To help reduce your risk of a serious biking injury, the United States National SafetyCouncil recommends the following: obey traffic laws; understand the limits of your bike; bike in a single-file line in the same direction as traffic; watch for dangers such as open car doors; use hand signals when you turn; look left, right, left again, and over your shoulder before biking into traffic; ride only during daylight hours; wear bright clothing; if you must ride at night, make sure your clothing is reflective and your bike has reflectors on the spokes, front, rear, and pedals; and equip your bike with a bright headlight, a rear-view mirror, and a horn. —National Safety Council, July 2017
