CHP Traffic gives you quick, real-time access to the traffic incident data provided by the California Highway Patrol. CHP Traffic uses public information provided by the computer aided dispatch office, so it's always up-to-date.

Tired of waiting for talk radio "traffic on the fives?" Want to make sense of what you just heard on the radio by seeing it on a map? GPS traffic info not detailed enough for you? Get instant, accurate, and official CHP traffic info for ALL of California in a portable and easy-to-read format.

Want to check for accidents before you head out so you can choose the better route to take? Live in an area not covered by traffic data in Maps or your GPS so you need to estimate it yourself? Curious as to why your trip to work took an extra 20 minutes today? Need to check whether a Sigalert is still active? This application lets you do it!

CHP Traffic can:

* Use your current location to find traffic incidents near you.
* Show incidents for most metropolitan areas directly on a map (see note below)
* Exchange incident information with other CHP Traffic users via e-mail, SMS, Twitter
* Retrieve detailed information from the CHP on any incident including when it originally occurred, whether CHP units have arrived, and whether the roadway has been cleared
* E-mail full incident logs for later reference
* Gain instant access to the CHP reporting regions you specify as your favorites. Save the regions you pass through during your commute to work, and you'll instantly know what your commute has in store for you
* Look up abbreviations and numeric codes used by the CHP
* Browse all active traffic incidents throughout the state of California


* Incidents for most areas are viewable on a map. (see note below)
* Traffic incidents that are likely to cause significant delay are automatically highlighted in red; highlighting is customizable.
* Exchange links to incidents or full incident logs with friends.
* Incident location display uses a large, bold font for easy reading at a glance.
* Search for incidents using simple phrases or complex route filters; searches update live as incidents are created and retired by the CHP.
* Detailed incident logs are a tap away.

Please note that CHP Traffic groups traffic incidents by the CHP DISPATCH center and/or regional office that is responsible for them. For example, incidents in Goleta or Montecito would be listed under Santa Barbara (the name of the regional office) or Ventura (the controlling dispatch center), depending on where in the app you were looking. Rest assured that, taken together, the CHP district and regional offices listed in CHP Traffic cover ALL of California's highways.

CHP Traffic uses only public information published by the California Highway Patrol. Please note that the CHP does not publish information about certain types of police actions (most notably, police pursuits), and therefore CHP Traffic cannot provide information on these incidents. SantosApps and the CHP Traffic application are not associated with the California Highway Patrol in any way. Always use common sense: never use this or any other application while driving.

What's New

Version 3.5.1

Version 3.5.1 contains the following changes:
• Remove obsolete Rancho Cordova region.
• Add replacement East Sacramento region.
• Add/fix support for iPhone 5.
• Raises minimum supported iOS version to 4.3.

Please note that version 3.5.x is likely going to be the last version that supports iOS 4.x. If you are still using CHP Traffic on a device with iOS prior to 5.0 and have no plans to upgrade, please let us know!

Version 3.5 adds support for the new CHP CAD dispatch system. In particular, incidents in several converted dispatch centers (Los Angeles, Orange County, and San Diego) were being displayed in their parent dispatch center instead of the specific region. For example, South LA incidents were showing up in Southern Division.

As always, please contact us if you have any questions about the app. We are here for you! And special thanks go to those of you who worked with us while we resolved this issue; we appreciate your support!

Please consider an update.


I have used this app almost daily for many years—it’s a habit, but it’s a helpful habit. My phone updated to iOS 11 last night while I was sleeping, and now the app is no longer compatible.
There are many, many of us who love this app & rely on it. It’s simple yet valuable. Please consider an update. Thank you.

Update to newest version


I just did an update to my iPhone to version 11.0.1 and now my CHP app is not compatible. It says you need to update the app. I use this app religiously as does everyone at my office. Any chance you could update it or do we need to find another app? Thank you for you time.

Need update ASAP!

I love this app it’s handy, accurate and very useful if you drive all over the state as I do! However, the new update for iOS 11 is not compatible with the app, please, please fix it. I love the app and would like to able to access it again. Thank you for you time.
