GUIDELINES FOR SAFE DRIVING:

Before children use this vehicle, an adult should carefully evaluate the driving area as well as the child’s ability to drive the vehicle safely. Children should demonstrate the capability to handle the vehicle and operate its controls. Teach appropriate safety rules including the warning below to any child using the vehicle before operating.

  1. Not to be used by children under 3 years of age.
