Action
Notice of application for exemption; request for comments.
Summary
FMCSA requests public comment on an application for exemption from Innovative Electronics regarding the use of trailer-mounted electric brake controllers, which monitor and actuate trailer brakes based on inertial forces developed in response to the braking action of the towing vehicle. While trailer-mounted electric brake controllers function like an electric surge brake, the Federal Motor Carrier Safety Regulations (FMCSRs) define a surge brake as a "self-contained, permanently closed hydraulic brake system" [Emphasis added.] As such, the use of trailer-mounted electric brake controllers on commercial motor vehicles is currently prohibited. Innovative Electronics is requesting a temporary exemption in advance of petitioning FMCSA for rulemaking to modify the current definition of a surge brake.
