Which traffic signal requires you to stop your vehicle?

• A. Flashing yellow lights
• B. Green lights
• C. U-turn arrows
• D. Solid red lights

Answer: (D)

Red signals require you to stop. When you see a solid red light, you must come to a complete stop before the intersection or crosswalk and wait until the light changes to green (or until another lawful signal allows you to proceed). This rule keeps crossing traffic and pedestrians safe by giving everyone a clear break in movement.

Flashing yellow lights are a warning to slow down and proceed with caution, not to stop. Green lights mean you may go, following the usual right-of-way rules. A U-turn arrow indicates that a U-turn is permitted in that lane when the signal allows it; it doesn’t require stopping by itself unless the signal is red or restricted in other ways.
