Seatbelts

Seatbelts - the facts

Seatbelts greatly reduce the risk of being killed or seriously injured in a road crash.

The gist of it
  • Wearing seatbelts in the front seats of cars became law in Australia and New Zealand during the 1970s. Laws requiring rear passengers to wear seatbelts followed in the years after.
  • Seatbelts do not prevent crashes, but they greatly reduce the risk of serious injury or death if a crash happens.
  • Wearing a correctly fitted and well-maintained seatbelt can reduce the risk of being killed in a crash by up to 50%.
  • Seatbelts need to be worn correctly to provide the best possible protection in a crash. A seatbelt should sit firmly across the hips and chest — not under the arm or behind the back.
  • Children under seven years old must use an approved child restraint.

Why they work

  • Seatbelts help slow the body down at the same rate as the vehicle during a crash
  • Seatbelts help stop people from being thrown from the vehicle or hitting parts of the car interior during a crash or sudden stop
  • Seatbelts help reduce injuries by spreading crash forces across stronger parts of the body, including the chest and hips
  • Modern safety features, including airbags, are designed to work together. Seatbelts help slow the body and keep people in the correct position so they can safely impact with the airbag during a crash

Calling the shots

  • Seatbelt laws are different across Australia and New Zealand. Depending on the age of the passenger, the driver may be legally responsible if someone in the car is not wearing a seatbelt correctly
  • It is important to understand the rules and conditions of your licence
  • Safe drivers help make sure everyone in the car is wearing a seatbelt correctly before driving away

What's at stake?

  • In a crash, the force on a seatbelt can be up to 20 times a person’s body weight. Without a seatbelt, that is the force a person’s body may hit the windscreen, dashboard, steering wheel with
  • Passengers not wearing seatbelts can also seriously injure other people in the vehicle during a crash
  • Failing to wear a seat belt – or making sure passengers are wearing one - can result in a fine, and demerit points in some places

Despite the facts, not everyone chooses to wear a seatbelt every time they travel in a vehicle. Young men are less likely to wear seatbelts, and failing to wear a seatbelt is often linked with other risky behaviours, including excessive alcohol use.

There are still many common myths about seatbelts, but the facts clearly show how important they are.

Myth vs Fact

Fact

Crashes can happen anywhere, including close to home where people often drive most. This also applies on farms, properties, and private roads where people may feel more relaxed about wearing a seatbelt. Unexpected hazards like loose gravel, hidden dips, animals, or rough terrain can still lead to a crash.

Even at lower speeds, sudden stops, bumps, or collisions can cause a person’s body to hit the steering wheel, dashboard, windows, roof, or other passengers with significant force.

Wearing a seatbelt correctly helps reduce the risk of serious harm in a crash.

Fact

Airbags are designed to work together with seatbelts, not replace them.

In a crash, a seatbelt helps slow the body and keeps people in the correct position before they hit the airbag. Airbags can deploy at speeds of up to 300 km/h. Without a seatbelt, a person may hit the airbag too fast or from the wrong position, increasing the risk of serious injury.

Fact

A seatbelt can only protect people properly if it is worn correctly. Wearing a seatbelt under the arm changes how crash forces move through the body and can increase the risk of serious injury.

A seatbelt should sit firmly across strong bones in the chest and hips — not across the neck, under the arm, or behind the body.

Fact

Seatbelts are designed to help keep people safely inside the vehicle during a crash. Being thrown from a vehicle greatly increases the risk of serious injury or death.

Safety Checklist

To protect people properly, seatbelts need to be worn correctly and kept in good condition.

  1. A seatbelt should fit firmly across the chest and shoulder, sitting across strong bones like the collarbone and hips. It should not sit across the neck or face, and never under the arm. Once the seat is adjusted correctly, use the height adjuster to position the seatbelt properly
  2. The seatbelt should lie flat and not be twisted
  3. The webbing should not be frayed, worn, or damaged
  4. The buckle should click securely into place every time
  5. Seatbelts are designed to lock during a crash or sudden stop. Test the locking mechanism by pulling the seatbelt out quickly. It should lock, then retract smoothly when released
