When it comes down to impaired driving, the definition to me is relatively concrete, with it meaning your ability to drive safely has been compromised, or in other words, impaired, which in turn makes an impaired driver a danger on the road to themself and other drivers. This can sometimes be misunderstood for thinking impaired means you can not drive period, such as a severe injury or inability to do things that are necessary to drive. That definition is not terrible by any means, but it is not what being an impaired driver is either. Being impaired whilst driving is one of the largest issues we have as of today in the world of the roads and highways, for driving is how just about everyone gets around to just about anywhere in their area, meaning safety regarding driving should be the largest concern, yet there are still sadly many, many deaths or severe injuries involving driving accidents.
Being impaired is most commonly found from alcohol, fatigue, and texting, all of which should be no brainers when it comes to not driving while doing any of those things. And even with the mountains of risks that come with driving while being impaired in any way, shape, or form, people still tend to do so anyway for various reasons. With the three most common ones that I said affecting each and every driver somewhat similarly, and of course, all of them being avoidable. First and foremost being alcohol consumption, or being drunk while driving. Drunk driving is the most heavily enforced version of being illegal everywhere in terms of impaired driving, with the affects from alcohol only getting exponentially worse the more of it you have had. The most common effects being lessened vision, or tunnel vision, drowsiness, increased recklessness, and the inability to think clearly coherently if said driver has had far too much to drink before hopping into their car. Fatigue is the second method that is also very common, and it shares some effects with alcohol, with those being drowsiness and lessened attentiveness. Along with that comes texting while driving, which is slowly becoming more and more common, which is nowhere near good, but as for the effects it has, it takes your focus away completely from driving, meaning you have less control of the car, you could swerve without knowing, and you are not looking where you are going because all of your attention becomes absorbed by the phone, which is why it has caused so, so many incidents. All three of those end up contributing quite a lot to unsafe behavior amongst drivers due to how with even how dangerous it all is, so many people seemingly forget to care about the risks and some sadly end up paying very, very dearly for it.
As for me, I have been extremely lucky to have not personally experienced any incidents stemming from an impaired driver getting me, or anyone I know of into an accident. But I have absolutely heard of a few stories here and there, but I do not remember them very well. Though that does not mean my perception of impaired driving or the way I act behind the wheel. For when it comes to me, I take my time and ensure I do not take any risks, purely out of safety for myself, and especially for anyone else in the car if it is not just me. I know how dangerous the roads truly are, and just how unpredictable they can be, so being an actual defensive driver and playing my cards right for everyone's safety at least makes me feel like I have some semblance of control in those situations.
In a world filled with danger and relatively unchangeable factors, the best way to prepare newer drivers within driving school, etc is to not only show them exactly what happens when somebody drives while impaired with the countless videos out there of survivors of experiences from them to explain how it went down and why they would never do so again. But that will not always work forever, because nobody can predict what could happen in the future, which is exactly why, just like the driving school I went to, always prepare the newer generations of drivers to play defensively and to not take risks, because any singular way to lower your chances of an accident should be taken. What makes them truly effective though, is getting through to their students through experience on the road with practice on safe, defensive driving is so that they can properly build the skills and memory needed to utilize those skills now, and more importantly, in the future. And especially to remind them that if they are tired, etc, to not drive to not endanger themselves or anyone else.
As for me, my best role to prevent impaired driving is to be a good friend and peer, and if someone I know is about to make that mistake of driving while being impaired from any source, to not let them drive for the safety of everyone, especially for their safety, and of course, to be a safe driver myself, because even if only one safe driver is not a lot, it is still a small step forward. It is not always about the most grand things, but sometimes, even the smaller bits can make a large difference over time.
Overall, impaired driving will most likely be a giant issue for decades to come, but that does not mean we should stop our efforts to making the roads even a little safer, because with time, hopefully we can slowly bringing the extensive amount of deaths due to car accidents down even a little at a time.
