Normal bicycle safety guides usually tell you to wear you helmet(头盔) and to obey the law in order to avoid being hit on a bike. Is this advice really helpful?

Consider this for a moment: Wearing a helmet will absolutely do nothing to prevent you from getting hit by a car. Surely, a helmet might help you if you get hit, but you No.1 goal should be to avoid getting hit. Plenty of cyclists were killed by cars__________. However, if they had ridden without helmets, yet followed the guidelines listed below, they might still be alive today. So they saying that wearing a helmet is the first and last word in bike safety is, to some degree(在一定程度上), wrong.

The most common bike safety advice is “follow the law”. Ridiculously, most people are already aware that it’s stupid to race through a red light at a crossroads. As a result, it’s clear that the “follow the law” advice isn’t that helpful, either. In addition, following the law is not enough to keep you safe. Here’s an example: The law tells you to ride on the right, but if you ride too far to the right, someone started a parked car could open their door right in front of you and motorists pulling out of driveways and parking lots will be less visible. In that case you were following the law, but could still have been hit.

Then what should we remember in order to keep safe when riding a bike? I will tell you about it in the following paragraph.
