New DUI laws, effective January, 2011, have substantially increased the punishment for drivers under the influence. The existing DUI laws, along with the new additions, are outlined below.
Ignition Interlock Device
One new addition to the DUI law is the ignition interlock device. For DUI offenders whose blood alcohol content registers higher than .15 percent or for BAC under .08, if the offender has a passenger under the age of 18 at the time of the offense, ignition interlock devices will be required for DUI offenses wherein an accident resulting in injury or property damage over $400. The device will also be required for offenders who refuse to take a breath or blood test upon their arrest of DUI.
