All used cars registered in the Czech Republic must be inspected (pass a regular technical inspection) in a 2-year period at STK (except brand new cars, the inspection is due after 4 years).
Exhaust emissions test is a part (1st step) of every regular technical inspection (2nd step).
Imported cars must be inspected at STK at first, then you can submit the registration.
Used vehicles must be inspected at STK before making the registration transfer. This inspection is called “evidenční kontrola” (a basic check of VIN, colour, tyre size etc.). The exhaust emissions test is not required.
You don’t have to waste your time and worry about it… I do take care of everything.
I pick up the car and required documents at your home or at the office and bring back when done.
