New Study Shows Benefits of Ignition Interlock Devices

Charlotte Criminal Lawyer Brad Smith answers the question: “Why is it important to hire a DWI lawyer quickly after being charged with a DWI?”


In North Carolina, some drivers who have been convicted of driving while impaired are required to have an ignition interlock device (IID) installed in their car. The idea behind this is that in order to start the vehicle and continue driving, the driver can not be impaired. We live in a society in which driving is almost always necessary. The device gives drivers who have lost their license the ability to regain their license with just some conditions. Not every driver who is convicted of an impairment-related charge will be required to have an ignition interlock system in his or her vehicle. It depends on the specific state laws and the circumstances surrounding the charge and conviction. The device can be an excellent way for the defendant to retain possession of his or her license.


Car-ignition-interlock-Charlotte-Monroe-Lake-Norman-DWI-Lawyer-300x237A new study conducted by the National Center for State Courts explores the safety benefits of ignition interlock systems. Not all states have the same ignition interlock system laws. Some states are stringent in their requirements, while others are not. There is a vast difference in the percentages of alcohol-related crashes for states that require every person convicted of impaired driving to have an ignition interlock device and states that do not. In North Carolina, there is a small section of people convicted who are required to have an ignition interlock device installed. States with more stringent ignition interlock system laws might see up to 15% fewer alcohol-related crash deaths.


Ignition Interlock Systems in North Carolina

North Carolina is one of the states that has less stringent rules about ignition interlock systems than other states. These are the groups of people who might be subject to having an ignition interlock system in their vehicle:


  • A person convicted of driving while impaired with a blood alcohol concentration of 0.15 or more
  • A person convicted two or more times within seven years of the current offense that leads to the license being revoked
  • A person convicted of aggravated DUI at level one


A driver with a blood alcohol concentration of 0.15 or more must have an ignition interlock system installed in his or her vehicle. It is up to the judge to determine what the sentence will be for those who are convicted of DWI with a lower blood alcohol content.


As you can see, there are limited situations in which a person is required to have an ignition interlock system. While having the system in your car may seem inconvenient, it is actually a way for the defendant to regain possession of his or her license, albeit with a few conditions.
