US Road Signs Regulatory Signs

What does this Do Not Enter sign require of a driver facing it?

Red circle on a square white background with the words DO NOT ENTER in white above and below a wide white horizontal bar.
  1. A.
    Do not enter the roadway from this direction. Correct
  2. B.
    Yield to oncoming traffic, then enter with caution.
  3. C.
    Enter only if you are a local resident or delivery driver.
  4. D.
    Enter only if driving a passenger car, not a truck.
The Why

The answer is "Do not enter the roadway from this direction."

The sign bars entry from your direction because the roadway ahead is one-way against you or is a restricted entrance; stop, back out safely, or turn around. The tempting wrong answer treats the red square like a yield, telling the driver to pause, look for oncoming, and then go if it looks clear. Yielding does not solve the problem the sign describes: any traffic on the roadway ahead is coming toward you because the roadway only runs the other way.

Why the others miss

The traps in the wrong answers

B. Yield to oncoming traffic, then enter with caution.

Entering after yielding would still put you head-on against traffic already using the roadway in its only permitted direction. This answer reads a full prohibition as a yield-and-merge instruction and assumes oncoming traffic can be worked around.

C. Enter only if you are a local resident or delivery driver.

The prohibition applies to every driver on the road, not just strangers or through traffic. This answer confuses the red square with a Local Traffic Only or No Thru Traffic restriction that a resident may bypass.

D. Enter only if driving a passenger car, not a truck.

The sign restricts every vehicle equally; it never singles out one class. This answer mistakes the red square for a vehicle-class ban like No Trucks and picks a driver the rule supposedly spares.
