State Automobile Casualty Underwriters v. Ruotsalainen

On August 30, 1962, the defendant Lee, an employee of the defendant Ruotsalainen, a contractor engaged in road building, was driving a gravel truck owned by his employer and towing a two-wheel trailer also owned by him. The trailer was originally a house trailer, but had been converted by remodeling into a tool trailer and used on various road jobs to store tools and supplies needed on these projects. It is referred to in the evidence as a "Dot" trailer. On the day in question the truck and trailer were being driven from a job site in Wyoming to a new base of operations in South Dakota.
