4 . More people are increasingly biking to commute (上下班往返), for exercise, or just for fun. Bicyclists should observe bicycle safety rules to help reduce deaths and injuries on the road.

Wear a helmets

Avoid crashes

There are two main types of crashes: the most common (falls) , and the most serious (the ones with cars). Regardless of the reasons for the crash, prevention is the key point.

Be alert (警惕的)

Be alert to the road and all traffic around you; anticipate what others may do before they do it. This is defensive driving — the quicker you notice a potential conflict, the quicker you can act to avoid a potential crash.

Pay attention to road signs and road conditions

Obey street signs, signals, and road markings, just like a car. Look ahead for risks or situations to avoid what may cause you to fall, like potholes (坑洼) and train tracks. No texting, listening to music or using anything that distracts you by taking your eyes and ears or your mind off the road and traffic.

Ride in the same direction as traffic

This way, if the sidewalk ends, you are already riding with the flow of traffic. If crossing a street, motorists will look left, right, left for traffic. When you are to the driver’s left, the driver is more likely to see you. Slow and look for traffic (left — right — left and behind) when crossing a street from a sidewalk; be prepared to stop and follow the pedestrian signals.
