Senate Bill 273 proposes an amendment to Wisconsin law regarding the equipment requirements for commercial motor vehicles (CMVs). Currently, the law mandates that all motor vehicles must be equipped with mirrors to provide a rear view of the roadway. However, the Federal Motor Carrier Safety Administration (FMCSA) has established an exemption for CMVs that utilize a specific camera monitor system instead of traditional mirrors.

The bill introduces a new section, 347.40 (4), which allows CMVs to be equipped with an FMCSA-approved camera monitor system as a substitute for mirrors. This change aims to modernize vehicle safety requirements and align state regulations with federal exemptions, thereby providing more flexibility for commercial vehicle operators while maintaining safety standards.
