‘Black Box’ Data Recorders in Buses, Trucks Vital for Highways Safety

Following the investigation of a fiery crash in California -- where a cause could not be determined -- the National Transportation Safety Board is calling on commercial bus and truck manufacturers to install data recorders to aid investigators.

(TNS) -- WASHINGTON — The National Transportation Safety Board on Tuesday called on commercial bus and truck manufacturers to install data recorders after investigators couldn’t find the cause of a fiery crash last year in California that killed 10 people.

The NTSB said it was unable to determine why a southbound tractor-trailer crossed the median of Interstate 5 near Orland, Calif., about 100 miles north of Sacramento, striking a northbound charter bus full of high school students from southern California on a college tour.

NTSB Chairman Christopher Hart noted that the presence of “black box” recorders in commercial aviation had been a vital tool for decades in investigations that helped the board make recommendations to prevent future accidents.

He added that despite “more than a decade of recommendations by the NTSB,” federal regulators at the U.S. Department of Transportation had not required them in large motor vehicles.

“With access to event data recorders,” Hart said, “we might have been able to determine why the truck crossed the median, which could have enabled us to make recommendations to prevent it from happening again.”

Both drivers were killed in the April 10, 2014, crash, as were eight passengers on the bus. Many couldn’t escape the bus as it was quickly engulfed by fire, fed by leaking fuel from the truck.

The crash blocked the front exit, forcing passengers to escape through windows that were seven feet off the ground and didn’t stay open. The bus also lacked adequate lighting and signage to direct passengers through the accumulating smoke.

“It is unacceptable for anyone who survives a crash to perish in a post-crash fire because the exits were too hard to find or too difficult to use,” Hart said.

In a synopsis of its forthcoming accident report, the board said that the federal flammability standard for buses is “outdated” and doesn’t match standards used in commercial aviation and passenger rail.

A message left for the American Bus Association wasn’t answered, but the group has expressed support for the installation of data recorders.

Sean McNally, a spokesman for the American Trucking Associations, said that the industry trade group “supports the use of many technologies, including event data recorders, that can positively impact safety.”

He added that access to such data should be safeguarded to ensure privacy and that all vehicles, not just trucks and buses, should be so equipped.

In the California crash, NTSB investigators were able to rule out the drivers’ experience, licensing and training; drug or alcohol use; mechanical failures or weather in the crash. They also found no evidence of fatigue or distraction.

Cable median barriers were not installed on the stretch of interstate where the crash took place, devices credited with preventing crossover crashes.

The NTSB found that the crash location’s average daily traffic and crash history didn’t warrant median barriers under California’s standards, which exceed federal requirements.

More than 300 cross-median crashes took place on interstate highways in 2012, according to the National Highway Traffic Safety Administration.
