SB 273 Wisconsin Senate · 2025-2026 Regular Session

Relating to: camera monitor systems as an alternative to mirrors for commercial motor vehicles.

SB 273 allows commercial motor vehicles to use federally approved camera monitor systems instead of traditional mirrors, as permitted under federal regulations. The bill directly affects commercial trucking operators and drivers by providing an alternative to standard mirror requirements (49 CFR 393.80(a)). It requires camera systems to be exempted by the Federal Motor Carrier Safety Administration or approved under federal safety standards. This change modifies state law to align with federal approval processes for such technology.
