3. (c)A State may obligate funds apportioned under subsection (b) for any project eligible for assistance under this title.
4. (d)The Federal share of the cost of a project funded under this section shall be 100 percent.
5. (e)
   1. (1)On October 1, 2006, and October 1 of each fiscal year thereafter through fiscal year 2011, if a State has not enacted or is not enforcing a law described in subsection (a), the Secretary shall withhold an amount equal to 8 percent of the amounts to be apportioned to the State on that date under each of paragraphs (1), (3), and (4) of section 104(b).1 See References in Text note below.
   2.

   1. (1)There are authorized to be appropriated out of the Highway Trust Fund (other than the Mass Transit Account) to carry out this section $55,000,000 for fiscal year 1998, $65,000,000 for fiscal year 1999, $80,000,000 for fiscal year 2000, $90,000,000 for fiscal year 2001, $100,000,000 for fiscal year 2002, $110,000,000 for fiscal year 2003, $110,000,000 for fiscal year 2004, and $110,000,000 for fiscal year 2005 $91,315,068 for the period of October 1, 2004, through July 30, 2005.2 So in original.
