What is Tennessee law concerning seatbelts?

The law, country wide in the US, is that you must wear your seatbelt at all times or you can receive a ticket and/or fine. Arkansas law requires all children under the age of fifteen years who are passengers in a motor vehicle to be buckled-up. Furthermore, children younger than six years of age and weighing less than sixty pounds must be restrained in approved safety seats. Arkansas is among a group of states that require seat belt use by drivers and front seat passengers. State law requires police to have a reasonable cause other than a seat belt violation to stop a vehicle and cite a violator. However, an unrestrained child in a moving motor vehicle is considered a primary violation allowing police to stop the vehicle without another cause.
