Perth has its first driverless on-demand car but passengers will not be able to get a ride until next year.

The RAC unveiled the prototype vehicle - the first in WA and one of the first in the world - on Wednesday afternoon.

The car will be put through its paces at RAC’s facilities before trials start on Perth roads in 2019. Initially they will be without passengers before opening up to the public, who will be able to use an app to order the car in the same way they can order a taxi or Uber.

RAC group chief executive Terry Agnew said as with the driverless buses being trialed in South Perth the cars would include a chaperone who was able to manually stop the cars if needed.

He said Perth was one of just three cities in the world to be trialling the cars by manufacturer NAVYA.

“How we move around is rapidly evolving and being able to test emerging vehicle technologies right here in WA will help us adapt to these changes in the safest way possible,” he said.

The vehicles can carry up to six people and have a maximum speed of 90km/h, although speeds are likely to be capped at 50km/hr during the trial.

The RAC is still talking to the State Government and local governments to decide on a final trial site.
