Luis Lopez, Bakersfield City School District takes 2 nd Place in Transit Category at the School Bus Driver International Safety Competition in Austin, Texas

Drivers from 26 states competed at the 50 th Edition of the School Bus Driver International Safety Competition in Austin, Texas this past weekend and California’s very own, Luis Lopez from Bakersfield City School District won 2 nd Place.

Luis was crowned the CASTO California State Roadeo Champion on Memorial Day Weekend and with that win qualified to compete against the countries best school bus drivers.

“Wow, this year has been an absolute dream, competing for the State of California and representing my school district, Bakersfield City!” said Luis.

“This experience has been incredible. So many great drivers from all over the country and even the best from Canada. We gave it our best and it was not easy, but California took 2nd place this year. But (we) will work twice as hard next year to make sure we bring home the 1st place title in 2025.”

“I would also like to encourage all of our California drivers to compete and keep growing our CASTO Family so we can put our best drivers against everyone else in the Nation. Lastly, I would like to thank Doug Smith and Antonio Perez and all the CASTO staff and all the volunteer judges, nothing would be possible without any of them. California rocks!”

Luis would also like to thank his Bakersfield City family and everyone in Chapter 12 for supporting him.

On behalf of CASTO, Congratulations Luis on a job well done! We are all proud of you.

Presidents Message

Presidents Message: Summer 2024

As we reach the end of another school year, I want to extend my heartfelt gratitude to each and every one of you. Your dedication, professionalism, and unwavering commitment to safely transporting our students have been truly exceptional. This year, like every year, you have gone above and beyond to ensure that our children have reliable and safe access to their education, and for that, we are immensely grateful.

As summer break approaches, I encourage you to take this well-deserved time to rest and rejuvenate. The work we do is demanding and often comes with challenges that require our utmost attention and energy. It’s crucial that we use this period to recharge our batteries, spend quality time with our loved ones, and engage in activities that bring us joy and relaxation.

Whether you are planning a vacation, enjoying a staycation, or simply taking a few quiet moments for yourself, I hope you find the peace and relaxation you deserve. Remember, taking care of ourselves is just as important as taking care of our responsibilities.

As we look forward to the upcoming school year, let’s carry the spirit of rest and renewal with us. A refreshed and revitalized team is key to continuing our mission of providing safe and efficient transportation for all students.

Thank you once again for your incredible work and dedication. Have a wonderful, restful, and enjoyable summer break!

Warmest regards,

Mike Sawyer | President

Chapter Highlights

CASTO Chapter 1 “Where it All Began” 2024 Report

On January 27th, Chapter 1 successfully marked its transition from Zoom to an in-person Driver Safety Workshop since Covid. This significant shift was met with enthusiasm, as evidenced by the impressive turnout of 160 attendees. We streamlined our workshop schedule to 4 presenters, a change that was well-received by all, including the presenters. The day was about learning, fun, and camaraderie, with everyone participating in the Chapter 1 hosted giveaways that included a 55” TV, vendor-donated items, and gift cards.

Our next event was the Roadeo workshop, which was held on February 17th at the Redlands USD Transportation Center and presented by Doug Smith and Antonio Perez. The topic’s presented were, Preparing for a Roadeo, Off Set Alley, Student Loading with an escort and Parallel Parking. A pizza lunch was provided, along with several giveaway prizes. The 40 drivers in attendance gained a lot of Roadeo information along with several pointers to help them navigate the events. Several of the workshop attendees participated in the local Roadeo’s and at the Southern Sectional and are already planning for next year.

The last event of the year was the annual Roadeo on March 23RD at the San Bernardino County Sheriff’s Rodeo grounds at the Glen Helen Regional Park in Devore. We had a good turnout of about 40 drivers and plenty of event judges. This year’s Roadeo had an additional challenge added shortly after the first bus went on the course; a light, steady rain helped keep the temperature down but did not dampen the enthusiasm of the drivers or the judges. Bus West provided a taco lunch, and the “Burrito Lady” was there in the morning, serving hot coffee and burritos. The in-chapter winners were Leslie Baker, 1st place & Jessica Cole, 3rd place, from Lake Elsinore USD; Sergio Duenas, 2nd place & Jose Reyes, 4th place, from First Student in San Bernardino. The out-of-chapter winners were Rosa Rosas, 1st place; Kim Dailey, 2nd place; and Tim Tran, 3rd place, all from Garden Grove USD.
