The Utah Highway Patrol has acquired the latest in speed-detection technology to outwit those "fuzzbusters."

Utah Highway Patrol Trooper Bruce Provost said Vascar Plus works on the principle of averaging time and distance. For example, if a motorist is traveling at a speed higher than the posted speed limit and then tries to slow down when a patrol car is in sight, Vascar Plus will average the two speeds and determine if the motorist has broken the law.Unlike years before when motorists equipped with radar detection devices could be forewarned of a police vehicle in the vicinity, the Vascar Plus system works without a radar signal and therefore cannot be detected by a passing motorist.

"A driver can have 24 fuzzbusters in the car and it won't do any good," Provost said.

Provost said the system has been around for some time, but the modified, more sophisticated system now being tested in Utah has been in use only about 30 days.

Vascar Plus, which stands for Visual Average Speed Computer and Recorder, is being used in only two Utah Highway Patrol cars during the experimental stage.

"Right now, we're just experimenting with the system, trying to determine if it's something we might want to look into," Provost said. "But with Salt Lake City's heavy traffic flow, it's very, very applicable to this area."

Provost added that Vascar Plus could prove beneficial in less-populated areas of the state in determining whether motorists are traveling too close behind another.

"For example, if a vehicle is traveling on I-15 through Parowan, Vascar Plus can measure the distance that cars are following behind another and determine if they are following too closely," Provost said.

Vascar Plus can also prove useful in accident investigations, measuring the distance of skid marks and travel distance of each vehicle involved.

Provost said one of the benefits of Vascar Plus is cost - it is a less-expensive system than traditional police radar and offers additional options to help law enforcement officers detect speeding motorists.
