For drivers 16 years old, who can be considered family?

Question

I am a 16 year old new driver, and I know that the law, at least here in Ohio, is that any driver 16 years old can only have 1 non family member in the car, but they can have as many family members. Well, I was wondering would step siblings and half siblings be considered family? Because cousins don't count as family, so I was wondering who can be considered family

Answer 1

Everyone that lives with you or that are related to you.

Answer 2

i think both siblings and half-siblings count as family
