No Left Turn

What to Do

Continue by another legal movement that matches your lane and the traffic controls.

A Detail to Remember

A red slash cancels the left-turn arrow. Do not confuse it with a mandatory left-turn arrow inside a green circle.

Understanding Prohibitory & Parking Signs

The symbol tells you which activity is restricted. A time plate, arrow or additional message can limit when or where the restriction applies, so read the complete assembly rather than only the red marking.
