[Access] Block editing when Y/N field is not checked.

Hello, i'd like to ask for help regarding Microsoft Access 2013.

First of all sorry for the Brazilian language on the prints i took, but is perfectly fine to solve my doubt.

I took 2 screen shots, the first one is the Form i arranged and the second is what i want to block.

This is the first picture.

This is the second picture. What i want is to block the conections made from the squared field, for example:

Block the editions(gray box) for "Quantos?"(How many), "Marcas"(Brand), "Veículo"(Vehicle) and "Placa"(plate) if the field "Possui veículo?"(Do you have a car?) is not checked.
