Which of the following is an example of a targeted law?

The example of a targeted law is represented by the regulations regarding child safety seats. Targeted laws are designed to address specific issues that affect particular populations or demographics. In this case, laws concerning child safety seats focus on the well-being of children during vehicle transportation. They aim to reduce injury and fatalities among young passengers by mandating the use of appropriate safety equipment based on age, weight, and height.

This type of legislation directly targets the protection of children, making it a prime example of a law meant to safeguard a specific vulnerable group. The focused approach of such laws ensures that particular health concerns, like child safety in vehicles, are adequately addressed, promoting better health outcomes for that segment of the population.

While city-wide smoking laws, blood pressure screenings in school, and lead disclosure forms are important public health initiatives, they don't target a specific group in the same way that child safety seat regulations do. Smoking laws are more general public health laws, screenings are services provided to many, and disclosure forms serve a more informational purpose without the same level of focused protection.
