Is this a self service station ?

No

Yes, but the kiosk is always broke down.

There are self service kiosk open 24 hours. And full service with people who do the testing.

Yes there is, it hooks to the diagnostic computer port on your car, the location of which varies from vehicle to vehicle but I believe all vehicle 1999 and newer have them.

There is a self service on the right side of the building but also staffed so that you do not have to do it yourself.
