DES MOINES, Iowa (AP) — Iowa’s teen drivers would face tougher rules under a bill that passed the Senate. Senators approved the legislation in a 41-8 vote Wednesday. Under the plan from Democratic Sen. Tod Bowman, drivers under the age of 18 would need to hold a learner’s permit for a full year before getting a license.

Teen drivers also would not be able to transport more than one unrelated minor, unless they are with a parent, guardian or driving instructor, for the first six months they hold a license. Parents could sign a waiver so the passenger rules would not apply to their kids. Bowman says teen drivers are far more accident-prone than older motorists. The bill now moves the House where lawmakers must provide approval.
