A learner rider has been fined and disqualified from driving for four months after he was detected travelling at 130km/h on the South Arm Highway yesterday.
Police detected the L-Plater at South Arm about 4pm Thursday travelling 50km/h above the designated speed limit of 80km/h.
Inspector Kathy Bennett said travelling at such high speeds put both the rider and other road users at risk.
"This rider was inexperienced and disappointingly put himself, and others, at risk of serious injury or death," she said.
"We're encouraging anyone who witnesses such dangerous driving behaviour to report it to police."
Information can be provided by calling police on 131 444.
