A new law requiring a certain amount of space between a vehicle and a bicycle will come into effect Sept. 16.
A driver must allow 3 feet of space when passing or overtaking a bicyclist, according to the California Highway Patrol. In cases when there's not enough space, the driver must slow down and pass when there's no danger present.
"Motorists are reminded to pay close attention as the school year approaches and exercise caution when they see bicyclists on the road," according to a statement from CHP Commissioner Joe Farrow.
There will be more children riding their bikes with school starting again, according to CHP.
