Starting Wednesday, May 19 at 6:30 p.m. at the Eternal Flame at Daley Plaza, a silent procession of bicyclists will honor those who have been killed or injured while biking on public roadways, according to the Active Transportation Alliance.

The ride aims to raise awareness that cyclists have a right to share the roads. The 10-mile route passes the sites of crash victims, which are marked by "ghost bikes" -- bikes painted white. Cyclists are encouraged to wear helmets and use bikes equipped with headlights, since the ride will probably continue past dusk. All cyclists are asked to ride no faster than 12 mph and remain silent, and to wear black arm bands in solidarity with victims or red arm bands to signify a personal injury. The event is free, but a one-dollar donation is recommended for a Ride of Silence pin. This is part of a global event.
