Truck Mirrors that Fold In: The Benefit of Folding Mirrors

If your truck mirrors do not fold in, you may have difficulty parking in tight docks.

Folding truck mirrors: out and in positions.Mike encountered a really tight docking situation at Domino Sugar in Baltimore, Maryland.

The driver who parked in the dock immediately to Mike’s left found that because of the closeness of their trucks, at first, he could not get out of his!

Even as a fairly thin man, this driver had to wiggle and squirm to get out.

If he had been any larger in frame, he would not have been able to exit — except perhaps through a window, which would have been awkward.

He did not have the kind of tractor with a sleeper door and even if he did, exiting through that might also have been awkward.

Here’s why folding truck mirrors help professional drivers.

The extensions on either side of the illustrated tractors represent their mirrors.

Do you see how close the illustrated mirrors are in the narrowly separated dock?

Can you see how the mirrors might bump against each other when one truck’s door is opened?

The Need for Folding Truck Mirrors

Folding mirror on a truck folded in.Once, when we were at the Greensboro terminal of Mike’s trucking company, he had to back under a trailer that had been parked too close to another trailer.

As it turned out, the tractor under the trailer to his right had folding truck mirrors.

So Mike took the liberty of pushing in the driver side mirror long enough to back under the trailer, connect to it and pull it out so he could move past it.

From the passenger seat, the photo here shows what the set-up look like once he backed under the trailer.

Since Mike was driving a Freightliner Cascadia at the time, he could also have pushed in his passenger side mirror.

But we’ll get to that below…

Two truck mirrors near each other. Both can be folded in. One is folded in.If the driver side mirror on the other truck had been out (fully extended) and Mike had backed in with his passenger side mirror fully extended (as shown), the mirrors would have collided.

Let’s get a handle on what kind of space we’re talking about here.

This is the position used for driving.

You can see the lower edge of the window frame at the bottom of the photo.

Measuring the distance between the edge of the mirror and the side of the truck in its fully extended position -- between 17 and 18 inches.Vicki measured the outside edge of the folding truck mirror in its extended position to the window as a point of reference.

Measuring the distance from the outside edge of the mirror to the passenger side window -- about 17 inches.This close-up shows that the outside edge of the passenger side folding truck mirror was 17 inches from the window.

Measuring the hinge on which the folding mirror swings. Since the mirror fully folds in past the edge of the hinge mechanism, it can be less than four inches from the truck's side.Next, Vicki measured the mirror’s support, where the folding mirror hinges.

It is less than 4 inches wide from the side of the truck.

When the mirror is folded in, the outside edge tucks within this 4 inch distance.

So the distance from the truck’s edge goes from 17 inches to about 4 inches when the mirror is folded in.

Folding Truck Mirrors Conclusion

Parking in tightly spaced docks and backing under trailers parked too closely to each other may be only two of the situations we’re aware of where drivers can utilize folding truck mirrors.

We’ve never heard of drivers needing to fold in their mirrors in order to go through a truck wash because at all of the truck washes we’ve ever been to, the workers wash the mirrors on all sides in their fully extended positions.

Still, the folding aspect comes in very handy at helping you save the cost of a dented or damaged mirror in the situations we’ve mentioned.

Here are the results of a search on for heated mirror, the costs of which range based on the part.

Other fancier truck mirrors may cost more.

Not only will there be the cost of replacing the mirror or frame or both, but there will be down time associated with the repair when a mirror is damaged.

Someone may even have to call a shop to make an on-site repair.

Depending on where it takes place, the collision may not be ticketable as a moving violation (especially if it happens on private property).

However, there may be some significant financial repercussions.

For instance, if you report the incident to your trucking company, they may count the incident as preventable and it could go in your record or on your DAC report.

We’re not saying it will, just that it could.

As a professional truck driver, you want to protect your record at all costs.

And now that CSA 2010 is being foisted upon the trucking industry, you will want to be very careful how you handle your truck as you don’t want any points to accrue against you.
