Bus v. Car - Bus Driver Shown to Have Fault

In this collision, a car blew the Stop sign and was struck on the right side by a bus as the car crossed the through street. A passenger in the car was seriously injured. Our investigation was conducted to determine if the bus driver’s driving was improper in a manner that was a cause of the collision.

Impact was the front of bus to the right side of the car. Both vehicles rotated from impact, in opposite directions: the bus rotated clockwise and the car rotated counter-clockwise. The bus and car aligned and traveled diagonally across the through street. The bus mounted the sidewalk and the front of the bus hit into the corner of a private property retaining wall. This made a U-shaped impression on the front of the bus. The bus rotated clockwise from this impact, pushing the car into a tree and making a vertical indent on the left side of the car. The car also mounted the sidewalk, but did not reach the property wall.

We determined the speeds of both vehicles and the position of both vehicles at points of time prior to impact. Based on a bus driver training manual, we determined that the bus speed was too high for the given street conditions and that the bus was not properly positioned in the street. The too high speed was shown to be a cause of the collision.

The bus driver testified that she did not see the car before impact. We determined that there was sufficient time and distance for her to have seen the car (even at the speed travelling), stop, and avoid this collision, and that the bus driver’s inattentive driving was a cause of this collision.
