Traffic–related fatalities this Memorial Weekend were the lowest they've been in a decade.
The Colorado State Patrol says four people died in Colorado in three fatal accidents.
Troopers say none of the accidents were DUI–related, something that hasn't happened since 2003.
CSP made 230 DUI arrests this weekend, wrote more than 8,500 tickets over the course of more than 24,000 traffic stops.
More than 2,000 of those tickets were for seatbelt violations.
Troopers also made 61 felony arrests, recovered nine stolen cars and filed more than 100 drug charges.
All of the state's 743 troopers worked this weekend.
