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.
"It might be something minor like the straps are too low or not tight enough," she said.
"I'm more than happy to help the community."
The Rotorua Parent Centre has also recently opened Rotorua Car Seat Clinic through Facebook.
The clinic was set up to educate and inform the community after Plunket removed the service.
"Currently we are just working through Facebook, but people can arrange seat fittings or get advice from us," Mrs Waitoa said.
