Police are seeking public information in relation to a motorbike crash at Port Huon on Saturday.

Around 7.44am a 50-year-old motorcycle rider on a blue Suzuki motorbike was involved in a serious motorcycle crash at Port Huon.

Witnesses reported seeing the rider travelling at high speed before losing control and crashing into a concrete culvert and a tree.

The man was airlifted to the Royal Hobart Hospital with serious injuries.

Sergeant Simon Ward said at this stage, excessive speed is believed to be a factor in the crash.

“Motorcycle crashes make up 20 percent of Tasmania’s fatalities and serious injuries and are more vulnerable on our roads as there is little protecting them in the event of a crash such as this.

“Please don’t take any risks if you’re travelling on our roads – we need to make sure everyone gets where they’re going safely.

“We would also like to remind motorists that the speed limit around stationary or slow-moving emergency vehicles that are displaying flashing lights is 40 kilometres per hour,” said Sergeant Ward.

Anyone with information about the crash, or has dash camera footage of the motorcycle prior to, or at the time of the crash is asked to contact Huonville Police on 131 444 or via Crime Stoppers Tasmania at crimestopperstas.com.au.
