Bike helmets should sit evenly between the ears and low on the forehead. See and be seen. Ride so cars can see you. Wear bright colors or clothes that reflect light at night so cars, buses, and trucks can see you. Follow the rules.
Bikes have to follow the same traffic rules and signs as cars.
You must ride in the same direction as the cars are going. Ride your bike single-file. Signal when you want to stop or turn. Look out for holes, wet leaves, or cracks in the street. They can make you crash your bike.
