Police will carry out spot checks to see if drivers are over the drink limit or impaired by drugs.
Operation Ovaldale is being run by the Western Area Roads Policing Unit which covers Bradford and Calderdale.
PC Andrew Gudgeon said: “Motorists must realise their actions could lead to them being disqualified and in the worst circumstances someone’s death. “Use a designated driver or taxi.”
Last month another project, Operation Orewood, stopped 1,652 drivers across West Yorkshire.
Arrests in Bradford and Calderdale included 208 for no seatbelts, 135 for speeding, 62 for using phones and 19 for drink driving.
