What is the purpose of regulatory signs?
-
A.
They direct you to cities, hospitals, and points of interest
-
B.
They mark active construction and maintenance work zones
-
C.
They warn you about hazards or changing conditions on the road
-
D.
They tell you what you must do or must not do by law Correct
The answer is "They tell you what you must do or must not do by law"
Regulatory signs post the laws you must obey, including speed limits, direction of traffic, turning restrictions, and parking rules. Choice C tempts drivers who lump any safety-related sign under the regulatory category, but warning signs flag hazards and changing conditions, while regulatory signs post the legal duty itself.
The traps in the wrong answers
A. They direct you to cities, hospitals, and points of interest
That describes guide signs; regulatory signs post laws you must obey. This answer reads 'regulatory' as 'regulates traffic flow' and pictures the destination-guiding shields, missing that regulatory signs post the law itself.
B. They mark active construction and maintenance work zones
Work zone signs mark construction; regulatory signs post legal duties you must follow wherever they appear. This answer ties 'regulatory' to visible enforcement and pictures the temporary signs of a work zone, forgetting that STOP, YIELD, and speed-limit signs are regulatory everywhere they stand.
C. They warn you about hazards or changing conditions on the road
That is the job of warning signs; regulatory signs post legal duties like speed limits and turn restrictions. This answer half-remembers that both categories aim at safety and defaults to 'regulatory' without picturing the yellow diamond that would flag a warning sign.
