A woman has received 28 demerit points — enough to have a driver's licence suspended twice over — after a single police stop on the NSW Central Coast at the weekend.

NSW Police said they pulled over the 24-year-old on the Pacific Highway at Ourimbah on Monday afternoon after noticing she was using her mobile phone behind the wheel.

While they spoke with her, officers noticed the car seats her three young children were in were not properly secured.

The children were aged one, three and five.

Police said the younger two did not have their shoulder straps tightened properly.

The woman was issued with four different infringement notices — three for not properly restraining the children and another for using her mobile phone.

She was fined $1,348 and received 28 demerit points — 14 of which were accrued due to double demerits during the Easter long weekend.

Family and Community services also received children at risk notifications after the incident.

Police said they had been unimpressed with drivers at the weekend, and had issued 10,177 infringement notices since Thursday.

NSW Police Assistant Commissioner Michael Corboy said three people had died on NSW roads during the Easter break and lashed out at drivers "acting like an idiot on our roads".

"Even though there have been declines in the number of people detected drink driving and travelling above the speed limit, we are still hearing of examples such as the one from Ourimbah," he said in a statement.
