Another male motorist was detected travelling a shocking 105km/h in a 40km zone near a primary school.

The men were nabbed in a sting called Operation Lockdown, which targeted speeding and intoxicated drivers across the region.

Ballarat-based Highway Patrol Acting Senior Sergeant Ben Young said the crackdown involved police from Ballarat and Bacchus Marsh along with State Highway Patrol.

The 33-year-old man who blew five times the legal limit was intercepted along Norman Street at Wendouree about 12.40am on Sunday.

His licence was immediately suspended and his vehicle was impounded.

The 25-year-old man who clocked 105km/h in a 40km/h zone was caught along Leith Street at Redan about 2.30pm on Saturday.

St Aloysius Parish School is located on the street and the speed limit remains 40km/h over the weekend. Police impounded his vehicle.

Acting Senior Sergeant Young said police were concerned about serious speeding, with 10 drivers caught travelling more than 25 kilometres over the speed limit in slippery conditions on Saturday.

In total, Operation Lockdown caught eight impaired motorists.

“One driver was detected with a breath alcohol level of .157 before also returning a positive drug sample. His licence was suspended immediately and his vehicle impounded,” Acting Senior Sergeant Young said.

“Police will continue to run similar operations throughout the area to detect and remove those drivers who continue to place the community at risk.”
