State has a Far Right as Practicable Requirement

Bicyclists must ride as near the right side of the roadway as practicable, though a cyclist may use a full lane other than the right-hand one if it is the only lane available for their route.

Allows Two Abreast Riding

Bicyclists may ride no more than two abreast, except on paths or roadway sections set aside exclusively for bicycles.

Single File is Required

State law caps group riding at two abreast rather than requiring single file; riding more than two abreast is allowed only on paths or roadway sections reserved exclusively for bicycles.

Has a Safe Passing Law

A motorist must maintain a safe operating distance when passing a bicyclist, but state law does not set a specific minimum passing distance in feet, unlike SD's three/six-foot rule.

Helmets are required on the road

South Carolina's only statutory helmet requirement applies to riders and passengers under 21 on a "two-wheeled motorized vehicle" (motorcycle/moped) under § 56-5-3660. No statute requires a helmet for an ordinary pedal bicycle rider of any age.

If Bike Lanes are present, they are required ( except when unsafe )

Where a bicycle lane is provided alongside a roadway, a bicyclist must ride in it, except when passing another cyclist or avoiding an obstruction; motorists may not block the lane. A cyclist may use the roadway instead when only a recreational bicycle path (not a lane) is adjacent.

Riders may use the sidewalks

South Carolina has no bicycle-specific statute addressing sidewalk riding. The general sidewalk-driving ban in § 56-5-3835 applies only to a "vehicle," and § 56-1-10(28) expressly excludes devices moved by human power (including bicycles) from that definition, so the ban does not reach bicycles. Local governments may adopt their own ordinances on the subject.

Does the Impeding Statute Apply to Bikes

South Carolina's impeding-traffic statute is limited by its own terms to a "motor vehicle" and does not reach bicycles. Bicyclists are separately capped at two abreast under § 56-5-3430(D), but that is a group-size limit, not an impeding-traffic duty. Title 56's definitions put a human-powered bicycle outside both "motor vehicle" and "vehicle" itself, and the statute that gives bicyclists the duties of a vehicle driver extends only those that by their nature can apply to a bicycle.

Whether cyclists may treat stop signs as yield signs (the "Idaho stop").

Effective May 18, 2026, cyclists approaching a stop sign must slow down, stop only if needed to avoid an immediate hazard, then may proceed with caution while yielding to pedestrians and other traffic (§ 56-5-3530). At a red light, a cyclist may proceed after a complete stop and yielding to oncoming traffic that is an immediate hazard, and may turn right without stopping after slowing and yielding (§ 56-5-970(C)(6)).

Restrictions exist on e-bikes and usage

An "electric-assist bicycle" or "bicycle with a helper motor" is treated as an ordinary bicycle — with no license, registration, age, or extra helmet requirement — only if it meets statutory limits: two or three wheels, operable pedals, a motor of 750 watts (one horsepower) or less, a top motor-assisted speed under 20 mph, a required wattage/speed label, and a motor that disengages when the brakes are applied or pedaling stops. A device outside those limits is not covered by this treatment.

Allows the concept of Contributory Negligence that allows any contributory fault resuls in 'no fault'

South Carolina replaced its common-law contributory-negligence bar with modified comparative negligence in Nelson v. Concrete Supply Co. (1991): a plaintiff may recover only if their fault is not greater than the defendant's (a 51% bar), with damages reduced by their own share of fault. This rule comes from case law, not a statute.
