What is the main purpose of stopping a truck when signals are unclear?

The main purpose of stopping a truck when signals are unclear is to avoid accidents. In situations where visibility or communication is compromised, taking the precaution of halting operations can prevent collisions and ensure the safety of both personnel and equipment. This practice reinforces the importance of situational awareness and prioritizes safety over efficiency or compliance, as unclear signals may indicate potential hazards or changing conditions. By stopping, truck drivers can assess the situation more thoroughly, ensure they have the proper signals to proceed, and protect themselves and their co-workers from dangerous situations that could result from miscommunication or misinterpretation of signals.
