You should always wear a bike helmet when on your bike. A properly fitted bike helmet protects you from serious head injury in a collision.
You should follow the rules of the road. This means riding your bike on the right side of the road, and obeying traffic signs and signals. By ordinannce your bike is required to have a headlamp and red tail lamp lit during hours of darkness. You also need to have proper reflectors on the bike. You may be able to see fine, but you want motorists to be able to see you from a distance.
Children can learn more about bike safety by attending the annual bike safety rodeo sponsored by the Safe Community Coalition and the Sauk Prairie Police Dept. The date and time of the event is usually sent home in a school bullitin and posted in the local newspapers.
