The incident happened around 7.15am and closed the south-bound lane.

Fire and Rescue NSW Wollongong station officer Greg Faulkner said the 52-year-old man was trapped in his car when crews arrived.

‘‘He was ... stabilised by paramedics and transported to Wollongong Hospital,’’ Mr Faulkner said.  

Mr Faulkner said the crash occurred near a bus depot, and the truck was removed soon after the crash to allow school bus services to continue.

The man is in a stable condition.
