If you fail the Delaware permit knowledge test, you must wait at least 10 days before you can retake it. The current Delaware DMV fee schedule does not list a separate knowledge-test retest charge. You cannot retake it the same day, and the applicable Class D or Level One permit/application period is 12 months. No appeals are allowed.
Who this applies to: This retake process mainly applies to adult Class D applicants and teens who actually need DMV testing. A teen with a current Blue Certificate generally has the DMV written and road-skills tests waived for six months from the certificate issue date. Road-test retakes follow separate rules.
The road-test waiting period starts after you pass the knowledge exam. A failed knowledge-test attempt does not start that road-test clock.
Yes, if you are on a licensing path that requires a DMV road test. You must first pass the knowledge exam, then satisfy the separate 10-day road-test waiting rule.
| Application Path | Base Fee | What Failure Changes |
|---|---|---|
| Level One GDL | $40.00 | The $40 Level One fee applies to the teen GDL path. A current Blue Certificate may mean DMV knowledge testing is not required. |
| General Adult Class D | $50.00 | Failing the knowledge test does not create a separate new application fee while the application remains valid. |
Delaware's current online appointment service is for road tests. A standard knowledge-test retake is handled in person at the DMV; do not use the road-test scheduler as a knowledge-test booking system.
Generally, yes. A current Blue Certificate is accepted in place of the DMV written and road-skills tests for six months from its issue date. If the certificate has expired or another rule requires DMV testing, then the DMV knowledge-test process applies.
How many times can I take or fail the Delaware permit test? Delaware DMV’s current driver manual says you may take the exam again after at least 10 days, but it does not publish a numeric maximum number of knowledge-test attempts. The official guidance does not say you are cut off after two, three, or another set number of failures.
What happens if I fail the Delaware permit test 2 times or 3 times? The same retake rule continues to apply: prepare again and return after the required wait while your application or permit remains valid. If it expires before you complete the required testing, follow the applicable reapplication rules.
Multiple knowledge-test failures do not change the separate waiting-period or fee rules already explained above. Prepare with Shoro AI practice questions before test day so you can go in better prepared and aim to pass the first time.

"The AI mock tests were surprisingly realistic. The explanations for road signs helped me understand the logic, not just memorize. Passed my permit test on the first try!"

"I was struggling with the specific road rules of my state until I used Shoro. The flashcards are a game changer for quick revision before the actual exam."

"The readiness score gives you so much confidence. I knew exactly when I was ready to take the test. Highly recommend Shoro for anyone nervous about their exam."
