New federal standards for "black boxes" that record information leading up to auto accidents will will take effect Sept. 1, the National Highway Traffic Safety Administration (NHTSA) ruled on Tuesday.
The decision means the new standards for the devices will not be delayed by one year, as automakers had requested.
NHTSA standards for black boxes were proposed in 2006, but have been delayed since then. In 2009, the Alliance of Automobile Manufacturers suggested a delay to Sept. 1, 2013, arguing that this would give auto companies more time to work with original equipment manufacturers to ensure the standard can be met.

But NHTSA rejected this, arguing that the rule has already been delayed, and that it has already adjusted the standard in a way that should make it easier for companies to comply.
"The petitioner suggested that the delay would enable vehicle manufacturers to retain current EDR functionality across all vehicle models and avoid disabling legacy EDR systems for a limited number of vehicle models," NHTSA said in its Tuesday decision. "The agency is denying the petition since the implementation of the August 2006 final rule has already been delayed by two years and we have recently published a final rule responding to the remaining petitions for reconsideration."
NHTSA has been considering the next step — a requirement that all cars are built with black boxes — since 2011. In anticipation of this requirement, some in Congress have proposed legislating the mandate ahead of time.
The initial version of the highway bill that the Senate approved in April included language that would have required the secretary of Transportation to evaluate event data recorders and ultimately require their installation on all cars within a few years.
But due to Republican opposition and concerns about privacy, that language was eventually stripped out in a House-Senate conference that passed in late June.
