A temporary speed limit posted in a work zone applies:
-
A.
At all times the sign is in place Correct
-
B.
Only when workers are present
-
C.
Only from 7 a.m. to 5 p.m. each day
-
D.
Only when equipment is operating
The answer is "At all times the sign is in place"
The posted work zone speed limit applies at all times, even when workers are not visible. The most common mistake is to treat the lower limit as conditional on seeing workers; that is not the rule. The reduced limit stays in force until you see an End Work Zone Speed Limit sign or another posted speed limit sign, regardless of who is on the ground.
The traps in the wrong answers
B. Only when workers are present
This is the most common half-remembered version; the manual says the limit applies even if workers are not visible. Misreading: Treats the work zone limit as conditional on visible workers, the exact misreading the manual rules out by stating the limit applies even when workers are not visible.
C. Only from 7 a.m. to 5 p.m. each day
The 7 a.m. to 5 p.m. window comes from the school-hours speed sign rule, not the work zone rule. Misreading: Borrows the 7 a.m. to 5 p.m. window from the School Hours Speed Limit sign rule on p.49 and misapplies it to work zones, which carry no time-of-day limit.
D. Only when equipment is operating
The limit is tied to the posted sign, not to whether construction machinery is currently running. Misreading: Adds an 'equipment running' condition the manual does not include; the work zone speed applies whenever the sign is posted, not only when machinery is active.
