Intrusion

In the majority of cases, the minor injuries sustained by occupants in sometimes severe crashes indicate that the presence of seat belts on the buses would have made little difference to the outcome. However, this is not always necessarily the case.

The sample represented 42 cases involving 567 students. Five bus occupants were fatally injured, two due to a side impact by a dump truck, one as a result of an external object penetrating the occupant compartment, and two in a collision-induced fire. Twelve children who had disembarked from their buses were killed, 11 being run over by the bus, and 1 who was struck by a vehicle passing the bus.

Executive Summary

Rationale

In late 2005, the Canadian Trucking Alliance (CTA) called on the federal and provincial governments to mandate the activation of speed limiters on all heavy trucks traveling into or within Canada at no more than 105 kilometres per hour (kph).

United States

As with any vehicle, respect the posted speed limit, slow down when the weather and/or road conditions are poor, and slow down before entering sharp curves. Don't tailgate; always give yourself enough room in front of you to react to sudden events such as animals or vehicles entering your lane. Take extra care when you drive on rural roads because of on-coming and passing traffic.

6. DATA RECORDING AND ANALYSIS

6.1. Data Recording Equipment
Each test was recorded and the data were analyzed using the following equipment:

5. TEST METHODOLOGY

Tests were performed with three state-of-the-art fully instrumented dummies. Two dummies were selected to represent preschool-aged children, while one represented a small school-aged child. These dummies and the size of children they represent are presented below.

The head and chest accelerations of the dummies were measured for each test. Because injury reference levels have not been adopted for children,¹⁹ the upper and lower neck forces and moments and shoulder loads were not analyzed.
