If I have had a DUI in Virginia, does fr44 insurance allow me to drive a company truck ?

Commercial Rules of the Road – FR44 Insurance in Virginia

The quick answer is No. In Virginia DUI laws are more strict against a driver holding commercial driving license. Under normal circumstances, a driver will be arrested in Virginia if the driver’s Blood Alchohol Content (BAC) is above 0.08%. But in the case of a driver holding commercial driving license, your BAC level should cannot exceed 0.04%.  If you are a driver holding commercial driving license in Virginia, if you are arrested under DUI, your driving license is likely to be suspended up-to, a period of one year.  Having FR44 insurance has got nothing to do with your suspension of your commercial driving license and will not help you under DUI laws of Virginia.
