A moped safety bill is dead after the House failed to override Gov. Nikki Haley's veto.
The 65-47 vote Wednesday fell far short of the necessary two-thirds.
The Republican governor said requiring reflective vests for nighttime driving and helmets for drivers under 21 represents government overreach.
The most vocal backer of Haley's position was House Minority Leader Todd Rutherford, normally a Haley foe.
The bill's supporters contend moped drivers are dying because people can't see them, especially at night, and the requirements will save lives.
Republican Rep. Derham Cole of Spartanburg says the bill closed a dangerous drunken driving loophole. Currently, moped drivers can't be charged with DUI because state law exempts mopeds from the definition of motor vehicle.
Cole has tried since 2010 to close that loophole.
