Whether or not a 17-year-old can drive minors around depends on the state they are driving in, what stage their license is in (learner’s permit, intermediate license, or unrestricted license), if the minor is an immediate family member, and if supervision is present. If they have an unrestricted license, they are allowed to drive minors around.
If they only have a learner’s permit, their ability to drive minor passengers is restricted. Many states only allow minors to ride along if they are immediate family members or if a supervising adult is present. Check your state’s laws to find out if your teen can drive a minor based on their license type.
