The bonus here is that if the kid gets run over while you are waiting for the police, they are already on their way.

Lol you just do both at once. Pull the kid away from traffic in one hand and call 911 using the other. Goal is to not be seen helping the kid without the call ringing on the other side. Anybody comes charging show them your phone with 911 clearly visible on it.
