Pull over and sleep .
As a indestructible 18 yr old I went out on a Saturday night then decided the next day to go visit a young lady (600km round trip ) . I had to get back in time for trade school on Monday so while I was buggered I thought I had to push through , I can still remember the window down , air con on ,loud music blaring , the blinks , yawns and head nods.
Of course the obvious happened , I woke up on the grass in the left heading towards some gum trees at 100 km , jerked the wheel right in a panick and ended up rolling 3-4 times and finishing on the other side of the road. ( getting chills thinking about it ) I was lucky I walked away and it was 11pm on a Sunday night on a quiet country road so nobody else got hurt .
Make matters worse my old man had to drive 50km to come and get me ( that was a great phone call ), mum gave me a lecture the next day , my first car was gone and I didn't get anywhere with the young lady
