Why should we wear seatbelts in riding a vehicle?
We should wear seatbelts to maintain our inertia.
We should wear seatbelts so that our body will not move if we meet an accident or a force is applied to the brake.
We should wear seatbelts so that we can sleep while travelling.
We should wear seatbelts so if we are in an accident our body doesn’t keep moving at the same speed and in the same direction that the car was going.
