(1) Every person propelling a vehicle by human power has all of the rights and all of the duties applicable to the driver of any other vehicle under this chapter, except as to special regulations in this chapter, and except as to provisions of this chapter which by their nature can have no application.
(2) A person operating a bicycle may not ride other than upon or astride a permanent and regular seat attached thereto unless the bicycle was designed by the manufacturer to be ridden without a seat.
(3)(a) A bicycle may not be used to carry more persons at one time than the number for which it is designed or equipped, except that an adult rider may carry a child securely attached to his or her person in a backpack or sling.
(b) Except as provided in paragraph (a), a bicycle rider must carry any passenger who is a child under 4 years of age, or who weighs 40 pounds or less, in a seat or carrier that is designed to carry a child of that age or size and that secures and protects the child from the moving parts of the bicycle.
(c) A bicycle rider may not allow a passenger to remain in a child seat or carrier on a bicycle when the rider is not in immediate control of the bicycle.
(d) A bicycle rider or passenger who is under 16 years of age must wear a bicycle helmet that is properly fitted and is fastened securely upon the passenger’s head by a strap and that meets the federal safety standard for bicycle helmets, final rule, 16 C.F.R. part 1203. As used in this subsection, the term “passenger” includes a child who is riding in a trailer or semitrailer attached to a bicycle.
(e) Law enforcement officers and school crossing guards may issue a bicycle safety brochure and a verbal warning to a bicycle rider or passenger who violates this subsection. A bicycle rider or passenger who violates this subsection may be issued a citation by a law enforcement officer and assessed a fine for a pedestrian violation, as provided in s. 318.18. The court shall dismiss the charge against a bicycle rider or passenger for a first violation of paragraph (d) upon proof of purchase of a bicycle helmet that complies with this subsection. (4) No person riding upon any bicycle, coaster, roller skates, sled, or toy vehicle may attach the same or himself or herself to any vehicle upon a roadway. This subsection does not prohibit attaching a bicycle trailer or bicycle semitrailer to a bicycle if that trailer or semitrailer is commercially available and has been designed for such attachment.
(5)(a) A person operating a bicycle upon a roadway at less than the normal speed of traffic at the time and place and under the conditions then existing must ride in the bicycle lane or, if there is no bicycle lane on the roadway, as close as practicable to the right-hand curb or edge of the roadway except under any of the following situations:1. When overtaking and passing another bicycle or vehicle proceeding in the same direction.
2. When preparing for a left turn at an intersection or into a private road or driveway.
3. When reasonably necessary to avoid any condition or potential conflict, including, but not limited to, a fixed or moving object, parked or moving vehicle, bicycle, pedestrian, animal, surface hazard, turn lane, or substandard-width lane, which makes it unsafe to continue along the right-hand curb or edge or within a bicycle lane. For the purposes of this subsection, a “substandard-width lane” is a lane that is too narrow for a bicycle and another vehicle to travel safely side by side within the lane.
(b) A person operating a bicycle upon a one-way highway with two or more marked traffic lanes may ride as near the left-hand curb or edge of such roadway as practicable.
(6)(a) Persons riding bicycles upon a roadway or in a bicycle lane may not ride more than two abreast except on a bicycle path. Persons riding two abreast may not impede traffic when traveling at less than the normal speed of traffic at the time and place and under the conditions then existing and must ride within a single lane. Where bicycle lanes exist, persons riding bicycles may ride two abreast if both are able to remain within the bicycle lane. If the bicycle lane is too narrow to allow two persons riding bicycles to ride two abreast, the persons must ride single-file and within the bicycle lane. On roads that contain a substandard-width lane as defined in subparagraph (5)(a)3., persons riding bicycles may temporarily ride two abreast only to avoid hazards in the roadway or to overtake another person riding a bicycle.
(b) When stopping at a stop sign, persons riding bicycles in groups, after coming to a full stop and obeying all traffic laws, may proceed through the stop sign in a group of 10 or fewer at a time. Motor vehicle operators must allow one such group to travel through the intersection before moving forward.
(7) Every bicycle in use between sunset and sunrise shall be equipped with a lamp on the front exhibiting a white light visible from a distance of at least 500 feet to the front and a lamp and reflector on the rear each exhibiting a red light visible from a distance of 600 feet to the rear. A bicycle or its rider may be equipped with lights or reflectors in addition to those required by this section. A law enforcement officer may issue a bicycle safety brochure and a verbal warning to a bicycle rider who violates this subsection or may issue a citation and assess a fine for a pedestrian violation as provided in s. 318.18. The court shall dismiss the charge against a bicycle rider for a first violation of this subsection upon proof of purchase and installation of the proper lighting equipment. (8) No parent of any minor child and no guardian of any minor ward may authorize or knowingly permit any such minor child or ward to violate any of the provisions of this section.
(9) A person propelling a vehicle by human power upon and along a sidewalk, or across a roadway upon and along a crosswalk, has all the rights and duties applicable to a pedestrian under the same circumstances.
(10) A person propelling a bicycle upon and along a sidewalk, or across a roadway upon and along a crosswalk, shall yield the right-of-way to any pedestrian and shall give an audible signal before overtaking and passing such pedestrian.
(11) No person upon roller skates, or riding in or by means of any coaster, toy vehicle, or similar device, may go upon any roadway except while crossing a street on a crosswalk; and, when so crossing, such person shall be granted all rights and shall be subject to all of the duties applicable to pedestrians.
(12) This section shall not apply upon any street while set aside as a play street authorized herein or as designated by state, county, or municipal authority.
(13) Every bicycle shall be equipped with a brake or brakes which will enable its rider to stop the bicycle within 25 feet from a speed of 10 miles per hour on dry, level, clean pavement.
(14) A person engaged in the business of selling bicycles at retail shall not sell any bicycle unless the bicycle has an identifying number permanently stamped or cast on its frame.
(15)(a) A person may not knowingly rent or lease any bicycle to be ridden by a child who is under the age of 16 years unless:1. The child possesses a bicycle helmet; or
2. The lessor provides a bicycle helmet for the child to wear.
(b) A violation of this subsection is a nonmoving violation, punishable as provided in s. 318.18. (16) The court may waive, reduce, or suspend payment of any fine imposed under subsection (3) or subsection (15) and may impose any other conditions on the waiver, reduction, or suspension. If the court finds that a person does not have sufficient funds to pay the fine, the court may require the performance of a specified number of hours of community service or attendance at a safety seminar.
(17) Notwithstanding s. 318.21, all proceeds collected pursuant to s. 318.18 for violations under paragraphs (3)(e) and (15)(b) shall be deposited into the State Transportation Trust Fund. (18) The failure of a person to wear a bicycle helmet or the failure of a parent or guardian to prevent a child from riding a bicycle without a bicycle helmet may not be considered evidence of negligence or contributory negligence.
(19) Except as otherwise provided in this section, a person who violates this section commits a noncriminal traffic infraction, punishable as a pedestrian violation as provided in chapter 318. A law enforcement officer may issue traffic citations for a violation of subsection (3) or subsection (15) only if the violation occurs on a bicycle path or road, as defined in s. 334.03. However, a law enforcement officer may not issue citations to persons on private property, except any part thereof which is open to the use of the public for purposes of vehicular traffic.
