What are the No Zones around large trucks?

Big blind spots where the truck driver cannot see you.

  1. Blind spots where the truck driver cannot see you ✔
  2. Areas where trucks can stop quickly
  3. Truck loading zones

Why: Large trucks have big blind spots in front, beside and behind them. If you cannot see the truck's side mirrors, the truck driver cannot see you.

Huh, didn't know that: A truck with a long hood can have a blind spot of 20 feet right in front of it.

The dad joke
Why do trucks have such big mirrors? So they can see all the cars hiding in their No Zones!
