Victoria Police say almost two-thirds of drug drivers detected in Victoria in the last year were caught during daylight hours.
And more than twice as many were nabbed on a weekday than on the weekend.
The new intelligence comes as police warn they’re out anywhere, any time detecting those driving under the influence of illicit substances.
Every highway patrol car has the ability to test for drugs alongside Victoria Police’s drug bus fleet.
Victoria Police figures show around 5200 of the 8400 drug drivers detected in the last financial year were caught between 6am and 6pm.
It compares with almost 3200 detected between 6pm and 6am.
Friday had the most detections of any day with 1400 ahead of Saturday, Sunday and Thursday.
Victoria Police has been scheduling special daytime and early-morning operations to keep drug drivers on their toes and remind all drivers that police are out testing for drugs around-the-clock.
The force conducts around 150,000 roadside drug tests a year.
Anyone caught drug driving faces heavy fines and a loss of licence.
Police have the power to impound a vehicle for drug driving offences.
