Driver hurt in Adelaide milk tanker crash

A driver has been trapped in his vehicle and thousands of litres of milk spilt across a major Adelaide freeway after an early morning collision between two trucks.

A B-double milk tanker was hit from behind by another truck on the Southeastern Freeway at about 1.30am, near the Stirling exit, rupturing the 23 thousand litre container.

The 40-year-old driver of the second truck was seriously injured and rushed to Royal Adelaide Hospital.

Outbound lanes of the freeway were closed as HAZMAT crews cleaned up the spill, but traffic is now running in both directions.
