Frequently Asked Questions
What is Caltrans?
The State of California, Department of Transportation (Caltrans) is responsible for the design, construction, maintenance, and operation of the California State Highway System, as well as that portion of the Interstate Highway System within the state's boundaries. Alone and in partnership with Amtrak, Caltrans is also involved in the support of intercity passenger rail service in California, and is a leader in promoting the use of alternative modes of transportation. The current framework of Caltrans was set down by Assembly Bill 69 in 1972.
Can I ride my bicycle on the freeway?
Of the more than 4,000 miles of freeways in California, about 1,000 miles are open to bicyclists. These open sections are usually in rural areas where there is no alternate route. California Vehicle Code Section 21960 says Caltrans and local agencies may prohibit bicyclists from traveling on freeways under their jurisdiction and that they must erect signs stating the prohibition. There are no signs permitting bicyclists on freeways. When a bicyclist is legally traveling on a freeway, he/she may be directed off the freeway at the next off-ramp by a sign that says "Bicycles Must Exit." The freeway will be posted at the next on-ramp with a sign that says "Bicycles Prohibited."
What's a "Sig-Alert?"
"Sig-Alerts" are unique to Southern California. They came about in the 1940s when the L.A.P.D. got in the habit of alerting a local radio reporter, Loyd Sigmon, of bad car wrecks on city streets. These notifications became known as "Sig-Alerts." Later Mr. Sigmon developed an electronic device that authorities could use to alert the media of disasters. Caltrans latched on to the term "Sig-Alert" and it has come to be known as any traffic incident that will tie up two or more lanes of a freeway for two or more hours.
How do I file a claim against Caltrans?
If you feel that you have lost money or property as a result of any action or inaction by Caltrans and your claim is for $10,000 or less, you can file your claim directly with Caltrans. No fee is required for claims against Caltrans which are $10,000 and under. Look up where to file your claim.
If your claim is for over $10,000 or concerns a different department or agency of the State of California, you must file a claim with the Government Claims Program. This program gives you the opportunity to formally demand compensation for your loss, and may lead to a settlement of your claim without the need to file a lawsuit.

What's an HOV lane?
"High Occupancy Vehicle" lane, or car-pool lane. The central concept for HOV lanes is to move more people rather than more cars. Some HOV lanes carry almost half of the people carried on the entire freeway. Regular "mixed-flow" lanes are never converted to HOV lanes. Rather, HOV lanes are always added to existing facilities. Each vehicle that travels on an HOV lane must carry the minimum number of people posted at the entrance signs. Usually that means at least two people, or in some cases three people. Each child counts as an occupant, but pets, infants still in the womb, inflatable dolls or ghosts do not (we've heard 'em all). Violators are subject to a minimum $481 fine. Exceptions: Motorcycles, even those carrying just one person, are allowed to use the HOV lanes. Some HOV lanes are in operation only during certain hours, which are posted. Outside of those hours, they may be used by all vehicles.
