What does a solid red traffic signal mean?

• A. Stop completely and wait if necessary.
• B. Proceed with caution if the intersection is clear.
• C. Stop; do not proceed until it turns green and the intersection is clear.
• D. You may turn left on red after a complete stop.

Answer: (C)

Solid red means you must come to a complete stop and stay stopped until the light turns green and the intersection is clear of cross-traffic and pedestrians. You wait behind the stop line and do not enter the intersection on red. Only when the signal is green and the way is clear may you proceed.

This rule protects people crossing the street and prevents collisions with vehicles that have the right of way. Proceeding with caution on red or attempting to move before green would create unsafe situations. Turning on red or left-on-red maneuvers are not allowed under the standard rule, except for specific local exceptions, which you would follow only if legally permitted.
