A Message from Rebecca Patton

The primary goal of the Transportation Department at Greenfield Union School District is to provide the safest, most efficient and professional transportation service to our students and staff and our drivers strive to meet this goal.

Before a person can apply for a special driver certificate (school bus license) to drive a school bus, he or she is fingerprinted and must submit to a thorough background investigation conducted by the California Highway Patrol. The applicant may begin training before the background check is complete, however, he/she may not take any test administered by the CHP until after the interview and background is complete and the applicant is cleared.

California’s school bus drivers receive more training than the majority of other bus drivers in the nation. Applicants for a special driver certificate must successfully complete a minimum of 20 hours of classroom instruction (covering Federal Regulations, California Vehicle Codes, California Code of Regulations and California Education Codes). They must also successfully complete a minimum of 20 hours of behind-the-wheel training to become completely competent and proficient in driving a school bus, as well as daily pre-trip inspection procedures of the bus. Applicants may not transport students until all training is complete and the applicant has successfully completed written and behind-the-wheel tests administered by the California Highway Patrol. Each year certified school bus drivers must receive at least ten hours of any type of training that is directly related to pupil transportation safety, and in the renewal year (every five years) the driver must successfully complete at least ten hours of classroom instruction (in addition to any other training received during the year).

Greenfield Union School District operates 17 buses on daily routes. Five provide curb-to-curb transportation service for special education students. Our buses travel over 180,000 miles annually and transport an average of 1,400 students daily. In addition to the regular morning and afternoon routes, the district provides transportation services for various extra-curricular activity and sports trips.

The District employs 24 certified school bus drivers with a total of over 275 combined years of school bus driving experience. Seventeen of those drivers are assigned daily routes, four are spare drivers, and three are substitute drivers.

I encourage you to browse the remainder of the Transportation Page. There is some useful information pertaining to the bus rules, explanation of the school bus red-flashing light laws, student escorting laws, procedures for bus tickets, as well as a comparison chart covering the training requirements for school bus drivers for all 50 states in the nation. You will also find the Transportation Safety Plan, bus stop information and a streets directory for the district.

Should you have any questions regarding transportation, please contact me or Julie Johnson using the contact information above.

Thank you,

-Rebecca Patton

Fog Delays

When foggy days occur leading to transportation delays, Greenfield Union School District will operate in accordance with the plans and procedures proposed by the Kern County Superintendent of Schools.  Parents should listen for announcements via the local media that refer to Greenfield Union School District, not individual schools. When transportation delays are called, school buses will run two (2) hours later than the regular time. Schools will be open at their regular time to receive students who walk or who are transported by their parents. Local radio and television stations will announce all school transportation delays. will post information regarding school delays.


When a transportation delay has been called and conditions remain severe throughout the day, all bus transportation will be cancelled.  Students who walked to school or were transported by parents will be dismissed at their regular time. Please DO NOT CALL radio or TV stations, the California Highway Patrol or the school office during morning hours for information regarding delays.  Information WILL be broadcast on local radio and TV stations. You are encouraged to not send or bring your child to school if you consider conditions unsafe.
