In Texas, the law requires all passengers in a vehicle to wear seat belts or face penalties and court fees of up to $200. Unless they are higher than 4 feet 9 inches, children under the age of 8 must ride in a child safety seat or booster seat. If they are not properly secured, the driver might face fines of up to $250, plus court fees. Children between the ages of 8 and 14 need to be belted into a seat belt, while those over 14 require a waiver signed by their parents to sit in the front seat. The cost of a ticket for failing to use a seat belt varies by county in Texas. In Denton County, it costs $35 to appear in court and $65 to pay a fine online. In Tarrant County, the cost is $40 and $80, respectively. In Harris County, there are three levels of offense for not wearing a seat belt: Class C misdemeanor ($20), Class B misdemeanor ($240), and felony ($300). A first offense will probably be handled with a written warning; a second offense within five years may result in a fine of $175 or more. A third offense within eight years can lead to imprisonment. Children who aren't properly restrained are at increased risk of injury in an accident. The most common injuries associated with seat belt non-use include broken bones and internal organ damage.
