What happens during the phase defined as Day Time?

The phase defined as Day Time is characterized by enhanced visibility due to sunlight. This increased natural light allows drivers to see other vehicles, pedestrians, and traffic signals more clearly, contributing to overall safety on the roads. During this phase, the presence of sunlight reduces the likelihood of accidents caused by poor visibility conditions, which might be more common during nighttime or in adverse weather.

While some traffic signals may function differently during the day and there may be changes in traffic flow, the defining feature of Day Time in this context is the benefit of sunlight, which significantly improves visibility. Thus, option C accurately describes a key aspect of what occurs during this phase.
