California Car / Permit practice question · Road Signs

You approach a white circular sign showing a bicycle crossed out in red. What does it tell you to do?

Answer choices

• Bicycles are not allowed on this road.— Correct answer
• You may not make a U-turn at this location.
• You are traveling against traffic — turn around; you entered the wrong way.
• You must not drive slower than this speed under normal conditions.

Why this is the answer

A red circle with a line through it shows a picture of what you cannot do. When that picture is a bicycle, bicycles are not allowed on that road. It is not a U-turn ban, a wrong-way warning, or a minimum speed rule, since each of those uses a different symbol or wording. Follow the sign's instruction.
