Defensive Riding

At night, it’s hard to see road hazards, and to anticipate the moves of others: You can’t see where they’re looking, and some may be drunk. Slow down from your daylight speed. To make sure drivers see you when you’re stopped, flash your lights by twitching your handlebars back and forth. And watch cars closely; be ready to get out of their way.

Know Your Route

If you’re new at night riding, take streets where you know the pot-holes and traffic so you can focus on riding in the dark. Also, if you’re not sure about nighttime crime in a neighborhood, ask someone who knows the area—or don’t ride alone.

Night Blindness

Don’t bike at night if your visual acuity’s worse than 20/40 with glasses or contacts, or you can read a far-away sign or address okay in daylight but not at night. See a doctor to be sure.
