To obtain your South Dakota DMV driver’s permit, you must pass a vision screening and the written permit knowledge test. If you’re under 18, you don’t have to pass the knowledge test if you completed an approved driver education course within the past year. The test consists of 25 multiple-choice questions covering traffic laws, safe driving practices, driving under the influence, vehicle inspection, emergencies, and sharing the road, as outlined in the state’s South Dakota DMV 2026 Driver’s Manual. To pass, you must score at least 80% (20 out of 25 questions).
Our free online South Dakota DMV permit practice test – often called the written or knowledge test – is current for May 2026. It mimics actual exam conditions and provides immediate feedback on any missed questions.
Once you’re ready to apply for the permit, go to the DMV with proof of identity (birth certificate, passport), your Social Security card, two proofs of residence (utility bill, bank statement), and signed consent from a parent or guardian (in person) if you’re under 18. Submit the documents, pass a vision screening, pay the fee, and pass the official written test.
If you fail the knowledge test, you must wait until the next business day and pay a retest fee for every three attempts.
The Instruction Permit is the first phase of South Dakota’s Graduated Driver’s License (GDL) program for drivers under 18. You can apply as early as age 14, but must drive accompanied by a licensed driver who is at least 18 years old. After turning 16 and holding your instruction permit for 180 days, you can apply for a restricted minor’s permit. This permit allows you to drive alone, but only from 6:00 AM to 10:00 PM (with some exceptions for school, work, or church events). You must also have completed an approved driver education course and have no traffic convictions for the past six months. You can apply for your full license at age 16, provided you’ve held the restricted minor’s permit for six months with no traffic convictions.
If you’re over 18, you must obtain an instruction permit and then pass the road test to upgrade to an unrestricted license.
South Dakota permit test: quick facts
What to expect at the DMV
Where South Dakota test-takers struggle most
Based on 1,872 South Dakota learners who practiced on our site in the last 30 days. 47% pass our practice tests, with an average first-try score of 71%.
South Dakota's traffic law questions cover a wide range of violations, from seatbelt rules to point accumulation thresholds. The state uses a 22-point system - reaching 22 points within any 12-month period triggers a suspension. Points expire after one year if no new violations occur.
Warning signs in South Dakota are diamond-shaped and yellow, alerting drivers to upcoming hazards such as curves, intersections, or reduced clearances. Many test-takers confuse warning signs with regulatory or guide signs. The shape alone identifies the sign category before the symbol or text is readable.
South Dakota has a 3-foot minimum passing clearance law for bicyclists - drivers must provide at least 3 feet of lateral distance when passing a cyclist. Farm equipment and slow-moving vehicles frequently share rural roads and must display a reflective orange triangle on the rear. Failing to slow appropriately for these vehicles is a common error.
Passing on the right is only legal in South Dakota when the vehicle ahead is making a left turn and there is a paved shoulder or second lane available. Passing on a hill crest or within 100 feet of an intersection is prohibited. You must signal before every lane change, not just when merging onto highways.
If your brakes fail, the correct sequence is to pump the brake pedal rapidly to build pressure, downshift to lower gears to use engine braking, and use the parking brake as a last resort. Steering into an uphill or a guardrail can also help slow the vehicle. Cutting the ignition is not recommended as it locks the steering wheel on some vehicles.

South Dakota-specific rules you must know
Rules that are unique to South Dakota or differ from most other states
South Dakota is one of only six states that allows a learner's permit at age 14, alongside Alaska, Arkansas, Iowa, Kansas, and North Dakota. The permit restricts driving to daylight hours with a licensed adult supervisor. This early access is especially common in rural agricultural communities.
Teens under 18 who complete an approved driver education course within the past year are fully exempt from the written knowledge test. They can apply for a permit without taking the exam. Completing driver ed also cuts the mandatory holding period from 275 days down to 180 days.
South Dakota is one of a small number of states where the adult seatbelt law is a secondary offense - an officer cannot pull you over solely for not wearing a seatbelt. However, for drivers and passengers ages 14-18, the seatbelt law is a primary offense and officers can stop a vehicle for that reason alone.

How many hours of supervised driving must an Instruction Permit holder under 18 complete before upgrading to a Restricted Minor's Permit or Operator's License in South Dakota?
Show answer & explanation
Correct answer: B - 50 hours, including 10 hours in inclement weather and 10 hours after dark
Permit holders under 18 must log 50 hours of adult-supervised driving. Of those, at least 10 must be in inclement weather and 10 after dark. The inclement-weather requirement is uncommon among states. *See "Types of Driver's Licenses and Driver's Permits," Instruction Permit (Under 18 years of age), p. 8.*
- Question 2 of 7
Under South Dakota's Restricted Minor's Permit, what hours may a minor drive without a parent or legal guardian in the vehicle?
Show answer & explanation
Correct answer: B - 6 a.m. to 10 p.m.
Between 6 a.m. and 10 p.m., a Restricted Minor's Permit holder may operate a vehicle with the parent's or guardian's permission but without them present. From 10 p.m. to 6 a.m., a parent or legal guardian must accompany the minor and sit beside the driver. Exceptions exist for direct travel to and from school, church, or work events. *See "Restricted Minor's Permit," restrictions section, p. 8.*
- Question 3 of 7
A driver accumulates 15 points in a 12-month period on their South Dakota driving record. What happens?
Show answer & explanation
Correct answer: C - They are subject to a driver license suspension
The point system triggers a license suspension at 15 points within any 12 consecutive months, or 22 points within any 24 consecutive months. A first suspension lasts 60 days, a second is 6 months, and any subsequent suspension is 1 year. *See "South Dakota Point System," p. 14.*
- Question 4 of 7
When overtaking a bicyclist on a road with a posted speed limit above 35 mph, what is the minimum separation required by South Dakota law?
Show answer & explanation
Correct answer: D - 6 feet
SDCL 32-26-26.1 sets a two-tier passing distance for cyclists. At posted limits of 35 mph or less, drivers must allow a minimum of 3 feet between the right side of their vehicle and the bicycle. When the posted limit is greater than 35 mph, drivers must allow a minimum of 6 feet of separation. Violating this law is a Class 2 misdemeanor. *See "Passing - Overtaking bicycle," SDCL 32-26-26.1, p. 43.*
- Question 5 of 7
What is the minimum light transmittance required on the front side windows of a passenger vehicle in South Dakota?
Show answer & explanation
Correct answer: C - 35%
Windshields, side wings, and front side windows near the driver's seat must allow at least 35% light transmittance (SDCL 32-15-2.4). Rear windows have a lower threshold at 20% (SDCL 32-15-2.5). No film may be applied to the windshield below the AS-1 line (SDCL 32-15-2.9). Enforcement allows a 9% tolerance on measurement readings.
Source: SD Driver Manual, Windshield & Windows, p.21 - Question 6 of 7
What does South Dakota's window tint law allow for the front side windows of a passenger vehicle?
Show answer & explanation
Correct answer: B - Light transmittance may not be reduced below 35%
Windshields, side wings, or side windows forward of or adjacent to the driver's seat may not have their light transmittance reduced below 35%. Rear windows have a separate, more lenient standard of 20%. No sun screening devices may obstruct the driver's clear view through the windshield. No film may be extended downward beyond the AS-1 line or more than the lowest point of the sun visor of the motor vehicle. *See "Windshield & Windows," SDCL 32-15-2.4, 2.5, 2.9, p. 21.*
- Question 7 of 7
On South Dakota roads with a posted speed limit of 35 mph or more, how far back must you stay behind a snowplow that has its red or amber lights on?
Show answer & explanation
Correct answer: C - At least 200 feet
Snowplows are wide and throw up dense clouds of snow that cut visibility. You must stay at least 200 feet behind a snowplow when its red or amber lights are on and the posted speed limit is 35 mph or more. *See "Winter Driving Safety Tips - Give snowplows room," p. 64.*
