Lane use lights indicate which lanes are allowed at a given time; what's the purpose?

• A. To indicate which lanes are allowed for use at that moment
• B. To show the speed limit for each lane
• C. To indicate parking restrictions
• D. To indicate pedestrian crossing time

Answer: (A)

Lane use lights exist to tell you which lanes you may drive in at that moment. They guide traffic flow and keep you safe by showing which lanes are open or closed, especially around construction, incidents, or changing road conditions. A green indication means you may use that lane as intended, while a red indication (often a red X) means you must not drive in that lane. This system helps reduce weaving and congestion by coordinating where cars should go, rather than guessing based on signs alone. It isn’t about speed limits, parking rules, or pedestrian times, which are shown by other signals and signs.
