You've got options!
Taking your driving test with DPS You can bring any car that meets the requirements (see page 2). Your name doesn't have to be on the insurance. It could be your parent's car, your friend's car, etc. DPS will not allow rental cars though.
Taking your driving test with a driving school You can bring any car that meets the requirements (see page 2). Your name doesn't have to be on the insurance. It could be your parent's car, your friend's car, etc. The driving school might have cars that you can use. We recommend calling the driving school beforehand to double-check.
