Traction Law Explained!

I-70 travelers should be aware of Colorado’s passenger vehicle traction and chain laws which are implemented when conditions require it.  When either law is in effect, highway signage will be activated. Without proper equipment, motorists can be fined $130. If your vehicle blocks the roadway, you could be fined more than $650.

•  Traction Law (Code 15) — Motorists will need snow tires, tires with mud/snow (M/S) designation, or a four-wheel drive vehicle — all tires must have a minimum one-eighth inch tread.


•  Passenger Vehicle Chain Law (Code 16) — Every vehicle on the roadway must have chains or an alternative traction device (like the AutoSock).

Not sure if your tires have the required 1/8” tread depth?  Try the simple Quarter Test.  Put George Washington head first into your tire tread.  If you can still see the top of his head, it is time for new tires!

Weekend Travel Forecast
Weather should be generally dry with the exception of Saturday morning where there is a 50% chance of snow.

Friday WB - Traffic is possible from 4:30-8:30 p.m. 

Saturday WB – Expect heavy traffic from 6:30 a.m.-Noon. The peak delay will occur at 8:00 a.m. resulting in approximately 40 minutes extra travel time.  Snowy roads could further extend travel times.  Leave by 6:00 a.m. to get ahead of the crowds.

Saturday EB- Light traffic is likely to build around 2:30 and end around 6:30 pm.  Plan to leave after 7:00 p.m. to avoid peak traffic. 

Sunday WB – Traffic due to volume is unlikely.

Sunday EB – Last year there were zero eastbound delays, but the Broncos were in the Super Bowl.  It is hard to predict how the football game will impact traffic this year, but in 2015 travelers experienced 30 minute delays between 11:30 a.m. and 7:00 p.m. with the worst of the delays occurring at 3:00 p.m.
