A red and white regulatory sign such as DO NOT ENTER instructs drivers to do what?
-
A.
Follow the sign's instruction exactly. Correct
-
B.
Slow down before proceeding through the marked section.
-
C.
Yield to any oncoming traffic before entering the road.
The answer is "Follow the sign's instruction exactly."
A red-and-white regulatory sign displays a command drivers must follow exactly, so DO NOT ENTER closes that road or ramp to entry with no permitted movement across it. The slow-and-proceed answer is the YIELD-sign habit carried onto every red-bordered sign by drivers who sort signs by color rather than reading the instruction on the sign face.
The traps in the wrong answers
B. Slow down before proceeding through the marked section.
Slowing and proceeding is the YIELD-sign response; a red-and-white regulatory sign like DO NOT ENTER prohibits entry outright rather than allowing cautious passage. This answer carries the YIELD-sign slow-and-proceed habit over to every red-bordered sign instead of reading the specific command the regulatory sign displays.
C. Yield to any oncoming traffic before entering the road.
Yield instructions belong to the red YIELD sign, not to the red-and-white regulatory family that includes DO NOT ENTER, which forbids entry rather than conditioning it on oncoming traffic. This answer sorts every red-bordered sign under the YIELD rule because color is treated as the only cue for telling sign families apart.
