Police are still trying to work out how and why a truck became bogged in the centre median strip of the Hume Highway at the weekend.

The truck, carrying large rolls of paper, left the road at Wangaratta and became stuck on the median strip about 4.15am on Saturday.

The driver told police the truck’s load had shifted, forcing the vehicle off the road.

Wangaratta acting Sgt Michael Maley said while no-one was hurt, the incident could have been much worse.

“We’re trying to ascertain what the cause was,” he said.

“If it was a problem with the load shifting, we need to look at that and make sure it doesn’t happen again.

“If he was in the left lane and a car in the right hand lane, it could have been serious.

“That’s why we investigate and see whether we can change anything.”

Sgt Maley said there was nothing to indicate speed or intoxication had played a role.

The highway was closed by VicRoads as a heavy haulage vehicle towed the truck out about 2pm.
