A contractor repairing a highway owes a duty of care to motorists using the highway.  The duty of care extends to protecting motorists from dangers on property adjacent to the repairs the contractor is performing.  See Ray v. Silverado Constructors (2002) 98 Cal.App.4th 1120, 1134; Thirion v. Fredrickson & Watson Construction Co. (1961) 193 Cal.App.2d 299, 304-305,  Here, the contractor breached that duty of care by stopping northbound traffic in a manner that allowed the stopped cars to block an intersection, thus preventing southbound traffic from turning into the cross-street.  Plaintiff was stopped behind a car which was waiting to make that turn when he was rear-ended by an unobservant driver.
