2 49-948. RESTRICTIONS AS TO TIRE EQUIPMENT. (1) Every solid rubber tire on
3 a vehicle shall have rubber on its entire traction surface at least one (1)
4 inch thick above the edge of the flange of the entire periphery.
5 (2) No person shall operate or move on any highway any motor vehicle,
6 trailer, or semitrailer having any metal tire in contact with the highway.
7 (3) No tire on a vehicle moved on a highway shall have on its periphery
8 any block, stud, flange, cleat, spike, or any other protuberance of any mate-
9 rial other than rubber which projects beyond the tread of the traction surface
10 of the tire, except as allowed herein. It shall be permissible to use farm
11 machinery with tires having protuberances which will not injure the highway,
12 and it shall be permissible to use tire chains. Tires with built-in lugs of
13 tungsten carbide or other suitable material, hereinafter called studs, may be
14 used upon any vehicle when required for safety because of snow, ice, or other
15 conditions tending to cause a vehicle to skid, that will not unduly damage the
16 highway. Motor vehicles, trailers and semitrailers with tires having built-in
17 studs are prohibited on public highways between the dates of May 1 and Septem-
18 ber 30, annually, except as provided in paragraphs (a) and (b) of this subsec-
20 (a) Fire pumper/tanker trucks and ladder trucks belonging to fire depart-
21 ments and firefighting agencies are exempt from the prohibited dates.
22 (b) Special exemptions from the prohibited dates may be granted by the
23 Idaho transportation board if it is found by the board that enhancements
24 to public safety outweigh the increased pavement wear.
25 (4) Commercial tire retailers shall not sell studded tires with studs
26 exceeding the following weight and protrusion limitations after July 1, 2005.
27 Commercial tire retailers and tire shops shall not manually install studs
28 exceeding the following weight and protrusion limitations after July 1, 2005.
29 (a) Studs shall not protrude more than six-hundredths (.06) of an inch
30 from the surface of the tire tread when originally installed.
31 (b) Stud size shall be as recommended by the manufacturer of the tire for
32 the type and size of the tire.
33 (c) Studs shall individually weigh no more than one and one-half (1.5)
34 grams if the stud is size 14 or less.
35 (d) Studs shall individually weigh no more than two and three-tenths
36 (2.3) grams if the stud size is 15 or 16.
37 (e) Studs shall individually weigh no more than three (3) grams if the
38 stud size is 17 or larger.
39 (5) If the transportation department determines at any time for any part
40 of the interstate highway system or other highways of the state highway system
41 that the unsafe conditions of the roadway require particular tires, tire
42 chains or traction equipment in addition to or beyond the ordinary pneumatic
43 rubber tires, the department may establish the following requirements for the
44 use of traction equipment on all vehicles traveling upon the interstate high-
45 way system or other highways of the state highway system:
46 (a) Traction advisory "A" -- Chains required on commercial vehicles as
47 defined in section 49-123, Idaho Code. This requirement shall be met by
48 chaining a minimum of one (1) tire on each side of:
49 (i) One (1) drive axle regardless of the number of drive axles; and
50 (ii) One (1) fixed axle at or near the rear of each towed vehicle.
51 Such fixed axle shall not include a variable load suspension axle or
52 an axle of a converter dolly.
53 (b) Traction advisory "B" -- Chains required on all vehicles except all-
54 wheel drive vehicles.
1 (6) Chains as required in subsections (5)(a) and (5)(b) of this section
2 mean metal traction devices as defined in section 49-104, Idaho Code. Any
3 other traction devices differing from such metal chains in construction, mate-
4 rial or design but capable of providing traction equal to or exceeding that of
5 such metal chains under similar conditions may be used.
6 (7) The department shall place and maintain signs and other traffic con-
7 trol devices on the interstate and state highways that indicate the tire, tire
8 chain or traction equipment requirement as determined by the department. Such
9 signs or traffic control devices shall in no event prohibit the use of studded
10 tires from October 1 through April 30, but when the department determines that
11 chains or other acceptable traction devices are required and that no other
12 traction equipment will suffice, the requirement is applicable to all types of
13 tires including studded tires. The department may specify different require-
14 ments for all-wheel drive vehicles when in gear.
15 (8) Authorized emergency vehicles as defined in section 49-123, Idaho
16 Code, and those operated by the transportation department when used in the
17 maintenance of the interstate or state highway system are exempt from the pro-
18 visions of subsection (5) of this section.
STATEMENT OF PURPOSE
Amends Sections 49-104, 49-123 and 49-948, Idaho Code, to require
tire chains on sections of highway that have been posted by the
transportation department as requiring those devices due to
hazardous driving conditions.
