Driver's License Test Prep
California Practice Regulatory Signs

Which two signs may be posted where a driver enters a roadway against traffic?

  1. A.
    KEEP RIGHT and NO PASSING
  2. B.
    STOP and YIELD
  3. C.
    DO NOT ENTER and WRONG WAY Correct
The Why

The answer is "DO NOT ENTER and WRONG WAY"

The manual names DO NOT ENTER and WRONG WAY as the pair posted when a driver enters a roadway against traffic. Drivers who pick KEEP RIGHT and NO PASSING are reaching for signs that separate opposing traffic on a two-lane road, not the pair posted at a ramp entered against traffic.

Why the others miss

The traps in the wrong answers

A. KEEP RIGHT and NO PASSING

KEEP RIGHT and NO PASSING regulate lane use and passing, not entering a road against traffic. This answer reaches for signs that separate opposing traffic on a two-lane road, mistaking them for the pair posted at a ramp entered against traffic.

B. STOP and YIELD

STOP and YIELD govern intersection right-of-way, not entering a road against traffic. This answer defaults to the two most familiar red signs from daily driving, since DO NOT ENTER and WRONG WAY are also red and easy to conflate.
