National Highway Traffic Safety Administration: "NHTSA defines fatal collisions as "alcohol-related" if they believe the driver, a passenger, or non-motorist (such as a pedestrian or pedal cyclist) had a blood alcohol content (BAC) of 0.01% or greater." "NHTSA specifically notes that alcohol-related does not necessarily mean a driver or non-occupant was tested for alcohol and that the term does not indicate a collision or fatality was caused by the presence of alcohol."

Also of note: "On average, about 60% of the BAC values are missing or unknown. To analyze what they believe is the complete data, statisticians simulate BAC information.[7] Drivers with a BAC of 0.10% are 6 to 12 times more likely to get into a fatal crash or injury than drivers with no alcohol."
Would you elaborate on this? I read this as meaning that the statistic includes drunk drivers who were involved in a fatal accident but weren't determined to be at fault for causing the accident. Am I understanding your intent correctly?
Assuming this to be the case, I agree that there should be some additional nuance here. That said, it would also need to take into account whether or not their inebriation prevented them from acting defensively to avoid the accident. I'm not sure how this would be done.
