OXFORD — A sobriety checkpoint will take place in town Friday, March 21, police Chief Jonathan Tibbetts said Tuesday.

The four-hour operation will take place at an unannounced time and an unannounced location and with the assistance of officers from Norway and Paris police departments and Maine State Police.

The operation is sponsored through a $10,000 sobriety and speed checkpoint grant from the Maine Highway Department to Oxford police in December.

This is the second sobriety checkpoint the department has conducted with the grant, Tibbetts said.

In January, officers set up a sobriety checkpoint in front of the Oxford Public Safety Building on Route 26 and pulled over 390 motorists, Tibbetts said.

While no arrests were made for driving under the influence, a couple of dozen summonses and written and verbal violations were issued, ranging from operating a motor vehicle after suspension, to driving with a motor vehicle defect. Ten seat belt violations and seven inspection sticker violations were also cited.

Tibbetts said he was somewhat surprised that no drunken drivers were apprehended.

“We try to be proactive,” Lt. Michael Ward said of the effort to reduce drunken driving.

“We try to pick a night when something is happening,” Tibbetts said.
