Under what circumstance do traffic laws apply to workers on the freeway?

The correct context for understanding the application of traffic laws to workers on the freeway is that they are always applicable. Traffic laws are in effect at all times on public roadways, which includes freeways. This means that individuals, including workers, must follow the same set of traffic regulations regardless of their activities, whether they are driving for work, on break, or involved in any other task. The reality is that traffic laws do not change based on the time of day or specific circumstances of employment; they are universally applicable.

It's important to understand that while workers may be commuting to or from their place of employment, they are still subject to the same laws as any other driver on the road. Consequently, safety regulations, speed limits, and other traffic laws apply at all times to ensure the safety of everyone on the roadway.
