MUTCD D9-16d · Guide and destination signs
Truck parking availability at rest area facilities
What it means
Truck parking availability at rest area facilities.
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 D9-16d.)
Practice this on the real test format
Signs are the part of the DMV written test people fail on, because reading them is a skill rather than a fact to memorize. Aprobify drills all 1034 of them, and tells you why each answer is what it is.
