Legal Question in DUI Law in Virginia

Re: dui law 46.2-341.4

This is a list of statutory definitions applying to commercial drivers and vehicles. Although it does not seem to include any reference

to the interlock system which you've mentioned in your question, if a judge has ordered you to install and utilize an interlock system in your personal vehicle as part of your DUI sentencing disposition, this requirement would also undoubtedly apply to any commercial vehicle which you might regularly operate on the public roads and highways of the Commonwealth.
