Gov. Nikki Haley vetoed a moped safety bill this week because she says it requires reflective vests for nighttime driving and helmets for drivers under 21.
According to the Associated Press, Haley said the mandates on adults are government overreach.
The bill would close a loophole that prevents intoxicated moped drivers from being charged with drunken driving. People who lose their license due to a DUI could still drive a moped, but they must get a special moped license under the legislation.
The Department of Public Safety says 50 people died in moped crashes last year, up from 32 in 2014. At least 16 have died this year.
