Driver's License Test Prep
California Practice Road Signs

What does a diamond-shaped road sign tell drivers?

  1. A.
    Important rules that all drivers must obey.
  2. B.
    Specific road conditions or dangers are ahead. Correct
  3. C.
    A rest area or recreation site is nearby.
The Why

The answer is "Specific road conditions or dangers are ahead."

A diamond-shaped sign warns of specific road conditions or dangers ahead. Choice A carries the 'must obey' description over from the white rectangular regulatory sign, a shape drivers pass repeatedly on the same routes and mentally file next to the diamond.

Why the others miss

The traps in the wrong answers

A. Important rules that all drivers must obey.

Rules that drivers must obey appear on white rectangular regulatory signs, not on diamond-shaped warnings. This answer transfers the regulatory-sign job to the diamond because both shapes appear on the same stretch of highway.

C. A rest area or recreation site is nearby.

Rest areas and recreation sites use rectangular guide signs, not diamond warnings. This answer applies a service-sign meaning to the diamond because any decorated highway shape gets read as a facility marker.
