I am a semi truck driver. These trucks can be dangerous if you don't know how they work. ie.. they are heavy & therefore it takes lots more time to stop a semi than a automobile. There are "blind spots". "Blind spots" are places like directly in front of us, beside us and behind us that we cannot see even with our mirrors. Other vehicles in these "blind spots" are putting themselves and others at safety risk. Semi trucks also need tons of room to make turns so we make WIDE turns and then we get some other vehicle come up beside us while making this turn and this results in an accident. Drivers of semi trucks must follow Federal Rules that the public is not made aware. The public also does not seem to see the signs on roadsides that say things like "Trucks use 2 right lanes" or in a construction area a sign says "Trucks use left lane only" or the split speed limit for trucks and cars.. ie.. speed limit 65mph trucks 55mph. That split speed causes impatience with drivers of automobiles THE QUESTION IS HOW DO WE INFORM THE PUBLIC REGARDING THIS MATTER
