Miss Bryce said a child being restrained properly was one of the most important things.
"You may be the best driver, but people make mistakes and people in other cars make mistakes," she said.

Miss Bryce has seen the benefits of having children restrained correctly firsthand, having been in a car accident with her own child in the back seat.
Miss Bryce said they were grateful for the support of groups like Road Safety Rotorua who had donated children's car seats and the Rotorua Parents Centre who would be giving away free nappies on the day.
Rotorua Parents Centre child restraint technician Alice Waitoa said their research had shown around 80 per cent of children weren't fitted in their car seat correctly.
