  9. Why do hybrids qualify for the decal and not other low-emission vehicles?

    Traditionally, only vehicles with two or more occupants have been allowed to travel in HOV lanes. In Tennessee, those lanes are in effect during morning and afternoon rush hours. On August 10, 2005, a new federal transportation act was signed into law and included an exemption from the HOV occupancy requirements for vehicles certified as "low emission and energy-efficient," (Section 1121). The new provision required the EPA to issue regulations for certifying vehicles as "low emission and energy-efficient." These provisions are codified at 23 United States Code (U.S.C.) 166. A list of EPA qualified vehicles can be found on the TDOT Smart Commute Web site.
  10. What do people do if they lose their sticker?

    Persons who lose their stickers should fill out a new application form and indicate the word "replacement" at the top of the application form.
  11. When did Smart Pass legislation go into effect?

    Public Chapter 1121 was passed in the 2008 session with an effective date of January 1, 2009 for the Smart Pass program. Tenn. Code Ann. 55-8-188 goes into detail about HOV lane regulations, including Smart Pass.
