The RAC wants the number of random breath tests increased so every WA motorist is tested at least once a year.
And they want police officers around the State spending more time on traffic duties.
The recommendations are included in the car insurer's Budget submission to the State Government that aims to "bring WA's road fatality rate down".
RAC general manager of corporate affairs Will Golsby said WA recorded a road death every two days last year so "now is not the time to be complacent".
"Increased police presence on our roads can work as a deterrent for motorists and is more likely to positively change driver behaviour," Mr Golsby said.
"And researchers have indicated that up to one random breath test per licence holder a year can achieve a substantial reduction in accidents."
Last year, WA's road fatality rate was higher than the national rate.
"To come in line with the national rate, 33 additional lives would need to be saved each year," Mr Golsby said.
"This week's State Budget needs to show a renewed commitment to reducing deaths and serious injuries on our roads."
The RAC submission also called for funding to specifically improve safety of motorcyclists.
"Between 2008 and 2013, WA recorded a 47.8 per cent increase in motorcycle registrations - the highest rate of increase in Australia," it said.
"Overall, motorcycles make up 5.5 per cent of licensed motorised vehicles, yet last year they accounted for 15 per cent of the State's road fatalities."
The RAC submission calls for more money to improve traffic light efficiency and a trial of managed motorways including traffic lights on freeway on-ramps.
