The Colorado Department of Transportation has strict enforcement of the state's Passenger Vehicle Traction & Chain Laws which states:
During the months of September 1-May 31, and if weather conditions require, CDOT can implement Passenger Vehicle Traction and Chain Laws. Motorists will be alerted to an active Traction or Chain Law by highway signage.
Traction Law (Code 15) - During an active Traction Law, also known as a Code 15, motorists will need to have either snow tires, tires with the mud/snow (M/S) designation, or a four-wheel drive vehicle - all tires must have a minimum three-sixteenth inch tread.
Passenger Vehicle Chain Law (Code 16) - During severe winter storms, CDOT will implement a Passenger Vehicle Chain Law, also known as a Code 16 - this is the final safety measure before the highway is closed. During a Passenger Vehicle Chain Law, every vehicle on the roadway is required to have chains or an alternative traction device (like AutoSock).
Fines - Motorists driving with inadequate equipment during a Passenger Vehicle Traction or Chain Law could be fined more than $130. If a motorist blocks the roadway because they have inadequate equipment during a Passenger Vehicle Traction or Chain Law, they could be fined more than $650.

***ESTA – Electronic System for Travel Authorization***
Are you visiting the United States from a Visa Waiver Program (VWP) country and currently do not possess a visitor's visa? If so, you will need to complete an official ESTA application by clicking here. You can apply for this for just yourself, or a group of travelers. (To figure out if you are from a VWP county, click here.) In order to complete the application, you will need a valid passport from a VWP country, a valid credit card or PayPal to pay the application fee of $21. See website for more information and requirements.
The application generally takes about 15-20 minutes to fill out and you can check the status of the application by visiting the same site you applied at. Please complete the application at least 2 weeks-72 hours before your scheduled arrival date into the United States. ESTAs are normally valid for 2 years unless you receive a new passport or other important information changes.
