When multiple vehicles are in range, which vehicle's speed will radar most likely identify?

The speed that radar is most likely to identify is associated with the vehicle that has the largest profile. Radar operates by sending out a wave and measuring the time it takes for that wave to bounce back after hitting an object. Larger vehicles typically present a more substantial surface area for the radar waves to detect, making it easier for the equipment to lock onto them and determine their speed accurately. This principle is particularly important in scenarios with multiple vehicles, where smaller or similarly sized vehicles may not reflect the radar signal as efficiently, leading to potential misidentification of speed.

Vehicles like trucks or larger SUVs will often have a prominent return signal, thereby increasing the likelihood that the radar will capture their speed compared to smaller cars or motorcycles that may be in the same range. Radar systems are designed to prioritize signals based on size and profile, which is why the vehicle with the largest profile is more likely to be detected.
