Yes. If you must drive an employer-owned vehicle for work there is an exemption that allows you to drive that employer-owned vehicle. However, you still must install the IID on your personal vehicle. Also, your employer must fill-out the exemption form.
See link: IID Exemption (employer)
The Form States:
"To be eligible for an employer exemption, you must have an IID installed in your personal vehicle. In addition, there is a wait period during which time you may not drive an employer owned vehicle without an IID. This wait period is a specific number of days (below) from the date your suspension/revocation began as a result of the conviction, or date the IID was installed, whichever is later:
•
First alcohol/drug conviction – 30 days
•
Second or subsequent alcohol/drug conviction – 365 days"
