Drivers need to be more aware of their surroundings and drive to survive is the message from police.

Police across NSW will be targeting all speeding, mobile phone, seatbelt and motorcycle/helmet offences, which will attract double demerit points.

So far this year, 165 people have lost their lives on NSW roads.

Operation Stay Alert, the state's June long-weekend road safety operation, will start at 12.01am on Friday and will run until 11.59pm on Monday.

It is the first long weekend where anyone caught drinkdriving in NSW at any level, including low-range, can lose their licence immediately and face a $561 fine.

Road users should also remember to slow down to 40 kilometres passing emergency service vehicles.

Traffic and Highway Patrol Commander Assistant Commissioner Michael Corboy said the majority of those who've lost their lives on NSW roads so far this year were men.

"Speeding or drink driving doesn't make you more of a man - nor does risking the life of your mates or those you love," he said.

"I am renewing our appeal to passengers, regardless of where you are sitting in the vehicle, to call the driver out on their behaviour. "

Minister for Police and Emergency Services David Elliott said police were not interested in excuses when it came to ensuring the safety of everyone on the road.

"Drivers need to be vigilant, tragedy can strike anywhere, at any time," he said.

"Don't become insulated in your own invincibility, be alert and remain mindful of drivers around you - drive to survive.

"Many people are expected to leave Sydney and head south for the start of the snow season. People are reminded not to try and do too much in a short time frame, placing themselves and their loved ones at risk of being killed or injured in a crash."
