Do Colorado’s I-70 Winter Driving Laws Require Chains or Snow Tires for Safety?

Colorado requires commercial motor vehicles (CMVs) to have chains or studded snow tires on I-70, west of milepost 259, from Morrison to the Utah border. This rule also applies to Colorado Highway 9 (milepost 63 to 97) and Route 40 (milepost 256 to the Utah border) during all weather conditions.

The requirement for snow tires or chains usually activates when road conditions are particularly hazardous. Authorities often monitor weather forecasts and road conditions closely. They issue chain law advisories when necessary. Chain laws may also vary based on vehicle size and type. For example, larger vehicles typically face stricter regulations than passenger cars.

Understanding these laws is crucial for safe winter travel on I-70. Compliance can prevent accidents and help drivers avoid fines. It is essential to be aware of the specific conditions that trigger these requirements and prepare accordingly.

As winter approaches, drivers should consider the best practices for winter driving. This includes not only adhering to chain regulations but also preparing their vehicles for safe travel in snowy and icy conditions.
