Flashing your headlights at fellow motorists is a common way to remind them to turn on their own headlights, or to dim their high beams. One persistent legend in recent years says that courtesy could get you killed. The heavily circulated story says gang members drive around with their headlights purposely switched off. If you flash your headlights at the gang car, the members do a U-turn, chase the “flasher” until they catch up with him or her, then get out their guns and shoot the driver dead. This is supposedly an initiation ceremony for new gang members.
