PARENTS got more than they bargained for when kissing their kids goodbye at school drop-off on Tuesday morning in the Sutherland Shire, south of Sydney.

When St George Highway Patrol police conducted a blitz on stationary cars along Forest Road at Hurstville between 8am and 9.30am - the cops didn't hold back on handing out infringements to parents.

The officers were so concerned by what they found - that not only did they slap the red-faced parents with hefty fines and loss of demerit points - but the offences have also been named and shamed on the command's Facebook page.

The following offences were detected:

1. A 6 year old female seated in the rear of a sedan with no booster seat

2. A child in a booster seat in the rear of a BMW 4WD with the straps not attached to an anchor point

3. (The very next car) - Another child in a booster seat in the rear of another BMW 4WD with straps not fixed to the anchor point

Police will continue to look out for unrestrained car seats

4. A 9-year-old and 10-year-old child, both seated in the rear of the same sedan not wearing any seatbelts at all

5. A three-year-old seated in the rear of a sedan signalled in to the RBT site. The mother of the child was seen pulling the seatbelt around the child as they came in to the site. The child in any event was not restrained in a five-point harness seat that is required for a child of that age.

"Each driver received an infringement notice for $330 and three demerit points for each child who was not restrained as prescribed," the post said.

"St George Highway Patrol will continue to enforce road safety in and around school zones."
