A few words about Chain Control...

You can check the current status of chain control on the above map. In the winter time, you may see a pin (most likely on the town of Truckee) which mentions R1, R2, or R3. These are those definitions according to CHP:

  • R1: Chains are required on all vehicles except passenger vehicles and light-duty trucks under 6,000 pounds gross weight and equipped with snow tires1 on at least two drive wheels. Chains must be carried by vehicles using snow tires. All vehicles towing trailers must have chains on one drive axle. Trailers with brakes must have chains on at least one axle.
  • R2: Chains or traction devices2 are required on all vehicles except four wheel/all wheel drive vehicles with snow-tread tires on all four wheels.
    NOTE: (Four wheel/all wheel drive vehicles must carry traction devices in chain control areas.)
  • R3: Chains or traction devices are required on all vehicles, no exceptions.



A few words from me...
This site is a pet project of Ray Fannon.

In addition to being a photography nerd I'm also a real life nerd. Check out my photography and timelapse media. You can buy prints or license videos directly from my site. If you're in the market for a nerd use the contact page on my site. I'm always on the hunt for new projects or things to film.

I built this site to give me an idea, at a glance, what weather conditions are going to look like. One day a friend asked me if there were going to be chain requirements for him while traveling over the passes, so I decided to integrate CHP and NDOT data feeds into a map. This site is powered by the Dark Sky API.

A few years ago I came across the AlertTahoe webcams. This is a pretty cool site (although a bit of a clunky user interface), which shows webcams all over California and Nevada (now Oregon and Idaho too).

Honorable mentions: Is California On Fire?, and Is It Snowing In Portland?. You guys were the inspiration for this site.
