Which statement about crossing a single broken line is true?

• A. You may cross if you are not interfering with traffic
• B. You may cross only when you are not interfering with traffic
• C. You may cross at any time
• D. You may never cross

Answer: (A)

A single broken line means you may cross it to pass or change lanes when it’s safe and you won’t interfere with other traffic. That’s why the statement “you may cross if you are not interfering with traffic” is the best answer—it focuses on crossing only when it won’t disrupt others. Crossing isn’t allowed if it’s unsafe or would impede oncoming vehicles, and it isn’t correct to say you may cross at any time or never cross.
