Just wanting to have a moan and have been holding onto it for a while now!

Highschool kids walking to school round by Ormlie Crescent - not only do most of them walk on the road but the past couple of days they have been having play fights and pushing each other off pavement onto the road! Now i am only going at 5-10mph anyway as there are lots of parked cars and children about but i still need to hit my breaks quite reguarly and with kids in the back of my car i am not a happy bunny.

Should i contact the headmaster or not?

Moan over
Thanks
