Can anyone explain the reason for the passenger mirror above window?

But I will say I didn't realize this was the non experienced thread, so I do apologize..but to the inexperienced learn to back without it because not all trucks have them.and I was not making fun just expressing my opinion.

 

It's fixed on my 2018 Volvo...same as it was on the 2013 I had before.

I may be one of the only members here who use it daily. I pull a fuel tanker. There's several of my accounts that I have to get my passenger side RIGHT AGAINST the curb. I use that mirror along with the hood mirror and bottom convex mirror to position my step parallel and as close to the curb without scraping the tire sidewall as I could possibly get. Those few inches are difference in which hoses I have to drag off the trailer.

 

Same. It has saved my wheels many times over the years and I've been driving for 21 years this March. I don't have fender mirrors but there has been times where it would have been nice to have one. I've even considered removing my door frame mirror after not using it for long periods of time but every now and then it comes in handy no doubt so it stays.

 

I own a pete 379. On don’t have fender mirrors. Like I said, if you don’t use it and the sight of it is bothering you, then get rid of it. So what’s the point of the thread then?

 

Fender mirrors? Nooo!

This thread isn't about fender mirrors or pink tutu's!

 

The mirror above the passenger door is used to check for objects or vehicles next to you in your blind spot.

The upper door mirror was installed there because as trucks evolved, the OEM engineers decided that the peeper fresnal window (some were clear glass) onthe lower passenger door were no longer needed, as most drivers had so much garbage on the passenger floor or had it covered it up for privacy reasons it was no longer viable to keep making it available.

Also alot of thieves used to pop them out from the outside to gain access to the inside door handle to open your truck while you were sleeping, or when your truck was unattended.

The earlier overhead door mirrors that were installed in the late 90's to the mid 2000's on Volvo trucks were adjustable up or down, and some could be rotated 360° around too.

The overhead door mirrors on early Freightliner and PACCAR trucks were only adjustable up or down and later became available in a fixed position only.

When IdleAir was popular back in the mid 2000's alot of drivers removed the overhead door mirror because it interfered with installing the module into the window adapter.

On the later model and present day trucks the OEM's started having them in a fixed position, as a majority of the aero trucks are equipped with OEM hood mirrors now as standard equipment and they are used in conjunction with the overhead door mirror to help see objects around your truck.

 

Mine is adjusted so I can see roughly 4 feet off the right side of the truck. Handy to see if there’s a motorcycle riding in my blind spot where the convex doesn’t see too well. I sure don’t NEED it, but it’s there so why not use it.

 

When they came out we laughed at the fender mirrors. We called them school bus mirrors. The ones above the right window were curb mirrors. Surely for non drivers.
I watched a driver back a long conventional and a 53 foot trailer in a very tight spot without getting out to look. That was blind side! He explained to me he could see if the trailer cleared in the corner of the fender mirror. Then knew he was good, squared off the parking lot set up and or lines, until he caught sight in the left mirror.
When I thought I was pretty good I watched out a hotel window in Boston. The large lot next door was a combination construction sight and parking lot. Driver with a roll off container truck came through there and put a camel through the eye of a needle.
Just saying some people with special skills get a lot of use out of them at times.

 

Some people seem like they were born backing into tight spots.
