The Jefferson County Sheriff’s Department has announced it will be conducting sobriety checkpoints on two Thursdays (Oct. 11 and Oct. 18) in the Imperial and Fenton areas. According to the department, sobriety checkpoints increase the opportunity for the apprehension of intoxicated and impaired drivers that would normally escape detection, unless they were observed committing a violation or in a traffic crash.  Jefferson County Sheriff Oliver "Glenn" Boyer advises residents who attend gatherings when alcohol is consumed, to be responsible and have a sober driver take them home.
