Report or stay out of it. Child safety

[Jenny1231990]

Hi all, need some advice on what I should do and how to go about it.
At my sons school a parent of another child in his class drives like a lunatic when takin her children into school. She blocks people in and never gets out of the car to take her little ones in. Anyway I noticed that for the last couple of weeks her children haven't been in childseats.
The youngest is no more than one, her daughter is 5 and the next one maybe 7. She blocked me in on Friday and all the kids were ushered into the back of the car, she didn't strap them in or do up their seatbelt, she got in and drove off while her 5 year old was hanging out of the window waving at her friends.

I know people will say I should have reported this sooner maybe, but who too and how would I even prove it. It's not like someone will wait up the school to see it for them selves. I am genuinely concerned and can't stop thinking about it.
I wouldn't approach her, no one does yet everyone notices. She blocked an ambulance in the other day and stood talking for 20minutes until she was ready to go.

Any advice would be appreciated. And how or if I go about reporting this.

Report it to the school and/or social care. This may be one piece of evidence in a massive file they have on this woman and it may be the bit that tips it over into being able to do something about it

Jot down number plate next time and ring 101 and tell them as much info as possible such as where she's heading/address ect. She is breaking the law and needs to be reported.

Our head would. Report it anyway, then you'll have done all you could.
