Sample California Road Signs Practice Test Questions & Official Manual Citations (2026)

Below are 4 real sample questions from our California road signs practice test bank. Every question in PassMyDMV cites the exact page and rule in the official California manual so you understand the law behind every answer:

Sample Question 1 · Traffic Signals Official California Manual · Chapter 10 · Page 41

You arrive at an intersection showing a solid red lens. A NO TURN ON RED sign is posted. What must you do?

  • A. Stop and remain stopped until the signal turns green Correct
  • B. Proceed because the sign only applies to trucks and buses
  • C. Stop, then turn right if traffic is clear
  • D. Slow to a near stop and roll through when clear
Why A. Stop and remain stopped until the signal turns green is correct: A solid red lens normally allows a right turn after stopping, but only when no NO TURN ON RED sign is posted. With that sign present, you must stop and stay stopped until the light changes. [Manual: TRAFFIC CONTROLS — Traffic Signal Lights, p. 41]
Manual excerpt (Official California Manual · Chapter 10 · Page 41): “Do not turn if a “NO TURN ON RED” sign is posted.”
Sample Question 2 · Traffic Signals Official California Manual · Chapter 10 · Page 41

A flashing red traffic signal lens means:

  • A. Slow down and continue through without stopping
  • B. Stop and wait until the signal stops flashing
  • C. Stop, then proceed when it is safe — observe right-of-way rules Correct
  • D. The signal is broken; ignore it
Why C. Stop, then proceed when it is safe — observe right-of-way rules is correct: A flashing red lens is treated like a STOP sign. You must come to a full stop, then proceed when safe, yielding the right-of-way as required. [Manual: TRAFFIC CONTROLS — Traffic Signal Lights, p. 41]
Manual excerpt (Official California Manual · Chapter 10 · Page 41): “Flashing Red–A flashing red traffic signal light means “STOP.” After stopping, you may proceed when it is safe.”
Sample Question 3 · Traffic Signals Official California Manual · Chapter 10 · Page 41

A solid yellow traffic signal lens means:

  • A. Speed up to clear the intersection before the red appears
  • B. CAUTION — the red light is about to appear; stop if you can do so safely Correct
  • C. The signal is malfunctioning; treat as a four-way stop
  • D. You have the right-of-way for the next five seconds
Why B. CAUTION — the red light is about to appear; stop if you can do so safely is correct: A solid yellow lens warns that the red light is about to appear. Stop if you can do so safely; if you cannot stop safely, cross the intersection cautiously. [Manual: TRAFFIC CONTROLS — Traffic Signal Lights, p. 41]
Manual excerpt (Official California Manual · Chapter 10 · Page 41): “Solid Yellow–A yellow traffic signal light means “CAUTION.” The red traffic signal light is about to appear.”
Sample Question 4 · Traffic Signals Official California Manual · Chapter 10 · Page 41

You are approaching an intersection and the signal turns solid yellow. You cannot stop safely. What should you do?

  • A. Cross the intersection cautiously Correct
  • B. Make an emergency stop, even if the car behind may hit you
  • C. Accelerate hard to beat the red
  • D. Turn on your hazard lights and pull over
Why A. Cross the intersection cautiously is correct: The manual says to stop on solid yellow if you can do so safely; if you cannot stop safely, cross the intersection cautiously. Accelerating to beat the red is not what the manual directs. [Manual: TRAFFIC CONTROLS — Traffic Signal Lights, p. 41]
Manual excerpt (Official California Manual · Chapter 10 · Page 41): “If you cannot stop safely, cross the intersection cautiously.”
