If you fail your permit test, you won't be issued a permit. You will be able to take the KY Permit Test as soon as the next business day, but don't rush it. You should retake the test when you feel confident that you can do well.
The KY Permit Test consists of two sections: rules of the road and road signs. You will need to answer 24 of the 30 rules of the road questions and 8 out of 10 road sign questions correctly in order to pass.
It's a good idea to be familiar with all sections of the KY Driver's Manual. You should be familiar with driving and driving laws, road signs and markings, parking, lanes for turning, round-a-bouts and driving point system.
On the day of your KY Permit Test, you will need to bring your birth certificate, your Social Security Car, your proof of residence and your application form. If you are under 18, you will also need to bring a School Compliance Verification Form and an application form signed by your parent.
If you are under 18, your driver's license application needs to be signed by your parent or legal guardian so it is a good idea for them to accompany you. If your legal guardian is unable to accompany you, you should contact a DMV directly to see if there are other options available to you.
