The 2012 Chevrolet Express 2WT is a heavy-duty commercial cutaway chassis commonly outfitted as a short school bus, paratransit vehicle, or shuttle bus. The "2WT" designation represents the standard Work Truck trim level for the Express 4500 series chassis, which provides the high-GVWR foundation required for multi-passenger bus bodies.

Common Bus Configurations
Because the 2WT is a "cutaway" chassis, Chevrolet supplied the front cab and drivetrain, while secondary manufacturers built out the bus body. Some of the most common applications for this specific 2012 model year include:
- Type A School Buses & Daycare Shuttles: Often outfitted by coachbuilders like Thomas Built, Collins, or Trans Tech. These variants feature high-backed school bench seats with seatbelts, flashing signal lights, stop arms, and a "Child Check Mate" safety alarm system.
- Paratransit & ADA Shuttle Bases: Upfitted by companies like ElDorado National or StarTrans. These configurations typically accommodate 10 to 14 passengers and include a hydraulic wheelchair lift, dedicated wheelchair tie-down tracks, and an electric entry door.
