How do deer know to cross at the deer crossing signs?

Answer 1

Actually, they don't. Have you notice the signs are facing the wrong way. If they were facing the correct way, we would barely see them because we would only see the edge. The yellow side should be facing away from the roads so the dear can see the sign, not us.

Answer 2

well the people who put the signs up took notice the deer cross there so they put up a sign to let the other people that don't drive on that specific road every day know that deer are there so the driver can watch out for deer.

Answer 3

Well, people watch deer over time and figure out where they cross the street the most, then put a sign there.

Answer 4

The deer don't know -- the people who put up the signs know. Deer will use a certain path to cross a road and use only that habitually.

Answer 5

Often these signs are put up to warn that deer cross the road at varying intervals along the road.

Answer 6

There is a bridge by Houston that has a picture at the top of the bridge of a deer, so I guess suicidal bridge-jumping deer are a problem around there.

Answer 7

They know because the sign tells them so. The deer sign is to deer, just like what a toilet sign is for man. So you won't enter the wrong toilet. same applies to deer.

Answer 8

Natural selection -- the ones that don't cross at the signs get run over and drop out of the gene pool. Eventually crossing at the signs becomes a key survival trait.

Answer 9

Deer have to be the dumnist animals alive ,,, which when they cross the street they are .

Answer 10

Fools!! Deer can read the signs / understand the pictures, however you want to put it, but they choose to ignore them and like to get hit over...

The mentality.
