Parts and Accessories Necessary for Safe Operation; Grant of Temporary Exemption for Innovative Electronics

Notice of final disposition.

The Federal Motor Carrier Safety Administration (FMCSA) announces its decision to grant an exemption to allow commercial motor vehicle operators to use trailer-mounted electric brake controllers which monitor and actuate electric trailer brakes based on inertial forces developed in response to the braking action of the towing vehicle. FMCSA believes that the use of trailer-mounted electric brake controllers will maintain a level of safety that is equivalent to, or greater than, the level of safety achieved without the exemption.
