West Australians could be paying a significantly higher price for speeding after a State Government report found drivers were getting an easier run when compared with motorists in other states.

Key points: WA drivers currently face the third-lowest speeding penalties in Australia

WA drivers currently face the third-lowest speeding penalties in Australia But the proposed changes could see increases of between $50 and $200

But the proposed changes could see increases of between $50 and $200 The Road Safety Minister says higher fines could prompt people to drive more carefully

A review of the Road Traffic Code has found traffic fines in WA were often lower than in other jurisdictions and below the national average.

It has recommended the current penalty for speeding offences of less than 9 kilometres per hour over the limit be increased from $100 to $150.

Speeding between 9-19 kph over the limit would attract a $300 fine, while those speeding by 19-29 kph would be hit with a $500 penalty, each marking a $100 increase.

The fine for speeding at 29-40 kph over the limit would jump to $1,000, an increase of $200.

The Road Safety Commission (RSC) report also recommended increasing penalties for failing to give way at intersections, overtaking offences, following too closely and illegal U-turns.

"Overall, WA remains in the bottom third of Australian jurisdictions in terms of the quantum of penalties," the report stated.

"In some instances, penalties in WA are less than a quarter of the equivalent offence in other jurisdictions."

If the proposed changes were adopted, WA would move from having the third-lowest penalties in Australia to the fourth-highest.

Proposed hikes to be considered: Minister

Road Safety Minister Michelle Roberts said the Government would now consider whether to adopt the RSC's recommendations, but she did not anticipate any change in the near future.

"It would be a lot better if we had an annual increment where things went up by inflation or the CPI. I know that some other jurisdictions have that in place," she said.

"We have slipped behind, particularly for lower-level speeding fines.

I know people do regard these fines as a significant impost and lots of people have difficulty affording them. That is something we will keep in mind."

Mrs Roberts said she supported the report's recommendation not to increase demerit points for speeding offences.

"We are very mindful that people's options in terms of other modes of transport aren't good from everywhere in Western Australia, particularly in regional areas," she said.

"The key thing we want is people to drive more carefully.

"For some people the threat of an increased fine certainly makes a difference.

"[But] it will either require legislative change or regulatory change. That is never quick."

Road fatality rate 'unacceptable': RAC

RAC spokesman Will Golsby said the insurer supported the review of the penalties.

"Any action that has the potential to reduce speed-related deaths and serious injuries should be considered, including increasing penalties where the research demonstrates its effectiveness," he said.

Mr Golsby said WA last year had the worst road fatality rate of any state, at 33 per cent above the national average.
