Can I Accurately Calculate My BAC Without A Machine?

The calculation involved in determining one's blood alcohol content is a highly variable and can fluctuate based on a variety of different factors. Some factors include the amount of food one ate that day, the type of food that was eaten, the amount of food still in one's stomach while consuming alcohol, the time of the first drink, the time of the last drink, the interval between drinks and the partition ratio of ones blood.

What Is The Blood Alcohol Content Level In New Jersey For a DWI?

Blood Alcohol Content is the amount of alcohol that is in your bloodstream, and it is expressed as a percentage. This translates that a .08% BAC would mean the drinker has .08 grams of alcohol for every 100 grams of blood in the bloodstream.

Blood Alcohol Content

.08% is an important number when it comes to drinking and driving. This is because .08% is the minimum “legal limit” of blood alcohol content adopted by all states. The BAC reading is not the only factor, however, because in NJ even without a reading or with a reading below .08% a person can be convicted of DWI in what is commonly referred to as an "observation case". An observation case is where a police officer provides an opinion that the person was impaired by the ingestion of alcohol and that said consumption affected the individuals ability to operate a motor vehicle.

Can I Guess My BAC With Some Accuracy?

We don't recommend it. There are numerous “calculators” and charts on the internet that claim to accurately estimate what one's blood alcohol content is based upon answering certain questions. Due to all of the factors outlined above, relying upon these calculations is dangerous if you intend to use these to decide whether to drive after having consumed alcohol. These charts may take into account one's sex and weight and may provide a range but the penalties for driving while intoxicated are too severe to risk leaving it to chance and a BAC calculator.

So If My BAC Is Under .08 I Cannot Be Charged, Right?

Wrong. While that appears to be the common understanding of the drinking and driving laws in New Jersey it is not always the case. Police officers are granted a high degree of discretion in drinking and driving cases. This means that the police officer will look at the totality of the circumstances surrounding each individual case and be free to reach his own conclusion on whether or not the alcohol in one's system affected one's driving. A police officer may reach his conclusion by assessing the driver's infraction that allowed for the stop, the driver's performance on the standard field sobriety tests, or any other facts evident from interacting with the driver. So, all in all, it is best not to take your chances drinking and driving.
