Beginning on January 1, 2007, Hawaii will be the 35th state to have a booster seat law. The new law will require children between the ages of four through seven to ride in a booster seat whenever traveling in a motor vehicle. The only exemptions are if the child is over 4’9″ or if the vehicle has lap-only seat belts in the rear seat.
