Ohio Revised Code Section 4511.81 states:
A child who is either less than four years of age or weighs less than forty pounds or is in both categories must be in a child restraint system when being transported in your vehicle.
A child who is less than eight years of age and less than four feet nine inches in height must be secured in a booster seat.
A child who is at least eight years of age but not older than fifteen, shall utilize the occupant restraining device of the motor vehicle.
There are some exceptions to this section such as taxi cabs and public safety vehicles and if the child qualifies for more than one category.
With the front air bags and inflatable side curtains that are now installed in vehicles, it is imperative the occupant restraint devices be utilized or further bodily injuries could occur during a collision.
As of October 2009, you are now required to have the headlights of the vehicle you are driving turned on whenever the vehicle's wipers are being used because of precipitation on the windshield. Ohio law also states the headlights are to be on from sunset to sunrise and at any time there is insufficient natural light or unfavorable atmospheric conditions.
