In Colorado and other states, police units have begun relying on laser technology to monitor the speed of drivers and to ticket those who are exceeding the speed limit. While many law enforcement agencies hail the developing technology as a benefit, many drivers aren’t so sure that the benefits outweigh the costs.
For many years, police have used “radar guns” to monitor and calculate the speeds of vehicles. Rather than shooting a projectile, these “guns” use radar signals to identify where a vehicle is and approximately how fast it is going. Radar guns have their limitations, however. One major limitation of radar technology is that radar signals form a cone shape as they travel away from the detector – meaning that the farther away a vehicle is, the less likely the radar gun’s measurement of its speed will be accurate.
