In the first crash, which occurred on the Upper Murray Road at Biggara about 3pm on Tuesday, a driver crashed a vehicle in between two large trees.

The man managed to free himself from the car, which was badly damaged and tipped onto its side.

"He was extremely lucky," Sergeant Liam McMahon said.

"He walked out of there with no injuries I believe."

Emergency services were also called to an incident in the Tallangatta Valley on Wednesday afternoon where a woman in her 80s rolled her vehicle multiple times.

Volunteers from the SES were required to remove the woman from her vehicle, which was also extensively damaged.

She suffered leg injuries and was transported to hospital.

In the most recent crash, a log truck rolled on the Shelley Walwa Road in the early hours of Thursday.

The road was blocked as the incident was cleared.

A large number of logs fell from the trailers, onto the side of the road.

The driver was also hospitalised.

Sergeant McMahon said it was concerning to see so many crashes in such a short period of time.

"The causes of the crashes are still being investigated," he said.

"We want people to slow down and pay attention to the road.

"There is a lot of wildlife in the area so people need to watch the road, slow down, and avoid being distracted by their phones."

Meanwhile police also responded to the rescue of a hiker at Tom Groggin in the early hours of Wednesday.

A man became trapped while hiking in the area and raised the alarm using an emergency position device.

The man set off a distress signal, which sent out an emergency alert, and led to the police rescue helicopter being deployed and quickly finding him.

The man was winched out of the area about 4am, suffering from hypothermia.

"Those devices are invaluable," Sergeant McMahon said.

"If you are lost in the bush and use them, we will be able to find you quickly.

"I'd highly recommend people take them with them out into the bush."
