how old does a child have to be to sit in the front seat of a car ?
Question: What is the law regarding the age and or weight a child should be before they can ride in the front seat? Answer: Michigan law requires children younger than age 4 to ride in a car seat in the rear seat if the vehicle has a rear seat. If all available rear seats are occupied by children under 4, then a child under 4 may ride in a car seat in the front seat. A child in a rear-facing car seat may only ride in the front seat if the air bag is turned off.
