Local school districts and private schools have the responsibility for developing the specifications for and the procurement of school buses used in their pupil transportation programs and shall insure that their vehicles meet or exceed the standards contained herein. School districts are encouraged to specify requirements in excess of the standards whenever such action will enhance their transportation programs. Any additions of school bus equipment or alterations in the bus construction and operations not provided for in the Standards for Utah School Buses and Operations, 1994 Edition are prohibited without prior approval as outlined in Part H entitled "Exemption from or Modification of Requirements".

(2) Standards for Utah School Buses and Operations, 1994 Edition replaces the 1987 Standards for Utah School Buses and Operations. These standards will be effective August 31, 1994. All school buses ordered after the effective date and all school bus operators shall meet these standards. This document is intended to provide standards that meet or exceed Federal Motor Vehicle Safety Standards now in effect. Federal standards and Utah Motor Vehicle laws shall govern instances not specifically covered in these standards.

In determining passenger capacity, wheelchair positions are counted as passenger positions.

(c) The following standards address modifications as they pertain to school buses that, with standard seating arrangements prior to modification, would accommodate more than ten persons. If by addition of a power lift, wheelchair positions, or other modifications, the capacity is reduced such that vehicles become MPVs, the intent of these standards is that these vehicles are required to meet the same standards required prior to such modifications and such MPVs are included in all references to school buses and school bus requirements.

(d) School buses designed for transporting children with special transportation needs shall comply with state Standards applicable to school buses and to Federal Motor Vehicle Safety Standards (FMVSS) for their Gross Vehicle Weight Rating (GVWR) category.

R909-3-11. Exemption From or Modification of Requirements.

(1) General Requirements

(a) It is anticipated that to achieve the stated objectives of these standards, i.e., provide maximum safety consistent with the economic use of pupil transportation funds and available school bus technology, quality, reliability, conformity, and serviceability, it shall be necessary to allow exemption from the requirements and periodically modify the requirements. This part of the Standards sets forth the procedures for obtaining exemptions and modifying the provisions of the Standards for Utah School Buses and Operations, 1994 Edition.

(b) An exemption from the requirements of the Standards may be initiated by a manufacturer or supplier of pupil transportation equipment or a local school district. The request shall be written, should include sufficient supporting data to justify the request for an exemption, and should be submitted to the Pupil Transportation Specialist, Utah State Office of Education.

(c) All requests for exemptions from the requirements of the Standards shall be reviewed by a committee consisting of at least one representative of the Utah State Department of Transportation, one representative of the Utah State Department of Public Safety, and such consultants as deemed appropriate. If necessary, the committee may require that the request be presented in person.

(d) All requests for exemption from the requirements of the Standards, together with the recommendations of the review committee, shall be submitted to the State Office of Education for its action and transmittal to the Utah Department of Transportation. Final authority for determining the disposition of a request is vested with the Utah Department of Transportation.

(e) Modification Procedures.

(i) An intent to modify the Standards shall be distributed to certified suppliers and other interested parties at least thirty (30) days prior to consideration of the modification by the Utah State Office of Education and the Utah Department of Transportation.

(ii) After approval of the proposed modification by the Utah State Office of Education and the Utah Department of Transportation, the modification shall become effective 90 days following distribution.

 

R909-3-12. Appendix 1.

(1) Colorado Racking Load Test

(a) A Racking Load Test (University of Colorado, Boulder, 1972) shall be performed to assure adequate shear stiffness and strength of the bus body. The racking load shall be applied along a line connecting the most distant points on a transverse cross section of the bus interior.

(b) The maximum jack load for the two-frame assembly is determined by the following formula:

 

TABLE V

  j = 2P, where      j - maximum jack load for two-frame test

                   assembly

p = DVW - N and    p - load/frame

DVW = DF x GVW     DVW - dynamic vehicle weight

                   DF - dynamic factor, not less than 1.5

                   GVW - gross vehicle weight

                   N - total number of bus body frames



     Thus for a DF = 1.5, a GVW = 22,000 lbf and N-11, the

dynamic vehicle weight is DVW = 33,000 lbf, the 10ad/frame is

P = 3000 lbf and the maximum jack load is j = 6000lbf.

 

(c) When a complete bus body is rack loaded, the total load DVW must be distributed uniformly along the bus body. This may be accomplished by mounting a series of hydraulic jacks along the length of the bus interior. Seats may be removed to facilitate jack mounting although removal is not recommended when upper seat frames are normally attached to the body structure. The rack load will be considered to be uniformly distributed when the variation in the hydraulic jack readings is less than 10%. At maximum load the sum of all jack readings shall equal DVW.

 

R909-3-13. Appendix 2.

(1) Power Test

(a) Performance Requirements: The bus shall be so powered and geared that the completed bus shall be capable of surmounting a 3.7 percent grade at a speed of twenty miles per hour with a full passenger load on a continuous pull.

(b) Recommended Procedure:

(i) Measure the weight of the vehicle. Wt = ..... lbs.

(ii) Determine the time in seconds it takes to accelerate the bus from 15 to 25 mph on a level roadway. (T = ..... seconds).

(iii) Perform the following calculations (Where n = maximum number of passengers):

(A) Wt ₂ = Wt ......... + 300 =

(B) Wt ₂ = Wt ......... + 150 + 120n =

(C) a = 0.455/T x Wt ₁ /Wt ₂

(iv) If the "a" from step three is greater than or equal to 0.037, the bus is adequate. If it is less than .037, the bus is not adequate.

 

R909-3-14. Appendix 3.

(1) Braking Test

(a) Performance Requirement: The service braking system shall be designed and constructed such that by the application of a single control unit, the bus will achieve a deceleration of 14 feet per second from a speed of 20 mph with a pedal effort of not more than 75 pounds.

(b) Recommended Procedure:

(i) Determine the time it takes to stop the bus from 20 mph (where T = ..... seconds

(ii) If "T" is less than or equal to 2.5 seconds, the bus is adequate. If it is greater than 2.5 seconds, the bus is not adequate.

(iii) Contact Pupil Transportation Specialist, State Office of Education, for use of a decelerometer instrument to measure braking efficiency.]
