You can actually drive a collector plate vehicle to and from work... you just don't qualify for any discount and pay regular insurance with a fancy plate

edit: Apparently I was wrong to assume the work thing as per Mr. Edison below
From ICBC:
Reduced collector vehicle insurance premiums
Your collector vehicle may qualify for reduced collector insurance premium if you:
Own or lease another non-collector vehicle registered and licensed in your name, or
Have a company-assigned vehicle used for general transportation and insured under one of the applicable rate classes (see For Insurance Purposes in the Application for Collector Vehicle Status).
If the only vehicle you have is your collector vehicle, it may still qualify for collector plates. However, it won't qualify for reduced collector vehicle insurance premium.
