The mirrors are of no use when going into other lanes, you cannot see other vehicles coming because the mirrors are too small. They do not have the other small mirror there where you can see other surroundings, just plain small mirrors, and other people I have talked to have had the same problem with their mirrors. I will have to buy other mirrors to put on my truck just to be safe, and not wreck - so I hope I have helped someone not to have same problem I have had.
