Yes, car seats protect children. But you need the right restraint, fitted properly.

Road transport accidents remain a leading cause of death, with between one and two in every 100,000 Australian children dying on our roads each year. The Conversation

There is no doubt using a restraint protects against harm during a crash. In Australia we have seen steady declines in death and injury among children in cars since the late 1970s, when laws requiring children to buckle up in cars were first introduced.

But just having a restraint available is not enough. In terms of risk of death and injury, the protection provided to children in a crash progressively increases from simply having them restrained, to having them restrained in an age appropriate restraint, to having them restrained correctly in an age appropriate restraint.

One in every two restrained children travelling in cars in NSW has at least one error in how the restraint is being used.

The physics of car crash survival

Modern vehicles are designed to reduce crash forces on occupants by absorbing some of the crash energy. Restraint systems protect passengers in crashes by effectively tying them as tightly as possible to the car. This prevents excess movement, and allows passengers to make the best use of safety features built into modern cars.

These features aim to ensure that in a crash, passengers come to a stop over the longest possible distance, reducing the force and therefore risk and severity of injury in a crash.

But in tying the passenger to the car, it’s important the forces applied to the body are distributed over the strongest parts of the body, and that the motion of the body is controlled. This is where design of child restraints comes in.

Different seats for different kids

Laws were introduced across Australia in 2009 and 2010 that stipulated the exact type of restraint that should be used by children of different ages. The laws vary slightly from state to state, but generally these require:

  • children up to at least 6 months of age use a rearward facing infant restraint
  • children up to at least 4 years use a forward facing child seat with in-built harness, and
  • children up to at least 7 years use a booster seat.

Different sized children need different types of car seats, or restraints.

Since then we’ve seen improvements in the numbers of children using the right type of restraint.

While there has not yet been any rigorous evaluation of the impact of these laws on crash injury, they are linked with a reduction in fatalities. Figures from the Bureau of Infrastructure, Transport and Regional Economics show that before the new laws, on average, about 70 children died every year in Australia in car crashes. The average number of child passengers dying each year is now around 40.

Using the restraint properly

To get the best possible protection in a crash, restraints need to be used correctly. One in every two restrained children travelling in cars in NSW has at least one error in how the restraint is being used.

There are three broad types of errors that occur when children use restraints:

  1. errors in the way the restraint is installed in the vehicle
  2. errors in the way children are secured within the restraint, and
  3. errors that are introduced by children while they travel in the car.

Errors are often present even when parents are confident in their ability to correctly use restraints. Sometimes parents are aware of the errors, but don’t realise the potential negative impact.

The biggest problem is when the error loosens how tightly the child is tied to the vehicle. This includes slack in the belts tying the restraint to the car, or the harness tying the child to the restraint, and when the harness or belt is not placed over the correct parts of the body.

The latter commonly occurs when the harness (or seat belt in a booster seat) is not used correctly either because the parent has not secured the child correctly or the child removes their arms during travel.

The new laws of 2009 and 2010 have been followed by a slight increase in correct use of child restraints. In children aged two to five years in low socioeconomic areas of Sydney, we saw correct use increase from 36% to 47% in 2010, just after the introduction of the new laws.

I need help!

Restraint Fitting Stations, and restraint fitting check days run by local governments and safety stakeholders can help parents make sure restraints are installed correctly, and can also provide advice about how to correctly secure their children within restraints.

We have found that children of parents who had not used these services were twice as likely as other children to be incorrectly restrained. But these services can’t be on hand to check restraints every day when parents need to move children between cars or when the restraint settings need to be modified as children grow.

In these circumstances the best available information is the information supplied with the restraint. But parents currently find this information difficult to use, and difficult to understand. And neither of these measures addresses the interaction between the child and the restraint.

Information supplied with child restraint systems should be be user friendly – for all users, including those with lower levels of English literacy. Restraint systems must also be easier to use. Many current restraints are not intuitively easy to use, and sometimes physically difficult to use correctly.

As child safety advocates we need to shift our focus again. Instead of focusing on encouraging parents to use restraints correctly, let’s focus on working with industry to ensure information supplied with child restraints is comprehensible, and to improve restraint design so they’re actually difficult to use incorrectly.

  • yeah maybe they should make it so that someone officially has to check that the seats are installed safely.

  • I don’t know about all states but in SA Australian Red Cross have staff who know how to fit all types of babyseats etc in vehicles correctly. RAA in SA has special services for this too. Police have attended accidents where a vehicle is a total write-off and babies in properly fitted good quality babyseats have been uninjured. 90% of children injured in car accidents is because of incorrectly installed baby or booster seats, or seatbelts not suitable for the size of the child…or unrestrained completely. the parents of unrestrained are the ones who complain the most according to reports I have heard.

  • Thanks for this post – it is so important.

  • If this is true, then professional installation should be FREE. (with the car seat perhaps). Would should it only be available to those who can afford it, when each life is equally valued?

  • Ours was fitted professionally and the car seat I used saved my sons’ life.

  • We always have our restraint’s fitted by a licensed car seat fitter and follow all the guidlines on when they move to the next seat size or are out of the seat completely-much to the dismay of our 11yo who just got out of the car seat a month before her 12th birthday.

  • We always felt it so important to have our child restraints fitted properly and visited the local VicRoads office to ensure it was correct.

  • My son was struggling to correctly fit his child restraint. So he took it to a professional to be fitted, and had his partners restraint checked at the same time. He said it was good as they showed him stuff he was completely unaware of. RAC check child restraints for free


    • RAC is only in Western Australia isn’t it ? I’m trying to find a free restraint fitting service in NSW.

  • Important article but it is a shame that the photo heading the article shows a child in an American car seat that is also not being used correctly (straps too loose and chest clip incorrectly positioned). It is so important for the media to be presenting good examples of car seat use especially when there was nothing to explicitly state the mistakes being made in that initial photo.

  • We got ours professionally fitted, cheers.

  • Hey I like the idea of the fitting stations. 1 minor problem where is it? maybe your report could have included a list of theses sites in ALL Australian States.
