Colorado’s winter driving restrictions on a mountain stretch of Interstate 70 will be in full force for nine months beginning Sept. 1 under a bill signed into law Friday by Gov. Jared Polis.
The beefed-up traction law takes particular aim at drivers of two-wheel-drive passenger vehicles. Each September through May, they will face the requirement of having specialized winter tires or carrying traction devices while traveling on I-70 between Dotsero and Morrison. The old traction law had been activated only before and during actual winter weather.
House Bill 1207 also increases the minimum tread depth for tires on all vehicles — including those with four-wheel-drive — from an eighth of an inch to three-sixteenths of an inch.
Though I-70 is the only highway corridor where the increased restrictions will be in effect for nine months a year, they will apply to other corridors when the state activates the traction law for storms.
