The League has several courses targeted directly at aiding city cyclists and commuters. The basic course is "Traffic Skills 101," typically a 9-hour course taught in two or three sessions. After TS101 (where you learn the rules of the road and how to avoid most kinds of crashes), the "Commuting" class specifically addresses using your bike for riding to work and back as well as for errands, how to carry and pack stuff on the bike, and selecting a safe route to ride. Because of daylight savings time and shift work, "Commuting" also covers riding at night, and riding in bad weather in some detail. When we do that course, there's an optional night ride to get familiar with low light conditions as well as bike lights and reflective gear.

Here's some good video, which I use in TS101:
