Prices are each company's national starting price. The 12-month column adds a year of that price, the install price and any set-up fee, or MADD's typical $70 to $150 where no install price is posted.
MADD's national range: $70 to $150 to install, then $60 to $80 a month, or $790 to $1,110 for a year.

What the court orders
Your court order covers every car you drive, and each one needs a state-approved interlock. Even if part of your sentence or fine is suspended, the judge still has to order the interlock unless they grant an exception.
Every expense is yours: getting the device, having it put in, using it and keeping it working. Idaho's transportation department also flags the requirement on the license or restricted driving paperwork you carry.
Picking a device that qualifies
An Idaho interlock has to have a camera, and the transportation department has to certify it. The manufacturers on the department's list are certified as meeting the federal safety standards from the National Highway Traffic Safety Administration.
The transportation department doesn't install interlocks, and it can't recommend a company or tell you where the nearest install center is. Call us and we'll pass your request to a company that serves Idaho so they can set up your appointment. Your one-year restriction starts when the vendor provides proof of installation.
How the device works
You breathe into the interlock before the car will start. If your breath alcohol reaches .025, the car won't start.
Any time the interlock stops a start, the vendor has to notify the prosecuting authority.
Interlock cost in Idaho
Based on nationwide figures from MADD, getting the device put in typically runs $70 to $150, and then you're looking at $60 to $80 each month. For most people that comes to roughly $790 to $1,110 for a full year on the device.
Prices vary by company, so your quote may be a bit higher or lower than these averages.
Help paying for the device
If money is tight, a judge can approve help from the court's fund for interlock and electronic monitoring devices. That aid covers installing and running the interlock, and it hinges on proof that you're struggling financially.
When the restriction ends
The vendor's proof of installation starts a one-year clock, and the restriction ends when that year runs out. Ask the installer about the proof of installation when your interlock goes in.
