School in Sacramento is back in session, which means students and drivers alike are being reminded of safety rules.
"Walk towards traffic, not against it, so you see traffic coming," Sacramento Police Officer Justin Brown said.
Mark Black, of Sacramento, said defensive driving in school zones is important.
Pedestrians, cyclists or other cars can seemingly come out of nowhere.
"Just use common sense and obey the rules of the road," Brown said.
According to the Safe Routes to School National Partnership, 250 kids were killed by cars while walking or biking to school in 2009.
"Make sure they're not distracted," Brown said. "Make sure they're not texting while they're walking, having earphones in their ears."
Classes in the Sacramento City Unified School District started Tuesday.
