The people who deal with hideous scenes of road trauma are fighting a move to unlimited speed zones.

Surgeons and medical professionals are calling for an end to unrestricted speed zones in the Northern Territory.

On certain stretches of the Stuart Highway between Alice Springs and Tennant Creek, drivers can travel at any speed they want, and the NT Government has pledged to expand the unrestricted speed zones if it wins the upcoming territory election.

The Royal Australasian College of Surgeons (RACP) has launched a video campaign against the expansion of unrestricted zones, saying higher speeds can only bring more injuries.

“In an unrestricted speed zone we're all at risk. Speed limits save lives,” one video says.

The campaign has the backing of leading industry groups, including the Royal Australasian College of Physicians and the Australasian College for Emergency Medicine.

“The [motor vehicle fatality] rate for Australia as a whole is about five deaths per 100,000 people in Australia, per year — that's comparable to France, Germany, New Zealand,” emergency physician Dr James Fordyce says in the clip.

“The Northern Territory rate of deaths in motor vehicle crashes is about 15 deaths per 100,000 people per year, which is comparable to Indonesia, Pakistan or Bhutan.”

The NT Government recently reported on its trial of unlimited speed zones north of Alice Springs, saying 85 per cent of people travelled between 133 and 139 kilometres per hour in the open zone.

The experts say that is a concerning percentage of people to be travelling at such a high speed.

“Also, that other percentage of people who do travel at excess speed are then putting both themselves, and in fact those people travelling within their limits, in danger,” said Dr Phil Carson from the Royal Australasian College of Surgeons.

“Why have an open speed limit if most people are clearly most comfortable travelling around the 130 mark?”

Northern Territory Chief Minister Adam Giles said moving from the previous 130km/h limit to an unlimited zone would require responsibility.

“That now means between Alice Springs and the Ali Curung turnoff, about 335 kilometres of open speed limits where you get the opportunity to drive to your ability, to your cars ability, to the road conditions, and the climate conditions,” Mr Giles said.

“Please drive safely, this is about giving responsibility back to you as the driver.”

NT Transport Minister Peter Chandler says he trusts Territory drivers.

“This is not an open licence to speed because the responsibility comes back to the driver,” Mr Chandler said.

“And we have not seen Territorians really change their habits much at all since we've opened the speed limits.

“The reality is most people may drive just a little bit quicker, but certainly not to the extremes that one might consider.”
