A brave woman has begged teens not to drink and drive after she was thrown from her car in an alcohol fuelled crash - and left paralysed below the neck.

Melissa Ann, then 18, necked four or five beers with pals before getting behind the wheel of her pickup with her mate in the passenger side.

She slammed on the breaks to avoid an accident and was thrown 75ft through the open window while her truck flipped five times.
