Investigations are underway after the man died in a two-vehicle crash near Nowra.

The annual state-wide Anzac Day blitz began yesterday and sees increased numbers of police patrolling all major traffic routes.

Double demerits will remain in place until Sunday (April 27) for speeding, seatbelt and motorcycle helmet offences.

Traffic and Highway Patrol Commander, Assistant Commissioner John Hartley is reminding motorists to be alert and use caution while travelling throughout the state.

“One death on our roads is one too many. It is so important these types of deaths are prevented by drivers driving to the road conditions,” he said.

“There will be a significant increase in traffic across the weekend as the school holidays wind-up and people start heading home.”

“It is crucial that drivers take care on our roads, remain patient and be courteous to other road users,” he said.

During day one of the operation, police have issued 806 drivers with tickets for speeding and conducted more than 38,000 breath tests resulting in 17 drivers charged with being under the influence of alcohol.

In addition to the fatal crash, 49 people have been injured in 135 major crashes across the state.
