The Federal Motor Carrier Safety Administration has expanded the windshield area inside a truck cab where a driver can position a GPS navigation device. These units can now be placed up to 4 inches below the upper edge of the windshield wiper sweep, or up to 7 inches above the wiper’s lowest sweep. The expanded area matches the zone already allowed for mounting “vehicle safety technology”, but GPS devices had not been included in the regulation allowing windshield mounting in this area. FMCSA believes the driver’s ability to scan a GPS device in this area will enhance safety because the driver will not have to divert his attention as far from the roadway. The agency “strongly encourages CMV drivers” to program the navigator before starting to drive, pull over and stop the truck to reprogram it, and use the device’s voice guidance.
