The inspection process comprises two parts: Technical test & Legal test
The technical test is used to evaluate the car’s condition, while the legal test may point out evidences of unreported traffic infractions, such as prominent scratches.
It is advisable to hire a mechanic to take a look at the vehicle before bringing it for inspection.
While the inspection takes place, you will not be allowed stay in the garage or talk to the inspectors. Simply wait till the end of the inspection to collect the report.
If the car fails the inspection, you have 30 days to take a free re-inspection. If the car passes, you may get the report signed and stamped before driving away.
