identifying a first external cause and a second external cause;
based on the analysis of the first vehicle driving data associated with the occurrence of sudden braking, swerving, or impact by the first vehicle, determining a percentage of cause associated with each of the first external cause and the second external cause;
evaluating the determined percentage of cause of the first external cause and the second external cause to identify one of the first external cause and the second external cause as a primary cause, the primary cause being the cause having a percentage greater than a predetermined event cause threshold;
determining whether the primary cause was unsafe or high-risk driving;
responsive to determining that the primary cause was unsafe or high-risk driving, adjusting the driver score;
responsive to determining that the primary cause was not unsafe or high-risk driving, maintaining the driver score based on the occurrence of sudden braking, swerving or impact by the first vehicle; and
if at least two external causes cannot be identified, determining that high-risk or unsafe driving by the driver of the first vehicle was the cause of the occurrence of sudden braking, swerving, or impact by the first vehicle and adjusting the driver score based on the at least two external causes not being identified.

Abstract
A driving analysis server may be configured to receive vehicle operation data from vehicle sensors, and may use the data to identify a potentially high-risk or unsafe driving event by the vehicle. The driving analysis server also may receive corresponding image data, video, or object proximity data from the vehicle or one or more other data sources, and may use the image, video, or proximity data to analyze the potentially high-risk or unsafe driving event. A driver score for the vehicle or driver may be calculated or adjusted based on the analysis of the data and the determination of one or more causes of the driving event.
