Safe transportation is a critical element of full community participation for persons with physical disabilities. Transportation vehicles must be designed to provide optimal safety and security for passengers with a range of physical disabilities. This fourth edition of CSA D409 is intended to provide guidance on design and safety of motor vehicles - excluding passenger cars, transit vehicles and intercity motor coaches - operated for, or on behalf of, any person, club, agency, or organization that provides a transportation service for persons with physical disabilities.
First published in 1984, this latest edition has several critical updates and changes including the exclusion of school buses - as they are covered in CSA D250 School Buses- and the elimination of basic manufacturing requirements and modified weight ranges. In addition, CSA D409 makes reference to several motor vehicle safety regulations (MBSR) contained in federal regulations.
Highlights of D409:
- Specifies design and manufacture of vehicle, lifts and ramps
- Outlines required safety equipment
- Specifies modified weight ranges for various vehicle sizes, harmonized with U.S. classification scheme
- Addition of provisions for vehicles powered with alternative fuel systems
- Clearly outlines modified design requirements for mobility aid securement and occupant restraint (MASOR) systems including positioning and anchor points of systems
This is the fourth edition of CSA D409, Motor Vehicles for the Transportation of persons with physical disabilities. It supersedes the previous editions published in 2002, 1992 and 1984.
The scope of this edition, has been reduced to no longer address school buses. Provisions for accessible school buses are now covered in CSA D250.
It is intended that this Standard be applied to motor vehicles operated for, or on behalf of, any person, club, agency, or organization that provides a transportation service for persons with physical disabilities. This Standard does not apply to transit vehicles and intercity motor coaches.
This Standard makes reference to several motor vehicle safety regulations (MVSR) contained in federal regulations. The applicability of some MVSR requirements is dependent on the gross vehicle weight rating (GVWR) of the vehicle. Some MVSR requirements apply to vehicles having a GVWR of 4536 kg (10 000 lb) and under, while some apply to vehicles having a GVWR of over 4536 kg (10 000 lb).
Note: In order to accommodate common vehicle sizes, this Standard has adjusted this threshold to 4581 kg (10 100 lb).
Many of the basic vehicle design and performance requirements found in the MVSR and the affiliated Federal standards, included in the 2002 edition of D409, have been removed from this edition (with the many references to the MVSR, these are now considered redundant). In addition, basic manufacturing requirements not related to safety or accessibility have been eliminated from this Standard.
The following are other significant changes made in this edition:
a) modified weight ranges for various vehicle sizes (harmonization with U.S. classification scheme);
b) added provisions for vehicles powered with alternative fuel systems;
c) modified design requirements for mobility aid securement and occupant restraint (MASOR) systems (Clause 7.2.2);
d) modified requirements for the positioning of MASOR systems (Figure 3); and
e) modified requirements for the anchor points for MASOR systems (Figure 4).
This Standard applies to motor vehicles other than passenger cars (as defined in Section 2 of the Motor Vehicle Safety Act) designed and manufactured, or converted, and equipped for the purpose of transporting persons with physical disabilities.
This Standard specifies
a) the design and manufacture of the vehicle, lifts, and ramps;
b) the mobility aid location and securement; and
c) the required safety equipment.
This Standard does not apply to any transit bus and any over-the-road bus.
This Standard also does not apply to school bus (see CSA D250).
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
