What must be shown under the May Have Contributed section of the CR-3?

The May Have Contributed section of the CR-3 form is intended to identify factors that may have played a role in the traffic incident. This can include relevant details such as impaired driving due to alcohol consumption. When 'Had been Drinking' is indicated, it suggests that alcohol may have influenced the driver's ability to operate the vehicle safely, making it a significant contributing factor to the incident. This information is crucial for authorities to analyze the cause of the accident and helps in enforcing traffic safety measures by identifying patterns related to alcohol-related incidents.

In contrast, while factors such as weather conditions, traffic control devices, and road surface materials can all impact road safety, they do not specifically address the behavior and choices of the driver, which are directly related to the risk of drinking and driving. Hence, the drinking status of the driver is more directly relevant in this context.
