A bill affecting teen drivers was approved in the Iowa Senate Wednesday
Senate File 115 would increase the amount of time teens remain on an instruction permit from six month to 12 months. When that year is up, the teen would get their intermediate license.
The bill would also limit the number of non-related passengers in a vehicle driven by a teen.
However, an amendment would allow parents or guardians to sign a waiver on that rule.
The bill now goes to the House for a vote.
