EXPLANATION

6

The

inclusion

of

this

explanation

does

not

constitute

agreement

with

7

the

explanation’s

substance

by

the

members

of

the

general

assembly.

8

This

bill

relates

to

vehicles

operating

with

a

permit

for

9

excessive

size

or

weight

(permit).

10

Permits

are

generally

issued

by

the

authority

responsible

11

for

the

maintenance

of

the

system

of

highways

or

streets

on

12

which

the

permitted

vehicles

are

authorized

to

travel.

One

13

such

permit

is

an

all-systems

permit

that

may

be

issued

by

14

the

department

of

transportation

(DOT)

to

authorize

movement

15

on

most

paved

highways

or

streets,

excluding

the

interstate

16

road

system

and

any

highway

or

street

under

local

authority

17

where

the

permit

is

not

valid,

as

determined

by

the

local

18

authority,

if

indicated

to

the

DOT.

Despite

local

authority

19

determinations,

permitted

vehicles

may

still

travel

the

20

shortest

route

between

loading

and

unloading

sites

and

valid

21

highways.

The

bill

makes

an

all-systems

permit

valid

for

22

movement

on

all

primary

and

secondary

roads,

including

roads

23

designated

by

a

local

authority

as

a

truck

route,

subject

24

to

the

exceptions

for

the

interstate

road

system

and

roads

25

deemed

not

valid

by

a

local

authority.

Under

the

bill,

a

road

26

designated

as

not

valid

is

subject

to

DOT

review.

If

the

DOT

27

disagrees

with

the

justification,

the

dispute

must

be

resolved

28

in

accordance

with

DOT

rules.

The

bill

requires

a

local

29

authority

to

cooperate

with

the

DOT

to

find

alternate

routes

if

30

all

roads

leading

to

a

loading

and

unloading

location

used

by

a

31

permitted

vehicle

are

designated

as

not

valid.

32

Current

law

authorizes

the

DOT

to

issue

an

all-systems

33

permit

valid

for

the

movement

of

vehicles

with

a

total

gross

34

weight

not

to

exceed

the

gross

weight

authorized

under

Code

(maximum

gross

weight),

which

varies

based

on

1

the

number

of

axles

and

distance

between

the

axles,

by

more

2

than

12

percent.

The

bill

increases

the

allowable

weight

3

variance

for

such

permitted

vehicles

to

not

more

than

12.5

4

percent.

5

Under

current

law,

containers

for

international

shipment

6

must

be

considered

an

indivisible

load

when

transported

under

a

7

single-trip

permit

if

the

vehicle

combination

does

not

exceed

8

maximum

dimensions,

the

container

is

sealed

for

international

9

shipment

and

is

either

being

exported

or

arriving

from

a

10

foreign

country,

specified

documentation

is

carried

in

the

11

vehicle,

and

the

container

holds

only

raw

forest

products.

The

12

bill

strikes

the

requirement

that

the

container

hold

only

raw

13

forest

products.

14

Under

current

law,

the

DOT

and

local

authorities

are

15

authorized

to

issue

single-trip

permits

for

the

movement

of

16

vehicles

that

exceed

established

dimensions

and

weight

limits

17

(Code

section

321E.9).

A

vehicle

traveling

under

an

oversize

18

or

overweight

permit

is

required

to

be

registered

for

the

gross

19

weight

of

the

vehicle

and

load.

The

owner

of

a

commercial

20

vehicle,

which

is

properly

registered

and

licensed

in

some

21

other

jurisdiction

and

also

operated

occasionally

in

Iowa,

22

who

pays

the

$10

trip

permit

fee

that

otherwise

authorizes

23

a

commercial

vehicle

not

registered

in

Iowa

to

be

operated

24

in

Iowa

for

up

to

72

hours,

in

accordance

with

Code

section

25

326.23,

cannot

use

that

trip

permit

in

lieu

of

the

oversize

26

or

overweight

vehicle

registration

requirements.

The

bill

27

authorizes

a

vehicle

traveling

under

a

single-trip

permit

to

be

28

registered

with

the

DOT

on

a

single-trip

basis

for

the

combined

29

gross

weight

of

the

vehicle

and

load.

The

fee

for

single-trip

30

registration

is

$4

per

ton

exceeding

40

tons.

The

bill

strikes

31

the

prohibition

on

using

a

Code

section

326.23

trip

permit

in

32

lieu

of

registration.
