Enforcement of the updated safety seat law that went into effect last fall starts June 1st! If you have a kiddo 8 or under that is shorter than 4'9" - they need to be in a safety seat. Fines range from $25-$250. Guidelines for safety seats can be found on the Texas Department of Public Safety website:
