No you don’t. Over 50% of crashes are single car accidents. I suspect, but don’t have proof for, that that percentage is even higher in alcohol-related crashes (eg driver nods off and drives into a ditch/telephone pole
How? The 26.8% is just drivers with alcohol in their system. If I never drink and drive, I will never be part of that group. That means the raw rate of traffic fatality or severe injury is 26.8% lower for people like me (non drunk drivers.)
