What number is assigned to traffic and transportation information?

• A. 611
• B. 911
• C. 511
• D. 411

Answer: (C)

Three-digit numbers are designated for specific public services. For traffic and transportation information, the assigned number is 511. Calling this line provides real-time traffic conditions, road closures, construction updates, detours, and transit information to help you plan a trip. The idea is to keep travel information separate from emergencies and other services, so you can get timely travel details without tying up emergency lines. Other numbers serve different purposes: 911 is for emergencies, 411 handles directory assistance, and 611 connects you with your phone service provider for repairs or support. That’s why 511 is used for traffic and transportation information.
