Yes you may report a person driving with children that are not restrained in seat belts.

The Phoenix Police Department has a hotline number set up to take these reports.  If you observe a child under the age of 5 not properly restrained while riding in a car, you can call 1-800-505-2229(BABY). They ask that you leave the following information:

1)       The vehicle license number and state.

2)       The city you are in when you observed the child not being buckled up.

3)       Where the child was sitting in the vehicle.

A packet of useful information will then be mailed to the registered owner stating that their vehicle was observed transporting an unbuckled child. The material describes the hazards of transporting an unbuckled child under the age of 5, and encourages the owner to purchase a child restraint system. However, because the program is designed to provide information to those who might need it most, the information reported is not provided to the police, insurance companies, or to the Arizona Motor Vehicle Division.
