Police are urging motorists to take extra care on our roads during the June long weekend after three lives were lost on the first two days of Operation Stay Alert.
During the four-day operation, officers are targeting speeding, mobile phone use, seatbelt and motorcycle/helmet offences, alcohol, drug-affected drivers and fatigue.
A 25-year-old Bomaderry man died and another man was critical on Saturday after the car they were travelling in crashed into a tree at Berry.
On Friday, a 91-year-old man lost his life in a four-vehicle crash north of Crookwell and a 34-year-old male motorcycle rider died after he was involved in a crash involving a truck in Riverstone.
Assistant Commissioner Michael Corboy of the Traffic and Highway Patrol Command said he was disappointed with some driver behaviour.
"We have already seen a number of motorists take unnecessary risks on the road this long weekend," Assistant Commissioner Corboy said.
"After the recent wet-weather conditions, we don't want to see an increase in road trauma following the conclusion of this operation," he said.
"Road fatalities have a tragic effect on everyone involved, from the families who must grieve a loved one, to the police who attended the crash, and the communities who have lost one of their own."
"It's simple: slow down and stay alert."
Operation Stay Alert commenced at 12.01am Friday and concludes at 11.59pm Monday, with double demerits in force throughout the period.
