A police dash cam caught the moment a dawdling driver was dangerously hogging the middle lane of the motorway.
The car was travelling at just 45mph along a practically empty stretch of the M6 Toll.
Officers pulled the woman over to advise her on her driving.
The footage, captured near the Norton Canes services in Staffordshire, shows other drivers having to manoeuvre around the roadhog while she continues along the 70mph limit motorway in the middle lane.
At one point a police car goes past on blue lights - but even this wasn't enough to persuade the oblivious driver to move over into lane one.
Central Motorway Police Group (CMPG) took to Twitter to share footage of the incident.
They wrote: "Last night on the M6 Toll at Norton Canes a driver was stopped and reported for due care after being captured travelling in lane two at 45mph when lane one was empty.
"Watch as her actions forced another road user to undertake in order to leave the motorway at the next exit.
"Even @StaffsDogs passing on blues was not enough gentle persuasion to make the driver realise they should have been in lane one.
"Driver was spoken to at Norton Canes and advised about lane and speed discipline "
Web users reacted with dismay to the driver's dangerous actions with one person tweeting: "This is my biggest pet hate. Who are you overtaking there? So stupid."
Linda Craddock added: "More people should be pulled up for this it causes so much frustration with other drivers."
Gruffaloscoot put: "I’m more concerned about the 45mph on an empty motorway."
Gareth added: "See it everyday on the M5 M42 and M40. They are driving so dangerously but they fail to see why! #frustrating"
