511 Traffic Systems

What Does 511 Do?

511, by phone or the Internet, provides up-to-the-minute travel information. Expect to find the latest weather, highway travel conditions (accidents, construction, detours), and public transportation by using 511. Some areas also offer ride-sharing information and other regional details; for example, San Diego's 511 tells you how long the wait at the Mexican border is.

Accessing 511 By Phone

Already on the road? Simply dial 511 for information over the phone. It's the price of a local call―use either a cell phone or a landline. After you dial, you'll hear a menu that may be voice-activated, and a list of choices.

511 on the Web

The state is divided into nine sections on the The CalTrans California Smart Traveler Web site:

• San Diego (also located on the Web at www.511sd.com)

• Southern California

• Ventura

• Bay Area (also located on the Web at www.511.com)

• Yosemite (also located on the Web at www.yosemite.com)

Travelers in the Sacramento region may visit www.sacregion511.org.

At this time, the Central Coast and Central California regions are still unavailable.

511 in Other States

When traveling in the U.S., check to see if 511 is deployed in the state you're in yet. Although the plan was to have a national 511 program, it's been slow to get underway.
