Motorists can expect to see extra police on the roads as part of a statewide blitz on drink driving this weekend.

Operation Drink Drive kicked off on Friday morning and runs through until midnight on Sunday.

Drunk drivers and drug drivers will be the main focus of police while fatigue, speeding, road rule compliance and mobile offences will also be in their sights.

Hundreds of motorists are expected to be breath tested across the central west this weekend.
