Modifies provisions relating to child safety seat requirements

HB 2261 updates Missouri's child passenger safety laws by clarifying age and weight requirements for using car seats and booster seats. The bill mandates that children under two must ride in rear-facing seats, while those under four or weighing less than forty pounds must use an appropriate restraint system regardless of age. It also specifies that children between four and eight years old who weigh at least forty pounds must use a booster seat or vehicle safety belt, and it removes previous height restrictions for children over eight years old. Drivers who violate these rules face a fine of up to fifty dollars, but the law excludes public carriers and students on large school buses. Additionally, the bill requires the state to launch a public education program to help families understand and follow the new safety guidelines.
