1. Keep yourself visible.
Make sure that other riders and motorists are aware of your presence on the road. Always signal your intentions. Signal before you turn, so that as you are actually turning, you can keep both hands on your handlebars.
2. Make sure your movements are predictable.
Adhere to traffic laws and rules of the road. Don't dart in and out of traffic, or make sudden stops or turns.
3. Negotiate with other vehicles.
Work with automobiles and other vehicles, not against them. If you're cycling slowly, wave a faster-moving vehicle around you. Even though you have the right-of-way, you may want to let a car turn or go before you at times. Motorists will appreciate the nod, and behavior like this certainly helps warm motorists' attitudes towards cyclists in general.
