The driver blows into the device, and if their breath alcohol content is below the programmed limit, the car will start. You’ll also have to complete periodic retests after starting your vehicle to ensure continued compliance. Learn more about how IIDs work with our complete guide.

Excellent TrustScore Rating
#1 Customer Rated 4.7 out of 5

"Honestly I was bitter at first. But that was because of my own issues with it being mandatory. Other than watching the price rise dramatically, I think smart start is a thorough company that truly separates drinking from driving.I think every car on the road should have one. I recently had one reinstalled into my new truck to do the final 4 months. Shauna was excellent. I was able to get it installed the same day. She was intelligent and professional and went the extra mile to make sure I was content and even gave me a break on something that im sure she didn't have to. Once I settled in and grew up, the company grew on me and I was able to see it for more than the nuisance it had began with."
