## CHPMap Description
Know the road before you drive it.

Live California Highway Patrol incidents statewide — and, for the drive over Echo Summit, Donner, Carson Pass, the Grapevine or Tehachapi, every chain-control checkpoint on your route. See Caltrans' live R-1/R-2 status in each direction and what drivers there are reporting right now: how long the queue is, whether chains are being checked, whether people are being turned around. Plan the drive, see the forecast for when you'll reach each pass, and let Drive mode announce the next checkpoint as you approach.

Trip mode for mountain drives:
- Search a destination and see every checkpoint and CHP incident along the way, in travel order — plus cameras and signs with CHPMap Pro
- Live Caltrans chain-control status per pass, per direction, year-round
- Driver reports on each checkpoint — wait, enforcement, last update — from drivers on the road
- Checkpoint hub: Caltrans status, driver reports and nearby incidents on one screen, plus cameras, weather and signs with CHPMap Pro
- Mountain briefing: pick a departure time and see the whole drive on one timeline — the climb, the forecast when you reach each stretch, snow and possible ice, chain controls and closures — with the source and age of every item
- Compare mountain corridors, like I-80 and US-50, side by side when there's a real choice
- Drive mode shows only the next thing that changes and announces checkpoints and incidents as you approach; follow a trip to get a push when a pass changes
- Ask Siri: "Are chains required in CHPMap" or "Chain controls on 80 in CHPMap"

The live CHP incident map, as always:
- Live California Highway Patrol incidents, statewide, with the full CAD log
- Tap any incident for type, location, time and unit updates
- Tap the bell on any incident to get notified when it's updated or cleared from CHP's list
- Save favorites and share incidents with a tap
- Mountain drive coming up? Make Trip your home screen in Settings ▸ Home screen

Checkpoints and the trip planner are free. CHPMap Pro adds:
- Traffic Cameras — live Caltrans highway camera feeds
- Weather Alerts — NWS zones, color-coded by severity
- EV Chargers — public charging stations
- Rest Areas — Caltrans roadside stops
- CMS Signs — Caltrans changeable message signs
- CHP Radio Areas — area boundaries + radio channel info

Great for mountain and long-distance drivers, daily commuters, fleet and field teams, and anyone who wants a clearer view of the road.

CHPMap is not affiliated with the California Highway Patrol. Incident and map information may be delayed or incomplete — always follow official guidance and road signs.

CHPMap Pro is an optional auto-renewing yearly subscription that unlocks every premium layer — Traffic Cameras, Weather Alerts, CMS Signs, CHP Radio Areas, Rest Areas and EV Chargers — with a 7-day free trial for new subscribers. Existing per-layer subscriptions keep working. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless canceled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple Account settings.

## CHPMap Reviews in United States

### *---- "Useless but not their fault"
It’s not the software, it must be the CHP but a lot of incidents on state  and federal highways are just not appearing on the map. I used to rely on it but can’t anymore. Today there was a major incident on highway 29 in Napa County. It never was on the map. Last week 3 lanes blocked on US 101 in Santa Rosa. Never was on the map. The app is now useless. The incidents are also not appearing on the CHP incidents site, so it’s the CHP’s fault.
-- esanoche, 2019-06-12

### *---- "Push Notifications"
You seem to have to know some kind of ICU programing language just to configure the push notifications. Ther are no instrucitons that I can find on how to do this from the app creator.
-- BSF93920, 2018-08-28

### ***** "Nicely done"
I’ve been using this for years.  It’s very useful for getting accurate up to date info on CHP calls.  I’m not sure what I’d do without it.
-- Taylor Hively, 2018-08-24

### **--- "So frustrating"
Update: I would like my money back if you cannot fix the problem please.  I have removed and downloaded the app 20+ times and still can not get it to work. Thank you for updating but it's still not working!  I'm about to give up.
-- Don't ever stop investigating!, 2014-11-30

### *---- "Still crashes"
Great app on my iOS 7 devices.  Still crashes on my iPhone 6 (iOS 8). With current version (4.0.4) lost ability to send bug report.  Very frustrating.
-- Ohio transplant, 2014-11-30

### *---- "App Crashes"
I paid for this app and now with IOS8 it crashes as soon as I try to open it. Needs to be fixed ASAP. Update did nothing to help! Latest update did nothing. I want my money back.
-- FLTR073, 2014-11-28

### ***-- "Very Frustrated"
Even after 3 updates the app still crashes. U need to find the problem and fix it
-- Kanders0799, 2014-11-27

### *---- "Crashing"
Still crashing after latest update;(
-- Largelefty, 2014-11-24

### **--- "Update still crashes"
I have an iPhone 6 and the app still crashes when I try to load. I have deleted and reloaded with no success on getting it to work. It does work on my iPad with the same operating system.
-- Tricat77, 2014-11-04

### ***** "Good app."
Great upgrade! Need delete old version and reinstall to fix crash.
