Straight answers to the most common questions about passing the SCDMV motorcycle knowledge exam.
The major rider-education sites report a 30-question motorcycle knowledge test in South Carolina, with 24 correct (80%) to pass. The SCDMV does not publish an official count, and one official snippet suggested 25 — so study every topic rather than trusting a fixed number.
The widely reported passing score is 80% — about 24 of 30 questions correct. Study to be comfortably above that, since the SCDMV does not post an official cut score.
No. It is a separate motorcycle knowledge test based on the SC Motorcycle and Moped Operator Manual. Moped applicants also take this same motorcycle knowledge test.
You need a Class M motorcycle license, or a Class M beginner's permit while you learn. You earn the license by passing a knowledge test and an on-cycle skills test (a vision test may also apply).
You must be at least 15 years old. If you are under 18 you also need a Consent for Minor form signed by an eligible adult, and applicants who are 15 or 16 must first pass a driver education course.
After you pass the knowledge test (and a vision test if applicable) you get a Class M beginner's permit, valid for 12 months. It lets you ride unaccompanied during daylight; at night you must be accompanied by a motorcycle-licensed rider 21 or older with at least one year of experience, within safe viewing distance.
It can replace the on-cycle skills test. The SCDMV accepts a Motorcycle Safety Foundation skills-test certificate if you were tested by an SCDMV-approved, contracted third-party tester within 30 days of applying. You still pass the written knowledge test. Rider training is optional unless you fail the skills test three or more times.
SC requires operators and passengers under 21 to wear an approved helmet (with a neck or chin strap and reflectorized on both sides) at all times. Riders 21 and older may legally ride without one, though a helmet is strongly recommended.
Yes — for younger riders. SC requires motorcycle operators under 21 to wear goggles or a face shield. A windshield does not satisfy this requirement and does not protect your eyes from wind and debris.
Yes. SC law requires the headlight to be on and burning whenever you operate a motorcycle on public streets or highways, day or night — it also makes you far easier to see.
No. SC prohibits operating a motorcycle between lanes of traffic, or between adjacent lines or rows of vehicles (except for police officers on duty). Motorcycles also may not ride more than two abreast in a single lane.
At an intersection controlled by a traffic signal, a motorcyclist may proceed through a steady red light only after coming to a full stop for 120 seconds (two minutes), then treating the signal as a stop sign and proceeding when it is safe and lawful to do so.
Operating with a BAC of 0.05% or higher is a violation, and impairment begins with the first drink — you can be convicted below 0.08%. Riders under 21 face a 0.02% zero-tolerance limit, and refusing a lawful BAC test can suspend your driving privileges for six months.
No. In South Carolina a three-wheel motorcycle may be operated with any class of license except a Class G moped license — a Class M license is not required for three wheels.
A Class M license covers a two-wheel motorcycle, a motorcycle with a sidecar, or a three-wheel motorcycle. If you only want to operate a sidecar rig, you can get a Class M license with an S3 (sidecar) restriction, tested by the SCDMV Master Examiner.
The SC manual recommends new riders keep a four-second following distance behind the vehicle ahead — longer than the two-second rule taught in many states. Open it up to five seconds or more above 40 mph, on slippery roads, when you cannot see past the vehicle ahead, or at night.
At minimum: one or two white headlights, a red taillight, a red brake light, a license-plate light, amber turn signals if built after 1973, a red rear reflector, at least one rearview mirror, a horn, fenders on all wheels, at least one brake, and a working exhaust system. All lighting must be DOT compliant.
Study the SC Motorcycle and Moped Operator Manual published by the SCDMV. The knowledge-test questions are based on it, and it also points you to the road-sign section of the SC Driver's Manual.

An official snippet suggested 25 questions, but the major third-party sites report 30 questions / 24 to pass (80%). The SCDMV manual itself does not publish a count or passing score.
