Duties of experts

In England and Wales, under the Civil Procedure Rules 1998 (CPR), an expert witness is required to be independent and address his or her expert report to the court. A witness may be jointly instructed by both sides if the parties agree to this, especially in cases where the liability is relatively small.

Under the CPR, expert witnesses are usually instructed to produce a joint statement detailing points of agreement and disagreement to assist the court or tribunal. The meeting is held quite independently of instructing lawyers, and often assists in resolution of a case, especially if the experts review and modify their opinions. When this happens, substantial trial costs can be saved when the parties to a dispute agree to a settlement. In most systems, the trial (or the procedure) can be suspended in order to allow the experts to study the case and produce their results. More frequently, meetings of experts occur before trial.



Blood alcohol content

Blood alcohol content (BAC), also called blood alcohol concentration, blood ethanol concentration, or blood alcohol level is most commonly used as a metric of alcohol intoxication for legal or medical purposes.

Blood alcohol content is usually expressed as a percentage of alcohol in the blood. For instance, a BAC of 0.10 means that 0.10% (one tenth of one percent) of a person's blood, by volume (usually, but in some countries by mass), is alcohol.



Vehicle operation

A BAC of =0.080 or more is considered "legally intoxicated" for driving in most American states. Likewise, =0.050 is considered NOT impaired in most states. In the State of Washington a driver can get charged with DUI (Revised Code of Washington 46.61.502 - Driving Under The Influence of Alcohol/Drugs) even if the person's BAC is under .08. The charge of DUI for anything under the .08 BAC threshold is based on whether or not the driver's ability to safely operate a motor vehicle is affected by alcohol, drugs or any combination thereof.[9]
