Having adequate snow tires or chains on Interstate 70 is no longer a message solely for truckers. Drivers of passenger vehicles are also being alerted to check their tires before hitting the road. New this year, the Colorado Department of Transportation will be enforcing “Code 15” and “Code 16” on mountain roads.
Code 15 is a traction law that requires all tires to have a minimum one-eighth tread. A Code 16 will be implemented during severe winter driving conditions in which every vehicle on the roadway will be required to have chains or an alternate traction device, such as an AutoSock.
CDOT’s Operation Tire Safe is being implemented to improve safety conditions and to keep traffic moving along the I-70 mountain corridor, especially at Vail Pass and the Eisenhower Tunnel. This follows an instance one day last winter in which 86 percent of the vehicles that caused accidents and delays on I-70 had worn tires. Not sure about your tires? Try the quarter test. Place a quarter in the tread grooves. If part of George Washington’s head is always covered by the tread, you should be fine.
