Federal Motor Carrier Safety Administration (FMCSA), DOT.


Notice of application for exemption; request for comments.


The Federal Motor Carrier Safety Administration (FMCSA) requests public comment on an exemption application from Stoneridge, Inc. (Stoneridge) to allow motor carriers to operate commercial motor vehicles (CMVs) with the company's MirrorEyeTM Camera Monitor System (CMS) installed as an alternative to the two rear-vision mirrors required by the Federal Motor Carrier Safety Regulations (FMCSRs). Stoneridge Start Printed Page 14717explained that it has developed, tested and manufactured the CMS to improve CMV safety by providing driver with an enhanced field of view around the cab of the truck. The company states that its MirrorEyeTM CMS meets the performance requirements provided for conventional mirrors under the National Highway Traffic Safety Administration (NHTSA)'s standards which are cross-referenced by the FMCSRs. Stoneridge believes the exemption would maintain a level of safety that is equivalent to, or greater than, the level of safety achieved without the exemption because CMS meets or exceeds the performance requirements for traditional mirrors.

End Further Info End Preamble Start Supplemental Information



Under Agency regulations, FMCSA must publish a notice of each exemption request in the Federal Register (49 CFR 381.315(a)). The Agency must provide the public with an opportunity to inspect the information relevant to the application, including any safety analyses that have been conducted. The Agency must also provide an opportunity for public comment on the request.

The Agency reviews the safety analyses and the public comments and determines whether granting the exemption would likely achieve a level of safety equivalent to or greater than the level that would be achieved by the current regulation (49 CFR 381.305). The decision of the Agency must be published in the Federal Register (49 CFR 381.315(b)). If the Agency denies the request, it must state the reason for doing so. If the decision is to grant the exemption, the notice must specify the person or class of persons receiving the exemption and the regulatory provision or provisions from which an exemption is granted. The notice must specify the effective period of the exemption (up to 5 years) and explain the terms and conditions of the exemption. The exemption may be renewed (49 CFR 381.315(c) and 49 CFR 381.300(b)).

Stoneridge Application for Exemption

Stoneridge has applied for an exemption from 49 CFR 393.80(a) to allow its MirrorEyeTM CMS to be installed as an alternative to the two rear-vision mirrors required on CMVs. A copy of the application is included in the docket referenced at the beginning of this notice.

Section 393.80(a) of the FMCSRs requires that each bus, truck, and truck-tractor be equipped with two rear-vision mirrors, one at each side. The mirrors must be positioned to reflect to the driver a view of the highway to the rear, and the area along both sides of the CMV. Section 393.80(a) cross-references NTHSA's standards for mirrors on motor vehicles (49 CFR 571.111, Federal Motor Vehicle Safety Standard [FMVSS] No. 111). Paragraph S7.1 of FMVSS No. 111 provides requirements for mirrors on multipurpose passenger vehicles and trucks with a gross vehicle weight rating (GVWR) greater than 4,536 kg and less than 11,340 kg and each bus, other than a school bus, with a GVWR of more than 4,536 kg. Paragraph S8.1 provides requirements for mirrors on multipurpose passenger vehicles and trucks with a GVWR of 11,340 kg or more.

The MirrorEyeTM CMS consists of multiple digital cameras mounted on the exterior of the CMV and enclosed in an aerodynamic package that provides both environmental protection for the cameras and a mounting location for optimal visibility. Each camera has video processing software that presents a clear, high-definition image to the driver by means of a monitor mounted to each A-pillar of the CMV, i.e., the structural member between the windshield and door of the cab. The company explains that attaching the monitors to the A-pillars avoids the creation of incremental blind spots while eliminating the blind spots associated with conventional mirrors. Stoneridge states that its CMS meets or exceeds the visibility requirements provided in FMVSS No. 111 based on several factors:

  • Greater field of view (FOV) than conventional mirrors—Mirrors are replaced by wide angle, narrow angle and look-down cameras expanding the FOV by an estimated 25%.
  • Fail-safe design—The CMS has independent video processing of multiple camera images so that in the unlikely event of an individual camera failure, the other camera images continue to be displayed. This ensures that real-time images are continuously displayed without interruption.
  • Augmented and enhanced vision quality—The use of high-definition digital cameras provides for color night vision, low light sensitivity and trailer panning capabilities. This assists with night driving, operating under other low lighting conditions, and provides for glare reduction.Start Printed Page 14718
  • Trailer panning—The CMS automatically tracks the end of the trailer to keep it in view while the vehicle is moving forward. Stoneridge believes this feature could eliminate collisions associated with the CMV driver making a right-hand turn, and incidents where the CMV strikes a pedestrian or bicyclist while making right hand turns.

Stoneridge also believes use of its CMS may help to reduce driver fatigue by requiring less head movement by drivers compared to the number of head movement needed to use conventional mirrors. The company claims that use of its CMS provides improved fuel economy because the housing for the system is more aerodynamic than the conventional mirrors required by § 393.80(a).

The exemption would apply to all CMV operators driving vehicles with the MirrorEyeTM CMS. Stoneridge believes that mounting the system as described would maintain a level of safety that is equivalent to, or greater than, the level of safety achieved without the exemption.
