How long should an emblem for a slow-moving vehicle be displayed?

The display of an emblem for a slow-moving vehicle should occur while the vehicle is in operation. This is important because the emblem serves as a warning to other drivers that the vehicle is moving slower than the typical speed limit, which is crucial for maintaining safety on the road. When the emblem is displayed, it alerts other motorists to be cautious and provides them with the necessary information to adjust their driving accordingly.

In instances where the vehicle is not in motion, such as parked or stationary, the emblem is not needed, as it does not pose a potential hazard to other drivers. Therefore, it is essential that the emblem be used only when the vehicle is actively being operated on public roads, ensuring that safety is prioritized at all times. This practice helps prevent accidents and misunderstandings between vehicles of varying speeds.
