The Davis School District is trying to conserve every drop of fuel it can.
Soaring fuel prices have hit the district hard in the budget, so Davis officials are looking at ways to make the bus system more efficient.
The district has adjusted some routes to consolidate driving time and fuel. They say the big yellow buses get about 5 to 7 miles to the gallon.
District officials also want drivers to fill up buses and maintenance vehicles at a specific station, which has a designated state fuel site and a cheaper rate for the vehicles.
Meanwhile, some route adjustments are forcing some students to walk out of their subdivisions to catch the bus on a busy highway.
"I'd say it's a safety issue anytime you have a child on the street, you know, for a longer stretch getting to school. There could be a hazard there for some of the kids," said district spokeswoman Chris Williams.
The subdivisions these route changes will affect have yet to be determined.
