While the new traction law might have officially gone into effect, many drivers are still confused by what exactly they need to do to prepare themselves for this season on I-70. Before you start panicking and checking your tires, it’s important to understand what the Traction Law (Code 15) actually requires. The traction law is active at all times (sun or snow) from September 1 to May 31. To be in accordance, all drivers on I-70 must comply with one of the three following:

  • 1: AWD/4WD vehicle AND required minimum tread depth of 3/16"


  • 2: 2WD vehicle AND M+S designated tires OR Winter designated tires OR All-Weather designated tires AND required minimum tread depth of 3/16"


  • 3: 2WD vehicle (without M+S/Winter/All-Weather tires) AND alternative traction device (like chains or an AutoSock, etc.)

For those who have paid close attention to previous iterations of the law, this recent update changed required tread depth from 2/16" to 3/16" for all tires. Failure to drive with the proper combination of vehicle type, tire type, tread depth, and/or traction device listed above will result in fines that can range from $130 all the way up to $650 (with highest fines being imposed for vehicles that spin out and block the road due to lack of appropriate tires). 

As fellow I-70 drivers, skiers, and Colorado residents, it is important that we adhere to these new traction laws to help prevent unnecessary collisions and further traffic delays. Have any spare quarters lying around? Check your tire tread and make sure that you’re set for the season. Spread the word and make sure that friends and family know about the new regulations as well. Let’s have a fun, safe, and easy ski season this year!
