Do you often ride a bike to school? Here’s some advice for you.

Try not to use busy roads. In some cities there are special pains for bikes only. Use them when you can, but watch out—people often walk along them. Check the road before starting and look all around. Also, when you’re with friends on bikes, it’s much safer to ride behind, not next to, each other. Where one road meets another, you should take even more care. Slow down and check both roads. Use your eyes and be careful.

Check your bike often. Do all the parts work properly? Is there enough air in your tyres(轮胎)?

If you have an accident or fall off your bike, a helmet will protect your head. It must be the right
Size, so ask for help when you buy it.

You must use lights at night, so keep them clean and check the batteries. Don’t wear dark colours; yellow and white are the easiest colours for drivers to see.

A bike isn’t a toy and there should be only one person on it. Many children have accidents when
they play still games on their bike.

Red traffic lights aren’t only for cars and buses.They’re for you too if you’re on a bike.You’re also breaking the law if you go the wrong way up a one-way street.
