How to read signs like this
Regulatory signs tell you what the law requires: stop, yield, speed limits, turns and lanes. Most are white rectangles with black or red. Red means stop, yield or a prohibition; a red circle with a slash means “no”.
Practice question
This sign is posted at an intersection. What does it mean?
- A Left turns are allowed only on a green arrow
- B Left turns are not allowed from this approach
- C U-turns are banned, but left turns are allowed
- D Traffic in the left lane must turn left
Show answer
B. Left turns are not allowed from this approach
The red circle and slash mean prohibited, and the arrow shows which movement is banned. These signs are placed where drivers about to turn left will see them, such as over the road or on the far left corner. Plan ahead and use another route if you need to go left.
