How common is the use of police radar?
Since the mid seventies radar has served as the tool of choice for speed enforcement. Over 100,000 radar units are in service by police in all 50 states and account for over 37,000,000 speeding tickets each year. In fact, there are so many radar guns on the road today, your speed may be radar monitored more than fifteen times during a single trip from New York to Los Angeles.
