the median ending, while Two-Way Traffic shows arrows going both ways.
  • Double Arrow: The Double Arrow sign points to both sides of an obstruction, not to traffic in two directions.
  • One Way (horizontal): The ONE WAY sign is a white regulatory sign meaning all traffic goes in one direction, the opposite situation.
