A BILL TO AMEND SECTIONS 56-5-160 AND 56-19-10, CODE OF LAWS OF SOUTH CAROLINA, 1976, BOTH RELATING TO THE DEFINITION OF THE TERM "BICYCLE", SO AS TO CLARIFY THE DEFINITION AND TO EXCLUDE CHILDRENS' TRICYCLES; TO AMEND SECTION 56-5-1810, RELATING TO TRAFFIC REGULATIONS REQUIRING ONE TO DRIVE ON THE RIGHT SIDE OF THE ROADWAY, INCLUDING REQUIREMENTS FOR SLOWER MOVING VEHICLES, SO AS TO FURTHER SPECIFY THESE REQUIREMENTS AND TO PROVIDE THAT THE INTENT OF SUCH REQUIREMENTS IS TO FACILITATE THE OVERTAKING OF SLOWLY MOVING VEHICLES BY FASTER MOVING VEHICLES; AND TO AMEND ARTICLE 27, CHAPTER 5, TITLE 56, RELATING TO BICYCLISTS AND USERS OF PLAY VEHICLES, SO AS TO PROVIDE THAT MOTOR VEHICLES MUST NOT BLOCK BICYCLE LANES AND MUST YIELD TO BICYCLISTS IN SUCH LANES, TO PROVIDE THAT BICYCLISTS ARE NOT REQUIRED TO RIDE ON THE SHOULDER OF A ROADWAY AND TO ALSO PROVIDE THAT A BICYCLIST MAY NOT BE PROHIBITED FROM DOING SO, TO DELETE THE PROVISION REQUIRING A BICYCLIST TO USE A BIKE PATH WHEN PROVIDED, RATHER THAN THE ROADWAY, TO REQUIRE A MOTORIST OVERTAKING A BICYCLIST TO ALLOW A MINIMUM OF FIVE FEET BETWEEN THE MOTOR VEHICLE AND THE BICYCLE, TO DELETE PROVISIONS REQUIRING BICYCLES TO HAVE A BELL OR OTHER AUDIBLE DEVICE, AND TO SPECIFY THE FORM AND EXTENT OF ARM SIGNALS THAT BICYCLISTS MAY USE.
Some of the specific provisions:
Rules are spelled out for use of a designated bike lanes (as opposed to greenways or recreational trails):
Section 56-5-3425. (A) For purposes of this section, 'bicycle lane' means a portion of the roadway or a paved lane separated from the roadway that has been designated by striping, pavement markings, and signage for the preferential or exclusive use of bicyclists.
(B) Whenever a bicycle lane has been provided adjacent to a roadway, operators of:
(1) motor vehicles may not block the bicycle lane to oncoming bicycle traffic and shall yield to a bicyclist in the bicycle lane before entering or crossing the lane; and
(2) bicycles are required to ride in the bicycle lane except when necessary to pass another person riding a bicycle or to avoid an obstruction in the bicycle lane. However, bicyclists may ride on the roadway when there is only an adjacent recreational bicycle path available instead of a bicycle lane.
Taunting is illegal.
Section 56-5-3445. It is unlawful to harass, taunt, or maliciously throw an object at or in the direction of any person riding a bicycle. A person who violates the provisions of this section is guilty of a misdemeanor and, upon conviction, must be fined not less than two hundred fifty dollars or imprisoned not more than thirty days, or both.
There are now clear fines for at-fault motorists who injure a cyclist in an automobile/bicycle crash.
Section 56-5-3500. (A) Except as otherwise provided, in the absence of another violation being cited, a violation of this article by the driver of a motor vehicle is subject to a civil fine of up to one hundred dollars unless a bicyclist is injured as a result of the violation.
(B) In the absence of another violation being cited, a person driving a motor vehicle who violates a provision of this article and the violation is the proximate cause of a:
(1) minor injury to a bicyclist, must be assessed a civil fine of up to five hundred dollars; or
(2) great bodily injury, as defined in Section 56-5-2945, to a bicyclist, must be assessed a civil fine of not more than one thousand dollars.
Notice the mention in the headnote of a five-foot buffer for passing. I can't find that in the bill. The bill went through several revisions, and that may have been eliminated. I do see this provision, which addresses passing distance.
Section 56-5-3435. A driver of a motor vehicle must at all times maintain a safe operating distance between the motor vehicle and a bicycle.
Also note the clearly defined duties a cyclist has for signaling his or her intent to turn, slow down or stop:
Section 56-5-3480. A)(1) A bicyclist shall indicate a right turn by extending the left arm upward, by raising the left arm to the square, or by extending the right arm horizontally to the right.
(2) A bicyclist shall indicate a left turn by extending the left arm horizontally.
(3) A bicyclist shall indicate stopping or decreasing speed by extending the left arm or the right arm downward.
(B) A bicyclist is not required to give signals provided for in subsection (A) continuously if the hand or arm is needed to control the bicycle.
(C) A violation of this section is punishable by a fine of twenty-five dollars.
