The Erie County DUI Task Force will conduct a DUI sobriety checkpoint and enforcement initiatives between Friday, Aug. 16 and Sunday, Aug. 18, according to a news release from the Erie County District Attorney's Office.

Officers will be looking for signs of alcohol and/or drug impairment. They will also be checking drivers for proper licensing, which will momentarily delay motorists, the news release said.

The location of DUI checkpoints is picked based on crash statistics and frequency of DUI arrests, according to the District Attorney's Office.

It said the publicized events are meant to deter impaired driving, not to increase arrests. DUI checkpoints and saturation patrols have been proven to lower the number of people killed and injured in alcohol or drug impaired crashes, the District Attorney's Office said.

Pennsylvania has seen an increase in drug-impaired driving crashes in recent years, the news release said. Some people who take prescription drugs could be impaired enough to get arrested for DUI. Marijuana also impairs drivers, especially when combined with alcohol and other drugs.

Funding for the checkpoint was provided by Erie County and a highway safety grant from PennDOT.

Additional checkpoints are planned throughout Erie County during 2019 and 2020. Drivers will see special DUI campaigns around Halloween, Super Bowl Sunday, Cinco de Mayo, Thanksgiving Eve and at local events with identified DUI problems.
