Super-confident Justin had expected to breeze through the test and earn a driver's permit.
That would have allowed him to get behind the wheel of his 16th birthday present - a Range Rover given to him by his mentor, RnB star USHER.
But the teenager, whose hits include Baby and U Smile, failed to make the grade and flew into a strop as his mum tried to take him home.
Justin said: "There was no way I was getting in the passenger seat, bawling like a ten-year-old. She kept calling me as I walked to the corner of the parking lot and stood by the street. I felt every car driving by was taunting me."
The fuming singer admits taking out his disappointment on passing motorists.
Writing in his book First Step 2 Forever: My Story, Justin adds: "Some girl drove by, putting on mascara as she weaved down the boulevard - but she sure had a driver's licence, didn't she?
"Some dude cruised by in a truck, smoking a cigarette, which he tossed on the street like the world was his ashtray.
"I bellowed after him, 'I hate you'! It felt so good. I bellowed at the next guy, 'I hate you too! And I hate you! And I hate you!'"
Justin passed his test a month later in April in Atlanta, Georgia, and has since been seen driving an array of top-of-the-range cars.
