Cameras will be used to catch people who talk or text on their phones while driving in New South Wales as part of a new package of measures aimed at reducing the road toll after a summer of carnage.

But the Government has baulked at proposals to use point-to-point cameras which target trucks but not cars, to catch more speeding drivers, despite 392 people being killed on NSW roads in 2017.

Announcing the Government's road safety plan, Premier Gladys Berejiklian said the measures would address speeding, drug and drink driving, truck and driver distraction.

"I don't want to see innocent lives continue to be lost," she said.

"That's why as a Government we are doing everything we can to prevent injury and heartache."

Legislation will be introduced to allow camera technology to be used to enforce mobile phone offences, which are a significant cause of accidents.

Roads Minister Melinda Pavey said cameras could be put in tunnels or overhead bridges that could capture people using their phones, but the technology would need to be trialled.

"What we are saying to the community is we hear what you are saying, that you believe mobile phone distraction is a big problem and we are prepared to trial and look at technology to catch people doing the wrong thing."

She said motorists would be warned before any trials took place in NSW.

Other measures announced in the package include:

All mid-range drink-driving offenders must have breath-testing devices fitted to cars which require negative samples before the ignition starts

Government doesn't want community off side

A proposal to use the same heavy vehicle cameras to detect speeding cars has been abandoned by Cabinet, after opposition from Nationals MPs who feared their constituents would view it as a revenue raiser and a broken promise.

Ms Pavey defended the decision not to use the technology to catch speeding cars, despite horrific crashes in regional areas over summer including near Mollymook, Bendalong and on the Newell Highway at Dubbo.

She said it was important to bring the community along with the Government on the plan.

"I think having respect from the community of what we are doing is very important," Ms Pavey said.

"It's about personal responsibility, we don't want any community to think we are doing this just for revenue raising."

She rejected suggestions the Government was not doing enough to respond to the situation and said it was taking many "sound and solid" measures that would drive the road toll down.

"But the worst thing we can do is turn country people off the conversation that we are having, it needs to be a genuine dialogue."

The Premier said she was open to taking further action, including increasing fines or using point-to-point cameras to catch speeding cars in the future.
