More than 150 vehicles were stopped by police on the A90 in Tayside.
About 100 road traffic offences were detected as part of a Police Scotland operation involving several units deployed on the A90 between Fraserburgh and Perth.
Officers recovered controlled drugs, arrested a man on an outstanding warrant and seized eight vehicles.
Road policing sergeant Steve Manson, who led the operation over last weekend, said: “This type of route enforcement on a large scale is now becoming a regular tactic and will continue over the course of the year.
“Our goal is to influence driver and road-user behaviour, reduce road casualties and detect and deter all types of criminality on our roads.”
