Two lanes of the Princes Highway in West Gippsland are still closed this morning after a B-double fuel tanker jack-knifed to avoid a collision last night.
Two cars crashed on the highway between Darnum and Yarragon after 8:00pm (AEST).
The driver of the B-double swerved to miss them, lost control and jack-knifed onto the median strip.
A man driving one of the cars was flown to the Royal Melbourne Hospital and the other driver was taken to the Warragul hospital.
Traffic is being diverted down the west-bound lanes of the highway.
