The bill that would require passenger vehicles to have tires with adequate tread, snow tires or chains on Interstate 70 in the mountains during winter months has advanced in the state House.
Colorado lawmakers are considering requiring snow tires or chains on noncommercial vehicles at all times during winter and spring months, an attempt reduce accidents and mountain traffic.
A winter snowstorm that started on Thursday and continued on Friday led to treacherous driving conditions across Colorado.
There may be record high temperatures outside, but the Colorado Department of Transportation is requiring large trucks to carry snow chains beginning Saturday.
With every passing hour the snow was intensifying Saturday night. On some of the high mountain passes the weather became a major storm event.
