SAN FRANCISCO (AP) — The National Transportation Safety Board has issued a safety recommendation urging California transportation officials to move faster to repair highway safety barriers damaged by vehicles.

The NTSB recommendation Monday comes in a report that says California officials failed to fix a highway safety barrier before a fatal March 2018 collision in a Mountain View crash that killed an Apple engineer. The barrier had been damaged 11 days before the Tesla in Autopilot mode crashed into it.

The federal agency says it previously identified problems in a fatal 2016 crash in San Jose when a barrier damaged 44 days earlier had not been fixed.

California Department of Transportation spokesman Matt Rocco says the department is reviewing the NTSB report to determine its next steps but declined to answer questions.
