On-Hand Pre-Approved Vehicle

There's so many people I've heard of who have failed a test due to their vehicles not passing inspection. So why don't the testing stations have a vehicle on had for these cases? If they aren't being done in for their driving skills then they shouldn't be barred for taking their test if there's another vehicle available for them to use! This option should be available to those who need it.

Now whether or not they should be billed again is another matter.

But for now, people, let them sit the damn test without having to wait another month for a chance of a resit!
