Humberside Police has been criticised over the time of day and manner in which it decided to breath-test motorists on the outskirts of Brigg.
Coun Penny Smith did not object to officers pulling over drivers on the A18 beyond Ancholme Leisure Centre.
What bothered her was parked police cars blocking one lane of this busy road and causing delays for law-abiding motorists.
Police were not in attendance at Brigg Town Council's latest monthly meeting in the Angel Suite on Monday evening (June 25).
So Coun Smith used 'Police Matters' on the agenda to express her displeasure at the traffic jams that resulted.
The early morning crackdown took place on Thursday, June 21 - the second day of the Lincolnshire Show.
Having raised the issue, Coun Smith said she hoped it would be drawn to someone's attention.
Brigg Blog contacted the Humberside force to see whether it wished to comment. No reply has been forthcoming so far.
