Driving while intoxicated is a very dicey issue. When I was a pothead I definitely drove better while stoned, that being said many people I know drive much worse while stoned. For fuck's sake one acquaintance of mine randomly started doing donuts in synagogue parking lot and proceeded to take out the neighbors flowerbed. I've driven on almost every standard drug and I'm not proud of it. Nowadays I'm clean as a whistle, and I can tell when someone near me on the road is out of it. Scary thing people driving large SUV's and Tractor Trailers while intoxicated or sleep deprived. Sleep deprivation and driving should receive more attention as it causes many accidents and deaths. I've got my commercial driver's license and have driven Tractor Trailers, there's a heavy drug culture within the over the road trucking industry. Tractor Trailers are the largest things on the road for the most part, generally I would advise keeping safe distance from them on highways and if you have to pass them do it quickly. Obviously don't get boxed in by them, most cars are too small for them to see. Yeah, I'm ranting about safe driving, but as a professional driver it's partially my duty to advise safe driving practices. Don't get fucked up and drive, be smart, if you end up killing someone else on the road you'll be guilt ridden for the rest of your life most likely. (Some assholes don't give a shit, but fuck them) If you die, people will be sad, and you'll be dead and that probably will suck to some degree. So make smart decisions, if you are driving and suddenly feel more fucked up than you expected pull into a public parking lot and wait it out. It's not worth risking your life to try and get where your going. I'm done, don't be stupid, thank you
