The 'T'

A 'T' intersection is a three way intersection. You can either go left or right. The street is shaped like the letter 'T' so people call it a 'T'. Sometimes they don't call it a 'T'. Other names for a 'T' intersection you might hear are more descriptive. Here is a list.

'When the road ends...'
'When you can't go anymore...'
'Three way intersection...'

"At the 'T' intersection, turn right. It is just around the corner."
"When you pass a gas station, you will come up to a 'T'. Take a left, and then an immediate right."
"Go down this road until it ends. Turn left at the 'T' and you will see the gas station on your right."

Dead end

This isn't a direction terminology, but dead end is a road that has only one entrance. That means the only way out is the way you came in. All dead end streets will have a sign at the entrance with the word 'Dead end'.

If you are going to a location that is in a dead end, someone might use this word.

"Turn right on 117th. It's a dead end. We are on the right hand side at the end of the street."

"There are three places to turn right. The second one is a dead end so make sure you don't go in there."

"I live in a dead end street. It's nice because there isn't much traffic."
