Which of the following is a quality of a good collision investigator?

A good collision investigator exhibits courtesy as it is essential in managing the delicate nature of accident scenes. Being courteous helps in effectively communicating with victims, witnesses, and other first responders. This quality fosters a cooperative environment, making it easier to gather accurate information and details surrounding the incident. It also reflects professionalism, which is vital when dealing with sensitive situations that may involve injury or loss of life.

The other qualities mentioned do not align with the necessary attributes of a successful investigator. Being indecisive would hinder effective decision-making, particularly when quick judgments are necessary to assess the scene and formulate conclusions. A desire to take risks would compromise safety and thoroughness, which are crucial in an investigative setting. Remaining uninformed about traffic laws would severely impair an investigator's ability to analyze an accident accurately, as knowledge of these laws is fundamental to understanding the circumstances of a collision. Overall, courtesy stands out as a foundational quality that enhances communication, rapport, and the overall effectiveness of a collision investigator.
