What is the name of your state (only U.S. law)? Pennsylvania. I had a question about ignition interlock. I was convicted of my second dui in 2006. It states in the law for a second time dui offender he/she has to install a approved ignition interlock for one year. My year is up and my regular drivers license is in my possesion. I want to have my ignition interlock removed but because I had one (ignition interlock) break in my possesion they informed me that I have to pay for it before I can have it removed. My question is if the law states one year and I completed the year can they legally refuse to remove the ignition interlock?What is the name of your state (only U.S. law)?
