The only point I would like to add to everything that has been made is regardless of how severe or how extensive the licence suspension is, if it is not supported by law enforcement, in other words RIDE programs, and significant enforcement, the risk of being apprehended will still remain low, and in the minds of people who would be tempted to drive at the range close to 0.05, that will not be a deterrence to them.
The study that mentioned Australia, when it analyzed what works and what reduces the incidence of drinking and driving...the perception drivers have that if they are taking the wheel while they are under the influence of alcohol is high. As long as the general public thinks, “I can take a chance, there are not a whole lot of RIDE operations, I'll take my chances”—as long as that mentality and that attitude lasts, you can have the best administrative licence suspension in the world, it's not going to make a difference.
