Spring “Heat Is On” DUI enforcement is underway in Colorado. The spring Heat Is On DUI campaign will last through May 15th. During that time period, the Colorado State Patrol will work in conjunction with local law enforcement, to take as many intoxicated drivers off the roads as possible. Last year, 1,555 impaired drivers were arrested during the 5 week long enforcement period. During April and May of last year, 94 traffic fatalities occurred on Colorado roads, 38 of which were attributed to intoxicated drivers.
