Blind spots

This is why I get freaked out when I am driving around SMI trucks

Theres a lot of blind spots

Then where CAN he see them?

Also, the ones that carry rolls of steel to automotive factories can weigh up to 100,000 pounds.

Why isn't there one on top? thats a major blind spot

Good rule of thumb no matter what you're driving/riding, if it's bigger than you, it has the right of way.
Remember that if you can't see a mirror or the driver's head, you can't be seen.

Should probably adjust his mirrors then ;)
