A man escaped with minor injuries after the Fulton Hogan truck he was driving rolled 50m down a bank into a Brighton creek near Dunedin yesterday.
Emergency services were called when a gutter-cleaning "sludge" truck rolled off McIntosh Rd into Otokia Creek about 4.30pm.
A St John ambulance spokesman said the male driver was transported to Dunedin Hospital with minor facial injuries.
The truck rested in the creek on its passenger side, beeping, hazard lights flashing and its engine running, as a fluid created a rainbow sheen in the creek water.
A truck width of trees and bush were flattened on the bank.
