In a Nevada highway work zone, what does an orange speed limit sign mean?
-
A.
It shows an advisory speed slower than the regulatory limit Correct
-
B.
It marks the end of the work zone speed restriction
-
C.
It applies only when construction workers are present
-
D.
It sets the enforceable regulatory speed limit for the zone
The answer is "It shows an advisory speed slower than the regulatory limit"
The manual makes a clean split: orange work-zone speed limit signs are advisory, indicating slower and safer speeds through the zone, while the black-and-white signs are the regulatory limits that carry fines.
The traps in the wrong answers
B. It marks the end of the work zone speed restriction
An orange speed limit sign advises a slower, safer speed through the work zone; it is not an end-of-restriction sign. This answer recalls the orange 'END ROAD WORK' sign that closes a work zone and attaches that end-of-zone meaning to the orange advisory speed sign.
C. It applies only when construction workers are present
An orange speed limit sign advises a slower, safer speed through the work zone; the sign's meaning is not limited to times when workers are visible or present. This answer transfers the school-zone 'when children are present' rule to work zones, treating the orange advisory speed as a workers-present-only limit.
D. It sets the enforceable regulatory speed limit for the zone
Regulatory work-zone speed limits appear on black-and-white signs, not orange ones. This answer swaps the black-and-white regulatory sign role onto the orange advisory sign.
