Seat belts, child restraints and helmets

Understand the rule, its conditions and how to apply it

What you will learn

  • Explain the purpose of this rule.
  • Apply the procedure and recognise its limitations.

Purpose and essential terms

Restraints reduce the chance that an occupant is thrown against the vehicle interior or out of the vehicle in a collision. Rear-seat occupants also need fitted seat belts; their position behind the front seats does not remove the risk.

A three-point adult belt has a lap section and a diagonal section. The lap portion should sit low across the pelvis and the diagonal section across the shoulder and chest, without twists. Putting the shoulder section under an arm or behind the back defeats its design.

Key idea: Restraints reduce the chance that an occupant is thrown against the vehicle interior or out of the vehicle in a collision.

How to apply the rule

Before moving, check that every occupant has an appropriate seat and restraint. Fasten belts properly and confirm the release mechanisms can be used. Use a child restraint appropriate to the child and follow both its instructions and the vehicle instructions; adult belt geometry does not fit every child.

For motorcycling, use a helmet designed for that purpose, with a suitable fit and the chin strap fastened. A helmet resting loosely on the head can come off when needed. A motorcycle learner may not carry a pillion passenger, even if the passenger has a helmet.

Key idea: Keep the vehicle stationary.

Conditions and easily confused points

The 2012 manual’s child-age definitions are historical and must not be treated as a complete current child-restraint rule. In particular, an old source does not establish that a child below its listed age can travel unrestrained. Current requirements and correct fitting need separate confirmation.

Good restraints do not compensate for poor observation, excessive speed or a damaged windscreen. Occupant protection and collision avoidance work together.

Key idea: Apply the full rule to the actual vehicle, road and conditions.

Worked road situation

A rear passenger says they do not need the fitted belt for a short trip.

  1. Keep the vehicle stationary.
  2. Ask them to fasten the belt correctly and check that everyone is secured.
  3. Begin the journey only after the occupants are appropriately restrained.

Quick recap

  • Keep the vehicle stationary.
  • Ask them to fasten the belt correctly and check that everyone is secured.
  • Begin the journey only after the occupants are appropriately restrained.
