What laws do bicyclists have to follow?

The signs say "share the road" with bicyclists. Before you zoom past a bicyclist, there are a few rules you should know.

Officer Marcus Trujillo with the San Antonio Police Department has these tips:

"Not only to bicyclists have to obey the same traffic laws that the vehicles do, but also because of the safe passage ordinance when vehicles are passing bicycles that are on the roadway , they have to make sure that they keep the minimum distance. If it's a passenger vehicle, light truck, there's a minimum of six feet clearance that they have to give the bicycle when they pass the bicycle and they can only pass the bicycle when it's safe to do so. Also when it's commercial traffic trying to pass a bicycle, that minimum distance increases to 10 feet.  

Bicyclists at night also have to be seen just like everybody else especially since they are in the roadway and they shouldn't be in the sidewalk so therefore you have to have the rear light in the back and the headlight in the front so that you'll be seen properly. It's a good idea to have as much reflective gear on you as possible."
