More than 2,000 people have signed a petition opposing speed limit cuts on rural roads in Tasmania.

The State Government is planning to lower speed limits on some country roads from 100 kilometres an hour to 90.

A parliamentary inquiry heard it is not safe to drive at 100 kilometres an hour on most of the roads and the change is the best way to reduce deaths.

The inquiry's chairman MLC Greg Hall is questioning the merits of the move.

Mr Hall has told ABC Local Radio some deaths on rural roads have not been as a result of speeding.

"In fact, only it would seem a very small percentage and most of those unfortunately incidents have been attributed to, when it's analysed, to inattention not driving to the conditions wet conditions, icy conditions," Mr Hall said.

Orford quarry owner Neil Edwards says the move will cost him time and money.

"Since the woodchip mill closed this has been the issue that has really galvanised people," he said.

"Thousands of people have signed petitions, it really has generated a lot of anger.

"We're just sick of the nanny state approach."

Central Highlands mayor Deidre Flint says she does not want rural speed limits cut in her municipality.

"We don't really have many serious accidents in our area and it really comes down to education," she said.

"I'm on the road a fair bit and, you know, how is reducing the speed limit going to stop somebody passing me on the bend in a road, passing me on double lines when it's not safe?"
