[New Hampshire EPAMD law] 269:3 Equipment.  An EPAMD shall be equipped with front, rear, and side reflectors; [Comments] The provision for the EPAMD is rudimentary. Unlike with bicycles, no standard for design or performance of the reflectors is specified. Unlike with bicycles, there is no provision to allow a peace officer to inspect an EPAMD. Also, unlike with bicycles, there is no prohibiting the EPAMD from use if the equipment is in unsafe condition. A cube-corner reflector works within only a limited range of entrance angles. (See explanation on another page.) The Segway's tilting backward and forward would render a front or rear cube-corner rear reflector invisible when the Segway is braking or accelerating, or climbing or descending a steep slope. As the Segway's tilting does not follow the slope, any compensatory mechanism would require a slope sensor. Glass-bead reflectors do not have the angle limitation, but on the other hand, the Segway law says nothing about the type of reflector required. [New Hampshire bicycle law]
