Which types of information do SMDs typically record when measuring speed?

• A. Vehicle color and model
• B. Speed of the vehicle, date, time, and photographic evidence
• C. Only the speed and driver’s license number
• D. Weather conditions and traffic density

Answer: (B)

Speed Measurement Devices (SMDs) typically record critical information that assists in accurately determining and documenting a vehicle's speed. The correct answer includes the speed of the vehicle, along with the date, time, and photographic evidence.

Recording the speed is fundamental to SMDs as it is the primary purpose of these devices—to assess whether a vehicle is exceeding the speed limit. Additionally, capturing the date and time is essential, as these details provide context for the speed measurement, which can be crucial in legal situations, such as traffic violations. Photographic evidence further substantiates the measurement, often including an image of the vehicle and its license plate, reinforcing the evidence against the driver if needed in court.

In contrast, the other options do not encompass the essential informational elements captured by SMDs. For instance, details like vehicle color and model or solely relying on a driver’s license number do not contribute to effectively documenting speeding incidents. Weather conditions and traffic density may be relevant in specific driving analyses but are not standard recordings made by SMDs during speed measurements. Hence, the comprehensive suite of information captured by option B makes it the correct choice.
