Few drivers fully understand the impact of a DUI conviction. Not only will offenders face jail time and a possible prison sentence, but the financial impact could be devastating: first-time offenders are responsible for an average of $10,828 in out-of-pocket expenses.

On top of that, car insurance rates skyrocket following a DUI conviction. Mothers Against Drunk Driving (MADD), a non-profit organization dedicated to sober driving, reports that a first-time DUI offender can expect their car insurance rates to range between $3,600 and $6,600 a year.

Depending on how long a DUI conviction remains on your driving record, these astronomical car insurance rates can continue for up to seven years. Furthermore, if any accidents and tickets (past or future) are on your record, your car insurance rate could triple. And in this economy, a pricey car insurance rate is the last thing you need.

Some cities are offering unique ways to combat intoxicated driving on St. Patrick's Day. In and around Washington D.C., the St. Patty's Day SoberRide program provides free cab rides to citizens of the nation's capital. Residents can dial 800-200-TAXI to take advantage of this service. Over 200 people used the service last year.

If you're planning on hitting the town this St. Patty's Day, keep the streets safe by drinking responsibly and bringing along a designated driver.
