What does 542.004 say about work on highway surface?

• A. This subtitle does not apply to a person, team, motor vehicle, or other equipment engaged in work on a highway unless the provision is specifically made applicable, but it does apply to those traveling to or from that work.
• B. The subtitle applies equally to all workers on highways at all times.
• C. The subtitle prohibits all highway work.
• D. The subtitle applies only to private roads used for work.

Answer: (A)

This section sets the scope of the subtitle: it doesn’t automatically apply to people or equipment actively working on a highway unless a specific provision makes it applicable. In other words, those performing highway work are governed by other rules unless the code says this subtitle should apply to them. However, the rules do apply to people traveling to or from the work site, so drivers and nearby road users still must follow the safety provisions around the work zone.

This explains why the other options aren’t right: it isn’t a blanket rule that applies to all workers all the time, it doesn’t prohibit highway work, and it isn’t limited only to private roads.
