AB271,1,2
1
An Act

to create
347.40 (4) of the statutes;
relating to:
camera monitor
2
systems as an alternative to mirrors for commercial motor vehicles.
Analysis by the Legislative Reference Bureau
Current law prohibits any person from operating a motor vehicle on a highway unless the vehicle is equipped with a mirror to provide a view of the roadway to the rear of the vehicle. Current regulations of the Federal Motor Carrier Safety Administration (FMCSA) require commercial motor vehicles (CMVs) to be equipped with mirrors on each side of vehicle positioned to provide a view of the highway to the rear and along both sides of the CMV. FMCSA has created an exemption to this requirement for CMVs equipped with a specified camera monitor system.
This bill provides that a CMV may be equipped with a camera monitor system approved by FMCSA as an alternative to mirrors that would otherwise be required.
The people of the state of Wisconsin, represented in senate and assembly, do enact as follows:
AB271,1
3
Section

1
.
347.40 (4) of the statutes is created to read:
AB271,2,2

347.40
(4)
Notwithstanding sub. (1) and
49 CFR 393.80 (a)
, a commercial

motor vehicle may be equipped with a camera monitor system approved by the

federal motor carrier safety administration as an alternative to mirrors.
