When your driving along and you see the surveyors on the side of the road using the tripod things... what do they do?

I think you'll find it is a theodolite. A theodolite is an instrument for measuring both horizontal and vertical angles, as used in triangulation networks. It is a key tool in surveying and engineering work.

A wild selection of answers good and bad. To get some real information, try an internet search on "surveying."

They are called theodolites and levels. The surveyors are using them to measure distances and levels.

sometimes they are there to measure things like mountains or other things that cannot be measured physically. They take the angle and how high it looks from two points, and then using trigonometry find the actual height of it.

maybe you are referring to a transit levels which are the basic instrument for surveying. it has lots of usage like measuring elevations, distances etc. visit the web page for more.

They are called reflectors. They are also used as a signal of caution in the day.
