MUTCD D5-12 · Guide and destination signs
Interstate oasis facility
What it means
Indicates interstate oasis facility.
What to do about it
It is a guide sign: guide signs give directions, distances and services. They do not impose a rule, but reading them early keeps you out of last-minute lane changes. (MUTCD D5-12.)
