| Blood Alcohol CalculatorTo provide an estimate of the number of drinks that it would take a person to become impaired with a BAC of .08 or higher, please check out this Blood Alcohol Calculator on the PA DUI Association Website. The tool asks for the number and type of drinks consumed over what time period, as well as a person´s gender and weight. Please note that this is only an estimate and that a person´s actual BAC can be dependent on numerous other factors. Cost of a DUIThe costs associated with an impaired driving arrest can vary greatly depending on several factors, including blood-alcohol content, location of arrest, and number of offenses. The effect on a driver´s wallet starts the moment they are stopped by police. Here are a few expenses associated with a DUI.
Underage DUI – Zero Tolerance![]() Pennsylvania´s Zero Tolerance Law carries serious consequences for those under 21 who are convicted of driving with any amount of alcohol in their blood. For example, those under 21 who are convicted of driving under the influence with a .02 blood alcohol content, or greater, face severe penalties, including a 12-to-18-month license suspension, 48 hours to six months in jail, and fines from $500 to $5,000. A vehicle does not have to be involved in order for those under 21 to lose their driving privileges. It is against the law for an individual under the age of 21 to consume, possesses or transport alcohol, or lie about their age to obtain alcohol and carry a fake identification card. If convicted, the minimum penalties are a fine of up to $500, plus court costs; a 90-day license suspension for the first offense; a 1-year suspension for the second offense; and a 2-year suspension for the third and subsequent offenses. Impaired Driving Enforcement in Pennsylvania![]() Although alcohol-related fatalities account for more than 30 percent of all traffic fatalities in Pennsylvania, impaired driving enforcement covers more than just alcohol impairment. Law enforcement also works to identify motorists impaired by drugs and prescription medication, or some combination of these. Ignition Interlock Law![]() In Pennsylvania, any person convicted of a second or subsequent offense of DUI is required to have an ignition interlock system installed on their vehicle for one year. These devices work by requiring the driver to blow into it before starting the vehicle. If the device detects alcohol, it will prevent the vehicle from starting. Ignition interlock devices will also prompt the driver to blow into the device at period times during the operation of the vehicle. |
