No, it's not possible as major rental companies only authorise fully licenced drivers aged 21 years or over to drive their vehicles. Usually, this option won't work if you are under 21, and you hold only a learner's permit or provisional licence.
VroomVroomVroom has two options if you are unable to rent a car for your driving test. You can borrow a car from someone else or you can look for driving schools.
When borrowing a vehicle from your friend, family member or someone else, make sure to review the below checklist before you go on your road test.
In case you can't borrow a car from anyone, you may call the nearest driving schools in your area and ask if one of their vehicles are available to be hired for your driving test.
