    Riding on the road? Time to review all that you learned in elementary school —especially if you'll be riding in traffic.

Always ride on the right side of the street in the same direction as the traffic. Never ride against traffic. Try to use bike lanes (车道)whenever you can.

Always stop and check for traffic in both directions when leaving your driveway. Some people in cars just don't see cyclists.

Watch traffic closely for turning cars or cars pulling out of driveways.

Don' t ride too closely to parked cars — doors can open suddenly!

Stop at all stop signs and stop at red lights just as cars do. Take special care at crossroads. It's d good idea to walk your bike across busy crossroads using the crosswalk.

Don't wear headphones while biking—you need to hear what's going on around you.

Never change directions or change lanes without first looking behind you and using the correct hand signals. That way everyone knows where you' re going. You can use your left arm for all hand signals. To show you' re making a left turn, hold your arm straight out to the left. To show a right turn, bend your elbow(肘部)，holding your arm up in an “L” shape. And before you stop, bend your elbow, pointing your arm downward in an upside down “L” shape. Of course, you can also hold your right arm straight out to the right to show you are going to turn right.
