Don\u2019t push your luck this St. Patrick\u2019s Day. While the holiday may be a time to celebrate with family and friends, your plans should also include transportation to and from your destination if you plan to drink. Law enforcement officials from around the nation will be setting up sobriety checkpoints this evening focusing on both drug and alcohol-impaired drivers. Use this calculator to estimate just how little alcohol it takes to put you on the wrong side of the law. However,\u00a0know that even small amounts of alcohol can affect your ability to drive, so the only safe advice is to avoid any alcohol if you are driving. The National Highway Traffic Safety Administrationreports that two of five\u00a0people killed nationwide in crashes involved a drunk driver during St. Patrick\u2019s Day between 2006 and 2010. NHTSA analyses show alcohol-impaired crashes claimed a life every 53 minutes in 2011. So whether\u00a0your plans include attending a local parade or festival, hosting a party or gathering with friends at the local bar or pub, NHTSA urges everyone to designate a sober driver before alcohol is consumed. The agency also offers the following safety tips: \tDesignate your sober driver\u00a0or have an alternate transportation plan before the party begins. \tIf you don't have a\u00a0designated driver, ask a sober friend for a ride home; call a cab, friend,\u00a0or family member to come and get you; or just stay where you are and don't\u00a0drive until you are sober. \tUse your community's sober ride program. \tNever let a friend drive\u00a0drunk. Arrange a safe way for them to get home. \tDon't ride in a vehicle with\u00a0a driver who is intoxicated. \tAlways buckle up. It's still\u00a0your best defense against drunk drivers. If you are hosting a party: \tMake sure all of your guests designate their sober drivers in advance, or help arrange alternate transportation. \tServe plenty of food and\u00a0non-alcoholic beverages at the party. \tStop serving alcohol a few hours before the end of the party and begin serving coffee and dessert. \tKeep the phone number of local cab companies on hand, and take the keys away from anyone who is thinking of driving drunk and get them a cab ride home. \tRemember, you can be held liable and prosecuted if someone you served ends up in a drunk-driving\u00a0crash. \tIf an underage person drinks and drives, parents may be held liable for any damage, injury or death\u00a0caused by the underage driver. \tLikewise, parents or other\u00a0adults who provide alcohol to, or host a party where alcohol is available\u00a0to, those under age 21 could face jail time.
