The South Carolina knowledge (permit) test

By the end of this topic you can

• You can name the three subject areas the knowledge test covers.
• You can explain the test-room rules that cause an automatic fail.
• You can choose where to take the test and what it costs.
• You can build a study plan using the manual and SCDMV's free practice app.

What you need to know and understand

• The test covers traffic laws, road signs and driving safety rules, all from the Driver's License Manual.
• You can take it at any SCDMV branch, or with an approved One Stop Driver Training and Testing Program (third-party tester).
• SCDMV asks you to arrive at a branch before 4 p.m. to take the knowledge test.
• Each attempt costs $2 as of November 2026; the permit itself is $2.50.
• No manuals, notes or electronic devices are allowed in the test area.
• SCDMV does not print the number of questions or the pass mark in the manual, so confirm them with SCDMV before test day.
• SCDMV's free SC DMV Driver Exam app gives random practice questions based on the manual.

What the questions are about

Expect questions on sign shapes and colors, traffic signals, right of way, school bus stops, passing, parking, following distance, alcohol and drugs, and South Carolina's own rules such as the teen license limits and the hands-free law. The manual's final section, Test Your Knowledge, has sample questions in the same multiple-choice style.

• State-specific numbers worth learning: signal at least 100 feet before turning, changing lanes or merging.
• Park no more than 18 inches from the curb or edge of the pavement.
• Keep a following distance of at least 4 seconds.
• Dim high beams within 500 feet of an oncoming vehicle and within 200 feet of a vehicle you are following.
• Under 21, a blood alcohol concentration of 0.02 percent or more brings a suspension of at least three months.

Test-room rules that mean an automatic fail

SCDMV is strict about honesty. You will fail the test if you do any of the following, even if your answers are correct.

• Leaving the test room or area before you finish.
• Talking to anyone during the test.
• Bringing anything that could help with answers, including written material or any electronic device such as a phone, laptop or tablet reader.

A two-week study plan

1. Read one or two sections of the manual each day and write down every number you see.
2. Learn sign shapes and colors until you can name a sign from its shape alone.
3. Use the SC DMV Driver Exam app to practice, and reread the manual for any question you miss.
4. Work through the sample questions in the manual's Test Your Knowledge section.
5. The day before, check SCDMV's site for the current fee, documents and test details.

Common mistakes

• Studying another state's rules. South Carolina's teen limits, school bus rules and hands-free law are specific to this state.
• Leaving a phone in your pocket. Any electronic device in the test area is grounds to fail.
• Memorizing practice answers without understanding why. The real test words questions differently.
• Arriving at the branch after 4 p.m. SCDMV asks knowledge test takers to arrive before then.
• Skipping the alcohol and drug section. It is a common source of questions for new drivers.
