IC Bus - A History of Innovation

For over 90 years, IC Bus has been moving students safely to and from school. What started as a small operation in Arkansas has become one of the most recognized names in school transportation—a brand known for building buses that last, equipped with advanced safety features, and designed to make the driver’s job easier.

The Many Stops Along the Way

International Harvester (the predecessor to today’s company) started building commercial and school buses in 1915. IC Bus, known then as Ward Body Works, was founded in 1933 in Conway, Arkansas. The company—and later AmTran—earned a reputation for building tough, reliable school buses with safety baked in.

In 1991, Navistar International bought into the company, and by 1995 owned it completely. A few years later, they opened an assembly plant in Tulsa, Oklahoma. The facility started production in 2001 with a simple approach: build everything in one place, get it right, and keep everyone safe. More than 250,000 buses have come out of that plant since then.

In 2023, IC Bus rolled out the Next Generation CE Series—a significant redesign that brought real upgrades in safety, comfort, and tech.

Safety First. Last. And Always.

Safety has always mattered at IC Bus, but it's gotten smarter over time. When electronics became standard in vehicles, IC Bus added Electronic Stability Control to help drivers stay in control when roads get slick or turns come up fast. It was an early move toward active safety that cut down on rollovers and loss-of-control crashes.

Next came systems that watch the road ahead. Collision Avoidance Systems monitor traffic and help drivers avoid or reduce front-end crashes. Bendix Wingman technology brought adaptive cruise control and active braking.

Visibility around the loading zone was also addressed. IC Bus redesigned the hood on newer buses to give drivers another 11 inches of forward view, making it easier to see kids in front of the bus and cutting down on blind spots.

Being visible is just as important. IC Bus features illuminated safety features to help make buses stand out in fog, rain, or darkness. In fact, First Light Illuminated School Bus Signs (ISBS) and Fully Illuminated Stop Arms (FISA) are now standard on IC Bus™ Electric CE Series and CE Series School Buses. These important features make it clear to other vehicles on the road when a bus is stopped and loading.

A Pleasant Ride to School

IC Bus pays attention to the driver's workspace because small things add up. As part of our Driver First philosophy, we want to ensure the driver is comfortable and has all the tools they need to safely transport children to and from school. For example, the instrument panel is angled toward the driver for easy reach. Digital displays keep information clear. Better HVAC keeps the cab comfortable year-round. Storage compartments and cup holders are large and easily accessible, and several driver’s seats are available, including air-ride suspension seating. All driver’s seats are adjustable for height, tilt and fore/aft.

Advanced Remote Diagnostics from IC Bus helps keep buses running and cuts operating costs, letting schools manage different buses without juggling multiple platforms. The system can alert both drivers and fleet managers of issues that need attention. This preventative maintenance can stop small issues from becoming larger ones.

In addition to vehicle health, Advanced Remote Diagnostics tracks driver performance, including harsh braking, rapid acceleration, and excessive speed. This insight helps schools support safer driving habits, improve training, and reinforce accountability.

A Lesson in Efficiency

Launched in 2023, the IC Bus Electric CE Series brings an electrified take on the brand's flagship CE model. It delivers smooth, consistent acceleration and reliable power, while supporting districts with sustainability goals. And with fewer moving parts and reduced brake wear, it can help lower maintenance demands over time. It's a vision that extends beyond the product itself. "We continue to believe that the school bus is a prime early application for vehicle electrification," said Mathias Carlbaum, CEO and president. "The introduction of the next generation of IC Bus allows us to build solutions today that transport the next generation to a better, more sustainable future."

Making the switch to electric is made easier through a specialized Zero Emissions team that guides customers through three core phases: consultation, charging setup, and deployment. Leveraging a robust network of partnerships and IC Bus® dealers, the team supports customers at every stage, from identifying the right charging solutions to running route planning simulations and optimizing operations for real-world performance.

Making the Honor Roll

More than 1,600 dedicated team members build approximately 11,000 new buses annually at "The Tulsa Mile," where the chassis, engine, body, and options are all assembled inside the emerald-hued, mile-long assembly floor. With an average tenure of 6.5 years, these skilled workers provide more than $60 million in direct income to the Tulsa community each year, making IC Bus not just a manufacturer but a vital economic anchor for the region.

IC Bus mixes decades of experience with practical innovation. Smarter safety systems, better visibility, tougher construction, improved comfort, and fleet management tools all serve one goal: protect students, support drivers, and help schools do their jobs better. It's a brand built on history but focused on what's next—safer, smarter, more reliable transportation for the road ahead.
