Firefighters used 50,000 gallons of water to put out Tesla Semi fire in California: U.S. agency

California firefighters used about 50,000 gallons of water to put out a Tesla Semi fire after a collision, the National Transportation Safety Board said on Thursday.

According to the Associated Press, an aircraft also dropped fire retardant on the “immediate area” to bring the fire under control, the agency reported.

The battery hit temperatures of 1,000 degrees Fahrenheit while it was on fire.

The truck hit a tree while going around a curve on Aug. 19. Tesla's autopilot feature was not engaged, according to the agency report.

The NTSB said it would examine the battery for potential issues that pose fire risks.
