What sign on the truck indicates the man should not ride?

• A. The sign on the truck says no riders
• B. The truck has a sign that says no passengers
• C. The driver wears a badge warning against riding
• D. The truck is marked with a no hitchhiking sticker

Answer: (A)

Interpreting signs that ban actions is about noticing language that clearly tells you what you can’t do. The best sign is the one that plainly states “no riders” because that wording directly communicates that no person may ride the truck, covering anyone who might hitch a ride or ride as a passenger. It’s unambiguous and universally understood as a prohibition of riding.

Other options either use less direct phrasing or refer to different ideas. A sign saying “no passengers” also forbids riding but is a bit narrower in common usage and can feel less immediate as a universal ban. A badge worn by the driver isn’t a sign on the truck itself, so it wouldn’t be the clear indicator you’re looking for. A sticker about no hitchhiking specifies a particular situation (hitchhiking) rather than the broader act of riding in or on the truck. So the most direct and comprehensive warning shown on the truck is the one that says no riders.
