A careless driver could be opening a door in your path. Obey Traffic Laws Bicycles are considered vehicles. Bicyclists must obey the same rules as motorists. Always signal your moves. Be courteous to pedestrians and other vehicle operators.
Pedestrians get to go first.
Yield the right of way, and keep a sharp lookout for danger in every direction if you have to adjust your path. Never wear headphones while riding as they impair your ability to hear traffic. Become familiar with the accommodations that are available for bicyclists in your area. These include bicycle lanes and routes as well as off road paths. Take advantage of these whenever possible.
