Page 10: Rules For Safe Riding
RULES FOR SAFE RIDING Know and observe local bicycle riding laws Most state and local areas have specific laws for cyclists, and you should follow them. Local cycling clubs or your state’s Department of Transportation (or equivalent) should be able to supply this information to you. The requirements for items such as lights and reflectors change between areas, so check ahead. - Page 11 and longer stopping distances in wet weather. Anticipate the extra distance it will take to stop. Wet weather causes reduced traction. Use slower cornering when traction is reduced, such as when riding over wet leaves, painted crosswalks, or manhole covers. When wet weather cools to below freezing, traction is reduced even further.
- Page 12 Avoid riding too fast Higher speeds create higher risks and greater forces in the event of a crash. At higher speeds, it is more likely that wheels will slip, or that a small bump can create a significant impact to your frame or fork. Keep your bicycle under control at all times. For children, the limit of speed for safe riding is much lower, so parents should strictly enforce this rule.
