You will face certain Nebraska drunk driving penalties if you are caught driving under the influence of alcohol with a BAC level of 0.08 or more (for commercial drivers, the BAC limit is 0.14; for under-21 drivers, it is 0.02). It is important to note that when you are stopped under the suspicion of drunk driving, you must not refuse to take the chemical test to determine the BAC level. If you refuse, that will attract immediate penalties; for a first time refusal, your driving license will be suspended for twelve months. This penalty is mandatory and you will have to face it even if all the charges against you get dismissed in the court. Following is a brief rundown on what type of penalties you can expect when you get convicted.
