Use the front and rear blinking lights at all times of the day, wear bright/reflective vest or clothes, and always use a rear view mirror when commuting. Do not "take the lane" and ride in the middle of the lane. Stay to the side and give the cars room and they will respect you. Ignorant cyclist ride in the center of the lane at all times and makes drivers angry. Only take the lane when there is a situation where it seems unsafe for the person behind you to pass.
