True or False: A driver must be able to decipher color to read a traffic signal.

• A. True
• B. Not applicable
• C. Sometimes
• D. False

Answer: (D)

Reading a traffic signal is not solely about perceiving color. Traffic lights follow a fixed arrangement, so you can identify which lamp is on by its position or the sequence, even if you can’t distinguish colors. In a vertical setup, red is at the top, yellow in the middle, and green at the bottom, so you know to stop, prepare to stop, or go by which lamp is lit. This means a driver can correctly respond to the signal without needing to decipher color, making the statement false. If you can see color, you’ll know the meaning quickly, but the essential action—stop for red, proceed for green, slow/prepare for yellow—can be determined by lamp position as well.
