Whenever I am on the highway and heading for a destination in the middle of the day it never fails there seems to be a tractor-trailer with a smaller truck in front and in back to guide the tractor-trailer on the road because he is carrying a "wide load".
They are usually heading for a construction site and the tractor-trailer needs assistance with the guided trip so no one following him will get hurt.
They also watch in case anything from the truck falls off or if one of the ropes or chains comes loose.
Another time you may see a tractor-trailer carrying a wide load is if they have just come from a wooded track of land and have just cut down some timber.
The tractor-trailer would be carrying the timber logs on the highway.
Could you imagine if one of the ropes or chains came loose on that rig? What a horrible accident that could cause if anyone was driving next to or very close by to the tractor-trailer.
This would be an example of why you would not want to follow someone closely in a tractor-trailer.
These loads sometimes can be unstable and no matter how tightly they have tried to restrain it things can always happen while driving on the road.
Think back when you were taking driving lessons so you could get a discount on your auto insurance rates.
The instructor would instruct you on how far to stay away from the driver in front of you.
This is considered safe driver and should still be something that you do on the road.
If you are ever curious about what the insurance rates cost for an eighteen wheeler you could look them up on the internet and search for auto insurance quotes to see the difference in price because of the additional axles the tractor-trailer has compared to a car.
Try to remember that the next time you are on the road and you see a small or large convoy to allow them the room they are asking for even though it is a quiet request.
