All vehicles manufactured after September, 2005, will have advanced frontal airbags.

The correct answer is that it is false that all vehicles manufactured after September 2005 will have advanced frontal airbags. While the law mandated that all vehicles must have some form of airbags after this date, the definition and implementation of "advanced" frontal airbags can vary. Advanced frontal airbags are designed to deploy differently based on the weight and position of the occupant, enhancing safety measures especially for children or smaller individuals. However, not all vehicles may incorporate these sophisticated systems; some may only have standard airbags that do not adjust deployment based on occupant characteristics.

Legislative requirements for airbags can also differ by vehicle category (such as passenger cars versus trucks), and manufacturers may have options regarding the inclusion of advanced technologies based on their design and market decisions. Therefore, while advanced frontal airbag systems became more common after this date, it is not accurate to state that every vehicle manufactured after September 2005 is equipped with them.
