In a Nevada highway work zone, what does an orange speed limit sign mean?
-
A.
It carries the same regulatory force as a black-and-white speed limit sign.
-
B.
It is advisory and indicates slower, safer speeds. Correct
-
C.
It applies only when construction workers are physically present.
-
D.
It replaces the state maximum speed limit along the entire route.
The answer is "It is advisory and indicates slower, safer speeds."
The manual states orange work-zone speed limit signs are advisory and indicate slower, safer speeds, while black-and-white speed limit signs are the regulatory posting. The wrong answers confuse the two sign colors, borrow a school-zone "when present" condition, or overstate an advisory sign's reach beyond the work zone.
The traps in the wrong answers
A. It carries the same regulatory force as a black-and-white speed limit sign.
In a Nevada work zone, the black-and-white speed limit signs are the regulatory posting; the orange signs are advisory. This answer assumes every posted speed number carries the force of law, missing the manual's split between regulatory black-and-white signs and advisory orange signs in the same work zone.
C. It applies only when construction workers are physically present.
The manual attaches no worker-present condition to work-zone speed limit signs; the advisory posting applies whenever it is up. Half-remembers the school-zone rule where a lower posted limit only kicks in when kids are crossing.
D. It replaces the state maximum speed limit along the entire route.
An advisory work-zone speed sign applies inside its work zone and does not override any statewide speed limit along the route. This answer reads orange as a higher-priority color that overrides other posted limits, when the manual describes it as an advisory sign scoped to a single work zone.
