(usually 14 or 16.) Even where sidewalk cycling is not prohibited, adults should ride in the roadway in a legal manner. At intersections, motorists can see bicyclists more easily when they are in the roadway instead of on the sidewalk.
Wearing bicycle helmets are required by law only for children under the age of 17 when riding any non-motorized vehicle (bike, scooter, skateboard, etc.) However, helmets are always recommended for riders no matter their age.
Better education of cyclists and motorists is critical to improve safety. Here are some of the bike safety programs available in New Jersey:
The New Jersey Division of Highway Traffic Safety has produced hang tags with bike safety tips that can be attached to a bicycle. The hang tags have been distributed to police, bike retailers, college campuses, traffic safety organizations, and transportation management associations (TMAs). The tag provides information in both English and Spanish.
