How long do I have to keep my interlock device?
We hear this question a lot from our interlock customers: “How long do I have to keep my interlock device installed?”
That depends on many things including state and local laws in place when you are ordered to get an interlock device. Other factors play a part as well. But no matter where you live in Louisiana, we’ve got a location near you for quick and easy ignition interlock installation.
We’re the experts in interlock state regulations
Studies have shown that ignition interlock devices make the roads safer by preventing a vehicle from starting if there is an unlawful amount of alcohol on a driver’s breath. Because of how effective they are, all 50 states have laws on the books regarding the use of ignition interlock devices.
There are a number of factors that impact how long you will have to keep your ignition interlock device installed. But they vary a lot state-by-state, so it’s important to clearly understand the laws and requirements from the beginning of your monitoring.
Louisiana interlock laws
If you have been convicted of driving while intoxicated in Louisiana, your driver’s license is subject to suspension under the law.
Additional information is available on our Laws page.
Number of DUI offenses may be a consideration
The length of time you have to keep your ignition interlock device installed is typically correlated with the number of DUI offenses you have. Your length of time will often become progressively more harsh with ignition interlock device requirements after the first offense.
Alcohol levels also make a difference
Higher BAC levels typically require harsher penalties. When your blood alcohol content is “much more” than the legal limit, your penalties can be “much more” than standard penalties. If a first time DUI offender in Louisiana has a blood alcohol level of 0.15 or higher, they are subject to more severe penalties. There is another increase in penalties for a level of 0.20 or higher.
Judicial discretion and other factors
In some jurisdictions, judges or legal authorities have discretion regarding DUI penalties. This might include things like fines, classes, rehabilitation programs, community service, and the use of ignition interlock devices.
Judges may consider:
- Impact on any victims such as death or injury
- Previous DUI offenses or other criminal history
- Other factors such as whether children were present in the vehicle
Another potential problem may arise if you don’t adhere to the terms of your probation or monitoring. Violations can sometimes result in an extended requirement for ignition interlock. You’ll always want to work closely with your attorney or monitoring authorities in your jurisdiction.
“It depends.”
