With a lot of revelery expected this weekend for the St. Patrick’s Day holiday, D.C. Police officials are recommending that partiers find a sober designated driver, use public transportation, call a friend or family member, or use the Washington Regional Alcohol Program’s SoberRide service.

From 6 p.m. Saturday to 6 a.m. Sunday, SoberRide will provide free service (up to a $30 fare) to residents of the District, and neighboring suburban counties.

Over 50,000 free rides have been provided since SoberRide began this service almost 30 years ago. Call 1-800-200-TAXI. For more information, visit www.soberride.com.

The majority of drunken driving arrests occur with first-time offenders, according to the Metropolitan Police Department (MPD). Police say many of those who were arrested said they felt fine before getting behind the wheel.

According to the MPD website:

-The legal limit for Blood Alcohol Content (BAC) in the District of Columbia is .08 percent. Furthermore, if the driver is under 21 and has any measurable alcohol levels, (s)he will be arrested.

-You could be arrested and convicted for Driving Under the Influence (DUI) at a level lower than the legal limit. You may be arrested if, in addition to a BAC reading, an officer finds other signs of impairment from a structured field sobriety test and from observations of the suspect’s driving behavior.

-Your Blood Alcohol Content could continue to rise, even after you have stopped drinking. If you have had several drinks in a short time frame, your BAC could actually rise, even after you have stopped drinking, because of the slow rate at which the body eliminates alcohol.

-The consequences if you are arrested and convicted for a first-time drunk driving offense include up to 90 days in jail, six months license revocation, sky-rocketing insurance rates and thousands of dollars in fines.
