Seven people, including a toddler, have died on NSW roads in two days and police say speed was a factor in half of the crashes.
There were six deadly crashes on the weekend across the state and all but one occurred on regional roads.
A three-year-old girl was killed when the car she was in rolled south of Dubbo on Saturday. Two women in the car, aged 28 and 32, were hospitalised.
Two people died near Temora on Sunday after their car left the road, hit a tree and burst into flames.
Four others were killed in crashes in Port Stephens, Wirrimah, Lucas Heights and Clifden.
NSW Police Assistant Commissioner Michael Corboy said speed played a part in three of the six crashes.
"If you are travelling this summer I implore you to think about the lives around you and the impact your death or injury would have on them," he said in a statement on Monday.
Meanwhile two cameras capable of identifying drivers using their mobile phones have been switched on at two busy locations in Sydney for a three-month trial.
Drivers caught by the cameras, mounted on the M4 near Prospect and on Anzac Parade, will receive a warning rather than a fine during the trial period.
During a month-long test period in October, more than 11,000 drivers were caught on their phones.
The government will make a decision about the long-term deployment of the cameras in early April, after the state election.
