What scientific advancement was introduced in 1910 for speed detection?

  1. The Radar Gun

  2. The Photo-Speed Recorder

  3. The Speed Trap

  4. The Distance Measuring Device

The correct answer is: The Photo-Speed Recorder

The introduction of the Photo-Speed Recorder in 1910 marked a significant advancement in speed detection technology. This device utilized photographic techniques to automatically capture images of vehicles as they exceeded speed limits, effectively synchronizing a camera with a timekeeping mechanism. This innovation allowed for the accurate recording of a vehicle's speed without requiring a direct visual observation by law enforcement. As a result, it enhanced the enforcement of speed limits, providing a more reliable means to measure and document speeding violations. While other speed detection methods, like the radar gun, emerged later and offered their own advantages in detecting speed, the Photo-Speed Recorder was pioneering for its time. It laid the groundwork for future advancements in speed measurement and traffic law enforcement, solidifying its place in the history of speed detection technology.
