26 EXPLANATION
27 The inclusion of this explanation does not constitute agreement with
28 the explanation’s substance by the members of the general assembly.
29 In 2015, the general assembly authorized motor trucks,
30 trailers, tractors, truck-mounted snow blowers, and motor
31 graders owned by the department of transportation (DOT)
32 and used for snow and ice treatment or removal to display
33 rear-facing blue and white lighting devices or reflectors in
34 conjunction with amber lighting devices or reflectors. These
35 authorizations were set to be repealed July 1, 2019. In 2018,
LSB 2272HV (2) 89
-5- th/ns 5/7
H.F. 654
1 the general assembly struck these future repeal provisions.
2 This bill applies those authorizations to such vehicles
3 owned by the state or any political subdivision of the
4 state, including any local authority. Under Code chapter
5 321, a “local authority” is any county, municipal, and other
6 local board or body having authority to adopt local police
7 regulations under the constitution and laws of the state.
8 The bill allows authorized emergency vehicles to be equipped
9 with a variety of lighting devices, including flashing
10 headlamps, flashing or solid white lights, split red and blue
11 steady or flashing lights, and lights or light bars containing
12 one or more rear zone amber lights or amber directional arrows.
13 The bill includes as vehicles authorized to use a flashing
14 white light motor trucks or trailers owned and operated by the
15 DOT equipped with an impact attenuator and audible warning
16 system, if the flashing white light is rear-facing on the
17 audible warning system and used in conjunction with amber
18 lighting devices or reflectors while the motor truck or trailer
19 is being used for slow-moving maintenance operations, and
20 vehicles or other equipment not owned and operated by the DOT
21 when used in road work zones on state or local highways as
22 authorized by the DOT.
23 The bill requires authorized emergency vehicles to be
24 equipped with a combination of operational red and blue lights,
25 and if equipped with a light bar, requires the light bar to
26 be positioned such that the front and rear facing red lights
27 are on the driver’s side of the vehicle and the front and rear
28 facing blue lights are on the passenger’s side of the vehicle.
29 The bill also requires an official fire department or emergency
30 medical services vehicle purchased, delivered, or refurbished
31 on or after July 1, 2021, to be equipped with a master warning
32 switch to activate all emergency lights on the vehicle, in
33 addition to one or more switches to separately activate or
34 isolate the front, side, and rear warning lights. In addition,
35 an incident command vehicle may be equipped with one or more
LSB 2272HV (2) 89

H.F. 654
1 steady or flashing green lights. A towing or recovery vehicle
2 may be equipped with red and blue lights. However, unless
3 owned by the state or a municipality, a towing or recovery
4 vehicle is prohibited from being equipped with a siren.
5 Under current law, a violation of Code section 321.423 or
6 321.433 is punishable by a scheduled fine of $45. The bill
7 provides that violations of Code section 321.424 are also
8 punishable by a scheduled fine of $45.
9 The bill takes effect upon enactment.
