The State Patrol says traffic deaths in Colorado have declined 34 percent in the last six years.
Patrol chief Mark Trostel told the Legislature's Joint Budget Committee that serious injuries and fatal crashes have decreased from 12-thousand-340 in 2001 to nine-thousand-220 in 2005.
Statistics for last year were not available.
Trostel says traffic deaths dropped from 522 in 2001 to 345.
Trostel says troopers have targeted dangerous locations and have stepped up patrols during the holidays.
He says people also are driving more safely.
Trostel says "driver distraction" was the most common cause of serious accidents.
Cell phones were the most common culprit.
