1. NEVER RIDE ON THE SIDEWALK. Cars on the street cannot see you due to other parked cars and WILL make right or left turn on you. Additionaly, cars coming out of parking lots won't see you on the sidewalk.
2. NEVER RIDE ON OPPOSITE SIDE. Ride on the same direction as cars, make yourself visible.
3. INDICATE ALL TURNS WITH HAND SIGNALS. Be predictable. Don't just turn or otherwise behave unpredictably. Indicate turns, make eye contact and then turn.
4. (Obvious) ACT LIKE A CAR AND DON'T RUN LIGHTS.
