NHTSA is looking for truck drivers to test the safety of in-cab cameras.
DOT safety group seeks comment on replacing rearview mirrors with cameras.
Trucks without mirrors are entering the testing phase, but they could soon become a reality.
The regulatory body granted Stoneridge a five year exemption to install its MirrorEye camera monitoring system on trucks in lieu of two rear-view mirrors.
The FMCSA has formally moved to exempt the MirrorEye Camera Monitor System (CMS) from Stoneridge from federal regulations as the company seeks to begin on-road testing of the system on vehicles without side mirrors.
