Vehicle is kept abroad
Depending on the local regulations, it is probably possible to undergo a technical inspection in another country, although this inspection will only be valid for that country and on condition that your insurance company accepts it.
The vehicle must be presented at a Belgian inspection centre when it returns to Belgium. We should point out that if the vehicle is late for inspection and depending on the regulations in effect, the price of the inspection will be increased and you will lose your right to claim any bonus on the validity of the certificate.
