You can be cited for not being able to maintain control of your vehicle (being tired, emotionally distraught etc.)
I live in a state that contributes to more than 10% of the DUI or DWI deaths.
In this state, it can not be more of a clear message that if you operate any motor vehicle on a public hi way or road; and are caught, you will 1) be subject to an FST or be arrested for suspicion of DWI, 2) lose your license(s) for a period no less than six months, 3) spend 24-36 hours in our fine incarceration system, 4) and if found guilty, that is after paying an attorney to represent you, pay restitution to the State (about $6000.00), 5) attend AA classes, 6) the final straw; deal with our insurance companies to obtain an SR 21 to become insurable again.
Pretty clear as to what not to do here. Similar in your states?
Why put yourself in this situation to begin with, it's what you'd be asking yourself after this type of ordeal
I'd much rather spend my $14k or so on racing another year
