If manufacturers put event data recorders in cars and light
trucks, they must notify the buyer that the EDR is there. That’s the ruling the
National Highway Traffic Safety Administration handed down on Monday.
An EDR records crash data – like speed, braking and air bag
deployment – in the seconds during and after a crash. Investigators can use the
data to reconstruct what happened.
NHTSA spokesman Eric Bolton told “Land Line Now” on XM
Satellite Radio that when the agency looked at commentary received when the
rule was first proposed, it found that people don’t like it when they get an
EDR and are not told about it.
“We believed there was anecdotal evidence that people did
not know EDRs were in their vehicles,” said Bolton. He added that the
requirement is designed to assure that manufacturers note the EDR in the
Bolton said the owner’s manual tells people about the
vehicle they’ve just bought and that it is NHTSA’s view that the presence of an
EDR should certainly be in the owner’s manual.
The safety advocacy group Public Citizen is criticizing
NHTSA, pressing that all new cars be equipped with an EDR.
Instead, the agency just required that if a manufacturer
voluntarily installs EDRs, if must notify the buyers.
The new federal requirement takes effect for models
manufactured beginning 2011.
An EDR is different from an electronic on-board recorder.
The EDR only activates during a crash, whereas the on-board recorder is on
constantly and provides real-time information on speed, direction and exact
NHTSA says it will take up the issue of EDRs for heavy
trucks and buses later on.
