Abstract
The National Transportation Safety Board determines that the probable cause of this accident was a combination of events involving (1) the erratic driving by the intoxicated driver of a passenger vehicle which stopped in a through traffic lane creating a traffic obstacle; (2) the inattention of tie truck driver causing his vehicle to strike the passenger vehicle; and (3) the bus driver's overtaking the truck too rapidly to enable him to avoid striking the passenger vehicle when it unexpectedly appeared in the path of his bus.
