Our crash test video shows that even if your car has airbags, you're risking your life if you don't wear a seatbelt.
Although it has been compulsory to wear seatbelts in New South Wales since 1971, each year on average there are more than 30 people killed and 270 injured who were not wearing seatbelts. Many of these deaths and injuries could have been prevented if seatbelts had been used.

In a crash, a person who is not restrained by a seatbelt will continue to travel forward at the speed the vehicle was travelling until something stops them. This could be the steering wheel, dashboard or windscreen. In some crashes, the person may burst through one of the windows and be partially or fully ejected from the vehicle, exposing them to other dangers. They might hit fixed objects or be run over or crushed by their own, or another, vehicle.
In a crash, an unrestrained rear-seat occupant continues to travel forward until his or her progress is impeded, usually by one of the front seats. In a severe crash, the force with which the seat is struck is usually sufficient to cause the seat mountings or seat structure to fail. The front seatbelt must then not only restrain the front-seat occupant, but also the failed seat and rear-seat occupant. Seatbelt failures have been reported under these circumstances, resulting in both front and rear occupants sustaining severe and sometimes fatal injuries. Even if the seatbelt does not fail, the front passenger is subjected to extremely high crushing forces. Front seat occupants have also been fatally injured in this way.
There are seatbelt penalties and demerit points for drivers, including taxi drivers, who do not wear a seatbelt or who fail to ensure their passengers use seatbelts, where available. Passengers aged 16 years and older who do not use an available seatbelt will also be fined. Drivers of a motor vehicle (except a bus) are also responsible for passengers under 16 years old to be properly restrained in seatbelts or approved child restraints. It is also illegal and unsafe to have too many people in a car, especially sitting on the floor or on other people's laps. It is also illegal for passengers to travel in or on the boot of the car, or in a part of a vehicle that has been designed to carry goods. The NSW Legislation website has detailed information under Part 16 of the Road Rules.
Learner or Provisional drivers (P1 and P2) are not allowed to carry anyone who is not wearing a seatbelt or not using a child car seat.
Double demerit points also apply for non-use of seatbelts and restraints during all holiday periods, such as long weekends, Christmas, New Year and Easter.
The four main functions of a seatbelt are to:
- Cause the occupant to decelerate at the same rate as the vehicle in a crash, maximising the distance over which the occupant comes to a stop
- Spread the force of the impact over the stronger parts of the occupant’s body (pelvis and chest area)
- Prevent the occupant colliding with the interior parts of the vehicle
- Reduce the risk of being thrown from the vehicle
Never use a single seatbelt to restrain more than one person. To do so will risk either one or both of the occupants being seriously injured or killed. At particular risk are small children who share a seatbelt when they ride on an adult's lap. In a crash, the child could be crushed between the seatbelt and the adult.
Always ensure seatbelts are adjusted firmly. A poorly adjusted seatbelt will allow the occupant to move forward in a crash and increase the risk of head contact with part of the vehicle interior. In moving forward, the occupant will also experience high seatbelt loads as the slack is taken up.
Seatbelt induced injuries can generally be traced back to incorrectly adjusted seatbelts. Seatbelts should also be adjusted so that the lap portion lies across the bony section of the hips and the sash falls across the chest and mid shoulder. Some belts, where the end anchorages are too high or too far back, can tend to ride up over the front bony parts of the hips. This is unsafe because in a crash it does not protect the abdomen contents or lower spine as well as it should.
Yes, pregnant women should wear a seatbelt at all times. The safest place for the unborn child is in the firmly restrained pouch of the womb. If the mother and womb are left free to impact hard objects inside the car, those blows will be transmitted to the child and severe injury may result. Similarly, if the unborn child’s mother is injured or killed, the child's chances of survival will be considerably reduced. The main cause of foetal deaths in car crashes is the death of the mother. The most effective way for pregnant women to wear a seatbelt is to put the lap part of the belt as low as possible.
It should be positioned under the abdomen, below the front bony part of the hips and across the upper thighs. This will be well below the midpoint of the womb as the baby gets larger. Breast tenderness caused by the sash part of the belt can usually be avoided by passing the seatbelt between the breasts. If this is not the natural line of the sash, a sash guide may be used to improve the comfort of the seatbelt.
