In the last five years, over 300 people who died in New Zealand crashes were not wearing their seat belt.
Most of those deaths were in 2016.
The Herald, partnered by the New Zealand Police has launched Belt Up - a four day series about seatbelt safety aiming to raise awareness and improve safety for all Kiwis on our roads.
Last year 93 people could have survived the crashes they were in had they been wearing a seatbelt.
Today we find out what the solution is, how do we get every Kiwi belting up?
Today baby Lexie's mother is speaking out about the loss of baby Lexie to shine a light on child restraints.
Mary Navacilla wants other parents to learn from her fatal mistake, she wants to prevent another child being killed, spare another family from the heartache and agony her life is now filled with.
It was May 2014 when Navacilla's life changed forever.
She was in a car heading to Auckland with her husband Titus, baby Lexie, 3-year-old son Gabriel and two friends when their vehicle crashed into a bank at Kopaki near Waitomo.
Navacilla was holding her 12-week-old daughter in her lap and, on impact, the baby was flung into danger.
She suffered severe injuries and died in Starship Hospital the next day.
Tragically, police at the scene of the crash found Lexie's carseat in the boot.
"It was so difficult having to cope up with the loss plus we were trying to heal ourselves from the crash physically, mentally and spiritually.
"Then we had to face the charge for her death, we just didn't know what to do.
"Everyday, I just wake up, take care of my son, go to work, face reality, go home - I just don't feel a thing anymore, I felt like I'm a walking dead person inside."
Navacilla often thinks of Lexie, and what she could have done differently that terribly day.
"She was a very beautiful, good and cuddly little baby," she said.
"She only cried when she was hungry and settled after being fed.
"Not a single day passes that we don't miss her... especially my son Gabriel.. the family prays for her and she's always in our hearts.
"She's our guardian angel, I'm thinking that she's up in heaven looking after us and that she's pain-free."
Child restraints - the law
Under New Zealand law, all children under seven years of age must use an approved child restraint appropriate for their age and size.
International best practice recommends the use of an appropriate child restraint (or booster seat) until your child reaches 148 cm tall or is 11 years old.
Child restraint and medical professionals recommend that you keep your baby in a rear-facing restraint until as old as practicable, at least until they are 2 years of age.
Until a child turns 7 - correctly secure them in an approved child restraint
From their 7th to their 8th birthday - correctly secure your child in an approved child restraint if one is available in the vehicle (and if not, in any child restraint or safety belt that is available)
From 8th birthday to 14 years old - Must use safety belts if available. If not available, they must travel in the back seat.
Over 14 years old - Must use safety belts where they are available.
• Safety belts save lives.
• They support you if you're in a crash or when a vehicle stops suddenly.
• The force on safety belts can be as much as 20 times your weight - this is how hard you'd hit the inside of your vehicle without restraint.
• Wearing a safety belt reduces your chance of death or serious injury in a crash by 40 per cent.
• Whether you sit in the front or the back seat, the risk of serious or fatal injury is virtually the same.
• NZ law requires drivers and passengers in cars and other motor vehicles to wear seat belts and child restraints.
• In the last five years, over 300 people who died in NZ crashes were not wearing their seat belt.
• Many of these people would still be alive today if they were safely wearing their seat belt.
