OPERATION Arid kicks off today (Friday, March 5) as police prepare for Victorians to embrace the great outdoors across the Labour Day long weekend.

But police have warned traffic volumes and recreational activities are expected to impact road trauma.

Long-distance road trips, cycling and motorbike riding, day trips and recreational activities, such as camping and hiking in national parks, are all forming part of the predictions for an increase in lives lost on Victorian roads over the weekend.

Officers are expecting a high volume of vehicles heading off the main arterials to travel to campgrounds along feeder roads.

In addition, cyclists and motorcyclists are among the vulnerable across the weekend, with favourable weather conditions expected to see people go for prolonged rides and challenge their ability on unfamiliar roads.

With people able to catch up for celebrations and some events back on around the state, police are also anticipating people will decide to get behind the wheel while impaired by drugs or alcohol.

Operation Arid will run from 12.01am on Friday, March 5 to 11.59pm on Monday, March 8.
