What is a speed trap?

A speed trap is specifically defined as a location where law enforcement officers actively monitor and enforce speed limits to identify and cite drivers who exceed the designated speed. This often involves the use of various speed detection methods, such as radar or laser technology, enabling officers to measure the speed of vehicles approaching the trap. These locations are strategically chosen, sometimes in areas known for frequent speeding violations, to promote road safety and encourage compliance with traffic laws.

The other options represent different concepts related to traffic safety but do not define a speed trap. For example, a program to educate drivers is important for preventing speeding but does not involve enforcement. Similarly, a specially designed vehicle for monitoring traffic, while relevant, does not encompass the idea of a speed trap itself. Lastly, a posted speed limit serves as a guideline for drivers but does not represent the active enforcement aspect that characterizes a speed trap. Thus, the function and purpose of a speed trap are adequately summarized by its role in detection and citation of speeding drivers.
