What feature differentiates mobile speed measurement devices?

• A. They are permanently installed
• B. They can be easily relocated as needed
• C. They are only used in highway patrol
• D. They do not require calibration

Answer: (B)

Mobile speed measurement devices are characterized by their ability to be easily relocated, which allows law enforcement to adapt their speed enforcement strategies based on varying conditions or specific areas where speeding is a concern. This mobility enables officers to set up speed traps in different locations to effectively monitor traffic and enforce speed limits as necessary, responding dynamically to traffic patterns and problem areas.

In contrast, permanently installed devices are fixed in one location, limiting their flexibility and adaptability compared to mobile units. Additionally, while mobile devices are often used by highway patrol, their use is not restricted solely to that context. Calibration is a critical aspect of speed measurement devices to ensure accuracy, regardless of whether the device is mobile or fixed. Therefore, the unique advantage of mobile speed measurement devices lies in their capacity for relocation, which enhances their effectiveness in promoting road safety.
