The clearest image of moving cars will be produced using the 1/500 second shutter speed.
Shutter speeds control how long the camera's sensor is exposed to light, and faster shutter speeds (like 1/500 second) can freeze motion, reducing blur caused by moving subjects. Slower shutter speeds (like 1/8 or 1/2 second) will likely result in blurred images when capturing fast-moving objects like cars. Therefore, to achieve the clearest image, the 1/500 second shutter speed is the best option.
