Make Every Mile Safe for Students
Imagine starting your shift in a modern shop, reviewing diagnostics on a route-critical school bus, and tracing a performance issue back to an electrical connector you spotted on a hunch. You button up the repair, take a test drive to verify the fix, document your work, and return a safe, reliable vehicle to the yard—ready for students’ morning pickup. That’s a typical win at Zūm.
