Where is a child who does not reach 135 centimetres in height permitted to travel?

A)In any of the rear seats using the adult seatbelt.
B)In a front or rear seat, always using the adult seatbelt.
C)In the rear seat, always using an approved restraint device appropriate to their size and weight.Correct
Minors whose height is equal to or less than 1.35 m must compulsorily occupy the rear seats of the vehicle, always using an approved restraint device appropriate to their size and weight.

There are three exceptions under which minors who do not reach that height may travel in the front seat:
1. When the vehicle has no rear seats.
2. When all rear seats are already occupied by minors with the same physical conditions and it is therefore not feasible to fit all the child seats required at that moment.
3. When it is not possible to install child restraint systems in those seats.

When minors are taller than 1.35 m, they may occupy the front seat using the adult seatbelt.
