Many regulatory signs tell you what you may not do: turn, enter, pass, or use a lane for the wrong purpose. Work zone signs are orange and protect people working on the road, and the fines there are doubled.

Know the rule

A red circle with a red slash over a symbol means that action, such as a left turn, right turn, or U-turn, is not allowed.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

How does a construction-zone fine compare to normal when workers are present?
  1. It's reduced by half
  2. It's capped regardless of speed
  3. It's doubled
  4. It's the same

Answer: It's doubled

Fines double for offenses committed while driving in construction areas when workers are present.

What does a regulatory sign with a red circle and a red slash over a symbol mean?
  1. A recommendation, not a rule
  2. That action isn't allowed
  3. That action is required
  4. A warning about upcoming hazards

A red circle with a red slash over a symbol shows that action, like a U-turn, isn't allowed.

What does a Do Not Enter sign look like?
  1. A square sign with a white horizontal line inside a circle
