An Act

to amend

relating to:

lighting on police vehicles.
Analysis by the Legislative Reference Bureau
Current law provides that a police vehicle may be equipped with flashing, oscillating, or rotating blue and red lights. On a marked police vehicle, the blue light must be mounted on the passenger side of the vehicle and the red light must be mounted on the driver side of the vehicle.
This bill provides that, on a marked police vehicle with an exterior light bar, the blue light must be mounted on the roof of the passenger side of the vehicle and the red light must be mounted on the roof of the driver side of the vehicle. For lights mounted inside the vehicle, blue lights must be displayed on the interior of the passenger side of the vehicle and red lights must be displayed on the interior of the driver side of the vehicle. The bill also authorizes the use of a combination of blue and red lights mounted on the front, sides, or rear of a police vehicle if the vehicle is already equipped with roof or interior lights as required by the bill.
The people of the state of Wisconsin, represented in senate and assembly, do enact as follows:
SB159,1

Section

.
347.25 (1m) (b) of the statutes is amended to read:
SB159,2,21
1
347.25
(1m)
(b) If the vehicle is so equipped, the lights shall be illuminated as
2
required under s. 346.03 or 346.215 (2) (a) when the operator of the police vehicle is
3
exercising the privileges granted under s. 346.03 or 346.215 (2) (a). On a marked
4
police vehicle
with an exterior light bar
, the blue light shall be mounted on the
roof
5
of the
passenger side of the vehicle and the red light shall be mounted on the
roof of
6
the
driver side of the vehicle.
If lights are mounted inside the vehicle, blue lights
7
shall be displayed on the interior of the passenger side of the vehicle and red lights
8
shall be displayed on the interior of the driver side of the vehicle. On marked police
9
vehicles with blue lights displayed on the passenger side roof or interior and red
10
lights displayed on the driver side roof or interior, a combination of additional blue
11
and red lights may be mounted on the front, sides, or rear of a police vehicle in any
12
configuration.
When in use on an unmarked police vehicle, the blue light shall be
13
displayed on the passenger side of the vehicle and the red light shall be displayed on
14
the driver side of the vehicle. The lights shall be designed and displayed so as to be
15
plainly visible and understandable from a distance of 500 feet during normal
16
sunlight and during hours of darkness. No operator of a police vehicle may use the
17
warning lights except when responding to an emergency call or when in pursuit of
18
an actual or suspected violator of the law, when responding to but not upon
19
returning from a fire alarm, when necessarily parked on a highway in a position
20
which is likely to be hazardous to traffic using the highway, or as authorized under
21
s. 346.215 (2) (a).
