This sign means?
- Permissive sign ✓
- Route for large trucks
- Roundabout ahead
- Do not enter
Answer: A. Permissive sign
It means this is a permissive sign, telling you the activity shown is allowed.
Why this is the answer
The handbook groups signs by the job they do and says regulatory signs give a direction you must obey. Within that group, a sign with a green circle means you may or must do the activity shown inside the ring. A permissive sign works the same way: rather than ordering you to stop doing something, it tells you the action pictured is permitted. So when a sign permits something, the answer is a permissive sign.
Why the other answers are wrong
- B. Route for large trucks — The passages never mention a sign marking a route for large trucks, so there is nothing to support that meaning.
- C. Roundabout ahead — Nothing in the passages describes a roundabout warning sign, so that meaning is not covered here.
- D. Do not enter — A do-not-enter meaning belongs to a prohibitive sign, which the handbook describes as a red circle with a line through it, the opposite of a permissive one.
Remember it
Green circle means go ahead and do it; red circle with a slash means don't. Ask which kind of message the sign is giving you.
