State law now requires both adults and children to be buckled up in the front or back seat. A child less than 8 years old, unless taller than 4 feet 9 inches, must ride in a child safety seat. Most children between 4 and 8 years old will need a booster seat to be safe and comply with the law. Fines range from $25 to $250, plus court costs. TexasClickitorTicket.com
