Why do tractor trailer trucks constantly drive in the left lanes on highways?

Question

And no there is not a left exit. It really causes a traffic backup and they keep trying to pass each other basically blocking the lanes?

Answer 1

smooth lane

drafting

Answer 2

i'm trucker myself, so here it is. Usually its safer 2 drive in left lane if u see exits coming up. Due 2 size of semi (23metres) sometimes its impossible 2 change lane 2 let somebody on freeway, in same time due 2 weight (80000lbs) impossible 2 brake accordingly in case any trouble. Sorry if it bothers u. but it even more bothers me when cars jumping on freeway under my nose risking their life and my future

Answer 3

CONSTANTLY ?   humnn,,,   so we don't have to worry about 4-wheelers trying to merge on/off while talking on cell phones,,, or deal with poorly designed ramps that invite accidents as drivers scramble for space,,,or drive over you since you insist on driving slower for safety's sake...

Answer 4

yea I know some times one truck might be governed 1 or 2 mph faster and it seams to take forever but as long as they are running the minimum speed there's not much to do but wait but there are a lot of 4-wheelers that do the same thing. command curiosity is a thing of the past expressly with the younger generation.

Answer 5

For the most part the left lane is much smoother.

Answer 6

It is safer to a point because they will not have to worry about changing lanes and running over someone but at the same time it is illegal for these trucks to travel in the left lanes in many states.
