In Kabat v. Department of Transportation, ordered published December 19, 2024, the Fourth District Court of Appeal, Division 3 affirmed summary judgment for Caltrans. A bicyclist was riding or walking her bike across a non-signalized marked crosswalk that crossed a freeway onramp when a motorist hit and fatally injured her. There was a pedestrian crossing sign facing traffic 150 feet ahead of the crosswalk and another (with a sign below it of an arrow pointing down) at the north end of the crosswalk. The crosswalk is part of an interchange owned and controlled by Caltrans. It was originally constructed by Caltrans's predecessor agency based on plans prepared and completed in 1967. It underwent improvements twice, based on plans completed in 2006 and 2015. The plaintiffs contended that the crosswalk was a dangerous condition of public property because the posted speed limit was too high, the bike path leading to it was dangerous and unsafe because it did not allow pedestrians and bicyclists a safe way to cross the highway; there were inadequate warnings and signs and insufficient traffic controls; and there was a "trap condition" where motorists approaching the onramp and pedestrians and bicyclists using the crosswalk could not see one another. The trial court granted Caltrans summary judgment, because Caltrans established design immunity under Government Code section 830.6 and plaintiffs could not overcome the signage immunities under Government Code sections 830.4 and 830.8. The trial court ruled that plaintiffs had failed to raise a triable issue of fact on the existence of a failure-to-warn claim, based on a concealed trap, that would be actionable despite design immunity.
The appellate court agreed. It rejected plaintiffs' contention that Caltrans failed to establish the discretionary-approval element of design immunity. The plaintiffs contended that Caltrans had to establish that the specific engineers who approved the 1967, 2006, and 2015 plans had been delegated or vested with discretionary authority to approve them. Caltrans presented uncontradicted evidence through the declarations of Caltrans employees and a civil/traffic engineer's declaration that licensed engineers and Caltrans design oversight engineers approved the various plans before construction. The Legislature has vested Caltrans with discretionary authority to approve highway plans and has required licensed engineers to sign off on them. Caltrans can act only through its employees or agents. The plan signatures reasonably support the uncontradicted inference that the plans received Caltrans's discretionary approval. As for the failure-to-warn claim, public entities are entitled to signage immunity unless the plaintiff establishes that the dangerous condition at issue was a concealed trap, and that the public entity had notice of the dangerous condition. The plaintiff must establish notice under a failure-to-warn theory even if the defendant entity created the dangerous condition. Caltrans offered undisputed evidence that it maintains a database tracking the number and type of collisions on its onramps; and that in the decade before and including the day of the accident there were no accidents involving a bicyclist during the same time of day as the accident, despite over 13 million vehicles passing through the onramp. This evidence established Caltrans had no notice of the alleged dangerous condition. A declaration by plaintiffs' expert that the crosswalk created a false sense of security, that the lack of a signal constituted a trap because it rendered the area deceptive, and that the Caltrans database was inadequate to provide constructive notice did not raise a triable issue of fact on notice, because the opinions were conclusory. Finally, the public entity did not have to provide evidence that it used the databases before the accident occurred to establish lack of notice.
