scope:

SUMMARY: In an August 2005 final rule, we updated our standard regulating motor vehicle controls, telltales and indicators. The standard specifies requirements for the location, identification, and illumination of these items. In May 2006, we published a response to four petitions for reconsideration, including one asking us to reconsider a requirement for color contrast between identifiers and their backgrounds. We denied this petition for reconsideration.

In response to another petition for reconsideration from the Alliance of Automobile Manufacturers (the Alliance) of the color contrast requirement, specifically for the horn control identifier, in this final rule, we amend the standard to provide that an identifier is not required if the horn control is placed in the middle of the steering wheel. If the horn control is placed elsewhere in the motor vehicle, the control would be required to be identified by the specified horn symbol in a color that stands out clearly against the background.
