Teens critical in car smash

THREE teenagers have been critically injured after a car slammed into a stationary bus on a Sydney motorway.

The car, carrying three women and a man, hit the back of the bus in a breakdown lane of the M5 on Sunday.

The female driver, 19, and a female rear passenger, 18, were trapped for a short time before being taken in critical conditions to hospital.

A 19-year-old in the back was also critically injured while the front-seat male passenger, aged 18, was serious but stable. The bus was empty and the driver unhurt.
