My son just told me, one of his friends booked the driving test yesterday, planning to past it, then drives by himself to high school formal today. But, one of his car’s indicator lights did not work, so he failed the test even before starting the engine! $48 test fee gone,ouch…
Other common problems are, the brake light not working, the thread of the tyres too low, etc.
That’s why its smarter to rent the instructor’s car, which is usually much better maintained…
