Following last month's arrest days which saw almost 40 people arrested, officers are now using a combination of marked and unmarked vehicles equipped with automatic number plate recognition (ANPR) technology to help them identify suspects.
Police cars are patrolling throughout the county. In the first weekend of the operation, 107 vehicles were stopped.
Area Commander Chief Superintendent Kevin Lambert said: "Following on from Operation Conquest we are now looking to target criminals who use our roads. We know that those who break the law often travel some distance to commit crime and these are the people we are after.
"This operation is not just about arrests, it enables us to build up our intelligence picture about who is using the roads and what they are doing. However I would reassure innocent motorists they have nothing to worry about, this is all about denying criminals the use of the roads."
In a separate development, 19 people were arrested on the county's roads over the weekend for drink driving.
Chief Supt Lambert added: "With patrols taking place across the county we will catch drink drivers and put them before the courts, where they face a lengthy driving ban and all the other problems that go with losing their licence."
