Example Use:
As drivers approach a particular stretch of highway, they might notice a sign posted with the words 'Speed Checked By Detection Devices.' This sign serves as a precautionary warning, indicating that police in the area may be using radar guns or other technological equipment to monitor vehicle speeds. The presence of the sign aims to deter drivers from speeding by informing them of the likelihood of being caught if they exceed the speed limit and the issuance of a traffic citation. Consequently, aware of this potential surveillance, many drivers instinctively reduce their speed upon seeing the sign, thereby promoting road safety and reducing the risk of speeding-related accidents in that zone.
