What is a key factor to determine fault in vehicle collisions?

Determining fault in vehicle collisions largely hinges on how well the parties involved adhere to established traffic laws. Traffic regulations are designed to create a safe environment for all road users and dictate the expected behaviors of drivers, such as stopping at red lights, yielding the right of way, and maintaining safe driving speeds. When an accident occurs, investigating whether one or more parties violated these laws can provide clear evidence pointing to negligence or responsibility for the resulting collision.

Other factors, like the type of vehicle, weather conditions, or the presence of traffic signals, can contribute context or influence the circumstances of an accident but do not fundamentally determine fault. For instance, while the weather can affect driving conditions, and the presence of a traffic signal indicates rules that should be followed, these elements alone cannot adequately assess responsibility without contextualizing them within the framework of traffic law adherence.
