- Title
SCIENTIFIC EVIDENCE IN TRAFFIC CASES.

- Abstract
This article discusses several scientific methods to determine evidence in traffic cases. Speed and drinking are two influential factors contributing to deaths on the highways. In 1966, over 50,000 persons in the U.S. lost their lives as a result of traffic accidents. Of the fatal accidents which occurred, speed was a contributing factor. Suggestions have been made that alcohol is causally related to approximately fifty percent of fatal accidents in the country. The most common speed detection device used by law enforcement agencies is the radar speed-meter. When a speed violator passes the radar car, the radar operator or another police officer in the radar car radios the pickup car down the road and this latter car apprehends the speeder. Four general methods have been developed by scientists to measure alcoholic concentration in the blood. They are chemical analyses of the four bodily substances: blood, urine, saliva and breath. Science has discovered that determination of the blood alcohol concentration will show the influence of alcohol on the person's driving ability. Basic problems arise in the practical application of any scientific device or test. The principles of the radar speedmeter or the breathalyzer may be sound. Yet, the practical on-the-spot operation of these devices may fail to account for all relevant factors.
