Driving: "Opaque" Vehicles

By this, I mean vehicles you can't see through, around, or over. For those in a car or on a motorcycle (or bicycle, but this page is intended for motor vehicles), this usually means such things as vans, SUVs, pickups, bigger trucks... and cars with tinted windows. If you are driving a tall vehicle, you may be able to see over or through some of these, so for you they don't count as such. You get the idea....
