Hi, guys! what is "a crest of a grade" from Overtaking on a crest of a grade? ?

Question

I found this phrase from LTO's traffic regulations table. some other table shows "a crest or a grade" not "a crest of a grade". Isn't it kind of hump? or intersection or crossing part of the road in front of schools? or what? Thanks a lot you guys' precious answers.

Answer 1

A grade is a slope--for example a road slopes or rises (falls) 1 foot in   100 feet--gives "per cent" grade.  Railroads & highways have maximum or minimum grades allowed in their design so the vehicles can move along the road without going excessively fast or slow.  When the grade goes uphill and then turns downhill, you've reached the "crest".  All this to say you wouldn't see the vehicle coming from the other side of the hill and so no "overtaking" or "passing" on a hill to avoid head-on collisions !

Answer 2

To answer your question. A crest would be the top of a hill, a large hill or small hill.

The grade would be the road going up or down.

Answer 3

I think your question has been sent through to the wrong forum, this is genealogy the research of ones family history.
