There are exactly 2 blind spots on trucks. Directly in front of the hood, and directly behind the trailer. Anywhere else, the driver can see either in his mirrors, or by turning his head. The whole "blind spots on the side of trucks" thing is BS. If you're a truck driver and you believe it, try moving your head forward or backwards while looking in the mirror, you will be able to see 100% of the lanes next to your truck.

That said, there are WAY too many truck drivers out there that have no business being behind the wheel of a hot wheels car, never mind an 80,000# truck.
