When a driver is traveling slower than the normal speed, it is essential for safety and efficiency on the road to allow traffic to pass when it's safe to do so. This is particularly important on highways or multi-lane roads, where maintaining a steady flow of traffic is crucial.

Allowing traffic to pass at the earliest safer opportunity helps to prevent disruptions and reduces the likelihood of frustration among other drivers. It promotes a smoother traffic flow, which is beneficial for everyone on the road.

The options of ignoring traffic, switching lanes frequently, or pulling over to stop can lead to dangerous situations. Ignoring traffic disregards the safety of others and could provoke aggressive driving behavior. Switching lanes frequently can create confusion and increase the odds of a collision. Pulling over and stopping may not be safe or practical unless absolutely necessary, as it can also impede traffic.

Thus, the best approach is for the driver to facilitate the safe passage of others while maintaining their own safety and the overall flow of traffic.
