Do Not Enter sign

What does it mean?

DO NOT ENTER prohibits entry into the road or ramp from the direction facing the sign. It commonly protects one-way traffic from a driver approaching the wrong entrance.

What to do when you see it

  1. Keep out of the signed entrance.
  2. Check directional signs before selecting a different route.
  3. Do not treat an empty ramp as permission to enter.

How to recognize it

  • Red circle on a white square.
  • Wide horizontal white bar across the circle.
  • White DO NOT ENTER wording.

On the road

Your navigation suggests a ramp, but a DO NOT ENTER sign faces you at its mouth. Stay out of that ramp and continue to a legal entrance.

Don’t confuse it with

Wrong Way sign

DO NOT ENTER is an entry prohibition; WRONG WAY warns that your direction conflicts with the permitted flow.

No Outlet sign

NO OUTLET describes a road network without a through exit; it does not prohibit entry.
