Plain-language change summary

The recent amendment to Assembly Bill 271 allows commercial motor vehicles (CMVs) in Wisconsin to use camera monitor systems instead of traditional side mirrors, in line with a federal exemption. This change means that as long as the camera system is approved by federal safety regulations, drivers can have a clearer view without bulky mirrors. This amendment matters because it could enhance safety by reducing blind spots and may provide drivers with more streamlined vehicle designs.
