What type of survey collects data through direct observations of behaviors, like seatbelt wearing?

The choice of an observational survey is appropriate because these surveys are specifically designed to gather data by directly observing participants' behaviors in real-world situations. In the context of road safety, this approach allows researchers or practitioners to accurately record how many individuals are wearing seatbelts without relying on self-reported data, which may be biased. This method provides objective evidence of behavior, making it a valuable tool for assessing compliance with safety regulations and understanding user habits on the road.

Observational surveys are particularly effective in situations like evaluating seatbelt usage because they capture actual behavior rather than what individuals claim they do. This can provide more reliable data to inform road safety initiatives and policies aimed at increasing seatbelt usage and reducing fatalities and injuries.
