L-Platers will need to clock up 50 hours of supervised driving time before they get to their practical driving test, from October 9.
Currently, learners notch up 25 hours, then sit the test and complete another 25 hours.
The changes will see all those hours and a Hazard Perception Test completed before the Practical Driving Assessment.
The 50-hour log book also needs to include five hours of supervised night-time driving to ensure greater learner experience prior to attempting the PDA.
Transport Minister Rita Saffioti says changing the sequence will reduce the complexity of the provisional licence process and align WA with other States.
"It is hoped that the re-sequence will increase the current practical driving assessment pass rate, resulting in more assessment slots being vacant, which will reduce customer wait times for PDA availability," she said.
Existing learner's permit holders will automatically transfer to the new process from October 9.
