how long do you have to blow into an interlock

An ignition interlock device (IID), often called an "interlock," requires you to provide a breath sample before starting your vehicle. But how long do you have to endure this process? The answer isn't simple, as it depends on several factors. This article will break down the duration of your interlock requirement and related considerations.

Understanding Your Ignition Interlock Restriction

The length of time you're required to use an interlock is determined primarily by your state's laws and the specifics of your DUI or DWI conviction. Generally, the minimum duration is six months, but it can extend to several years, even exceeding two years in some jurisdictions. Your sentence will detail the exact timeframe mandated by the court.

Factors Affecting Interlock Duration:

State Laws: Each state has its own regulations concerning IIDs. Some states impose mandatory minimums, while others allow for variations based on the severity of the offense and the individual's circumstances. Always refer to your state's specific DUI laws.
Number of Offenses: Repeat DUI offenders typically face longer interlock requirements. A second or subsequent offense will significantly increase the mandated duration.
Blood Alcohol Content (BAC): A higher BAC at the time of arrest often translates to a longer interlock period. This reflects the severity of the impairment.
Refusal to Test: Refusing a chemical test (blood, breath, or urine) during a DUI stop can result in harsher penalties, including a more extended interlock requirement.
Completion of Other Requirements: Successfully completing other aspects of your sentence, like alcohol education programs or community service, might not directly reduce the interlock duration. However, showing good faith cooperation can influence future judicial decisions.

The Daily Routine with an Interlock Device

While the overall duration is critical, understanding the daily interaction with the device is equally important. Each time you start your vehicle, you'll need to provide a breath sample. The device will test for alcohol and will only allow the vehicle to start if the result is below the pre-set legal limit (usually 0.00% BAC).

How Long Does the Breath Test Take?

The breath test itself is typically quick, lasting only a few seconds. However, the entire start-up process might take a little longer, including:

Device Power-Up: The interlock device might require a few seconds to initialize.
Initial Breath Sample: You'll provide a preliminary breath sample to ensure the device is functioning correctly and to detect any tampering attempts.
Rolling Retests: Many interlocks require random breath tests while driving. These usually involve a short interruption, lasting only a few seconds.

Consequences of Non-Compliance

Failing to comply with the interlock requirements can have serious consequences. These can include:

License Suspension or Revocation: Non-compliance is a direct violation of your court-ordered sentence. The result can be a suspension or even revocation of your driving privileges.
Jail Time: In some cases, non-compliance can lead to additional jail time.
Increased Fines: Expect significant fines for violating the terms of your interlock requirement.

Maintaining Your Interlock

Proper maintenance and calibration are essential. Regularly scheduled service visits are typically required to maintain the interlock's functionality. Missing these appointments can result in further penalties.

Remember: The duration of your interlock requirement is a serious matter. Consult with your legal counsel and the court to understand the specifics of your sentence. Ignoring the terms can lead to severe legal repercussions. Always comply with all aspects of your court order to regain your driving privileges and move forward.
