California Practice Traffic Lights

A steady red traffic light means you must:

  1. A.
    Slow down and proceed if the way is clear.
  2. B.
    Come to a complete stop and remain stopped until the light changes, unless making a permitted right turn on red. Correct
  3. C.
    Yield to cross traffic and then continue.
The Why

The answer is "Come to a complete stop and remain stopped until the light changes, unless making a permitted right turn on red."

A steady red traffic light means STOP. Remain stopped until the light changes; a right turn on red is allowed only where no NO TURN ON RED sign is posted, and even then only after you stop at the stop or limit line, yield for pedestrians, and turn when it is safe. A driver picking A carries the flashing yellow signal's proceed-with-caution instruction across to the steady red, treating two signals printed near each other as one family of rules.

Why the others miss

The traps in the wrong answers

A. Slow down and proceed if the way is clear.

A steady red requires a complete stop, not the slow-and-alert response the flashing yellow signal calls for on the same page of the manual. Applies the flashing-yellow 'proceed with caution' instruction to a steady red, treating the two signals as one family of rules because the manual prints them close together.

C. Yield to cross traffic and then continue.

A red light is not a yield sign; the manual requires a complete stop, not slowing to check for cross traffic before rolling through. Treats the red signal like a yield sign, falling back on the slow-and-scan habit drivers use at unmarked intersections instead of the full stop the manual demands.
