Commercial Vehicle Operators’ Safety Manual


Appendix E Ontario Guidelines for Bus, Accessible Vehicle and School Purposes Vehicles.


National Standard NSC 11B January 2006 Ontario’s Guidelines

Introduction The bus section of the National Standard applies to buses, school-purposes vehicles and accessible vehicles, as defined in Regulation 611.Operators, of accessible vehicles should review and be aware of the additional manufacturer and on-road requirements under Regulation 629, Accessible Vehicles, under the Highway Traffic Act.
Section 3
Item 1
Parking Brake National Safety Code standard requires the parking brake to be inspected by applying the parking brake with the engine running at approximately 800 rpm.
The ministry recommends that this test be performed at idle, and not 800 rpm.
In some cases, motor vehicles equipped with automatic transmissions are programmed so that the parking brake is automatically disengaged when the transmission is placed in a forward or reverse gear. In such cases, it is not possible or required to check the parking-brake performance by this method.
Section 3A
Item 16f
Mechanical Components (slack adjusters) Clarification:
A push-rod travel indicator has been a manufacturer’s requirement since April 30, 1995, in Ontario (Regulation 587), and a federal requirement for Canada (Technical Standards Document Number 121) since May 31, 1996. Therefore, air-brake vehicles manufactured after May 31, 1996, that are equipped with external adjustment mechanisms and an exposed push rod must be equipped with an indicator that indicates when the push-rod travel exceeds the prescribed adjustment limit.
Most-air brake chambers with exposed push rods are manufactured with markings directly on the base of the push rod so that the markings are exposed when an over stroke condition exists – this complies with the manufacturing standards.
Some vehicles have brake-stroke indicators that are more visible, to assist drivers in determining the pushrod stroke of a brake. These devices are optional, and can replace or supplement the indicators required at time of vehicle manufacture.
Section 4
Item 1
Steering Wheel Test MTO recommends that mechanics be aware and advise clients, when appropriate, that the on-road standard under Regulation 611 is more stringent than the National Standard in the amount of allowable steering lash.

Less than 350 millimetres 45 millimetres
350 millimetres and larger, but less than 400 millimetres 50 millimetres
400 millimetres and larger, but less than 450 millimetres 55 millimetres
450 millimetres and larger, but less than 500 millimetres 60 millimetres
500 millimetres and larger 70 millimetres
