More than 300 drivers suspected of DUI were stopped in Colorado during the Halloween weekend, according to state officials.

Law enforcement agencies around the state arrested 308 DUI suspects as part of The Heat Is On campaign, according to a Colorado Department of Transportation news release.

Last year, 269 arrests were made during the statewide Halloween campaign.

DUI offenders face up to one year in jail, thousands of dollars in fines and a nine-month license suspension, CDOT said. On average, after fines, attorney fees and an increase in motor vehicle insurance costs, a DUI can cost more than $10,000. Penalties increase for repeat DUI offenders.

“Impaired driving is an issue that law enforcement will continue to take very seriously,” said Col. Scott Hernandez, chief of the State Patrol. “Driving under the influence will be enforced until there are zero impaired drivers on Colorado roadways. The more sober drivers, the more lives are saved.”

Throughout the state, 94 law agencies participated in the enforcement program, including the following with arrests noted: State Patrol, 50 arrests; Denver Police Department, 30; Aurora Police Department, 27; and Colorado Springs Police Department, 26.
