All this arguing..
Heres the plain truth. Your company.. any company heres of you having a beeer in the cab of your truck you're out of trucking. Done. Finished.
A trooper or DOT officer finds one he's gonna take you, your log books and your truck apart and maybe call your company.
I knew a guy who was like some of these guys.. they HAD to have alchohol. though they deny it.. they just "toss down a couple soldiers".. which btw is what my VERY alchoholic grandfather called them. This one drank a quart of vodka every night before bed. He ran about 300 miles a day and lived in his truck. The vodka is all he had. He was suffering from late term alchoholism (swollen nose cartilidge from liver failure) and he complained that he constantly got pulled in by dot. Thing is he got pulled a couple times legit, they saw the signs and put the word out.
If you cant give up alchohol (at least except at home) give up trucking. Its not a moral thing it s a law thing.
Now.. imagine a car slams on the brakes in front of you. You kill them.. their fault. Well.. cept you had 6 beers the night before and are still blowing a .02. Your great great great great grandchildren will still be paying off the judgement against you. Even if you do get off the vehicular homicide charge.
