3EXPLANATION
4The inclusion of this explanation does not constitute agreement with
5the explanation’s substance by the members of the general assembly.
   6In 2015, the general assembly authorized motor trucks,
7trailers, tractors, truck-mounted snow blowers, and motor
8graders owned by the department of transportation and used for
9snow and ice treatment or removal to display rear-facing blue
10and white lighting devices or reflectors in conjunction with
11amber lighting devices or reflectors. These authorizations
12were set to be repealed July 1, 2019. In 2018, the general
13assembly struck these future repeal provisions.
   14This bill applies those authorizations to such vehicles
15owned by the state or any political subdivision of the
16state, including any local authority. Under Code chapter
17321, a “local authority” is any county, municipal, and other
18local board or body having authority to adopt local police
19regulations under the constitution and laws of the state.
   20The bill allows authorized emergency vehicles to be equipped
21with a variety of lighting devices, including flashing
22headlamps, flashing or solid white lights, split red and blue
23steady or flashing lights, and lights or light bars containing
24one or more rear zone amber lights or amber directional arrows.
25The bill requires authorized emergency vehicles to be equipped
26with a combination of operational red and blue lights, and
27if equipped with a light bar, requires the light bar to be
28positioned such that the front and rear facing red lights are
29on the driver’s side of the vehicle and the front and rear
30facing blue lights are on the passenger’s side of the vehicle.
31In addition, an incident command vehicle may be equipped
32with one or more steady or flashing green lights. However,
33a towing or recovery vehicle, unless owned by the state or a
34municipality, is prohibited from being equipped with red and
35blue lights and a siren.
