Good question; there are a number of links you could have included in the explanation, but one of my favourites is this by Kalen Delaney:

Thanks for the question, but please explain why:
No, you can never rollback a transaction with a TRUNCATE TABLE statement, regardless of recovery mode
isn't also correct?

Explanation
there is no documentation on a non-existant concern
I disagree. Here is the link: http://msdn.microsoft.com/en-us/library/ms191544.aspx
Transact-SQL Statements Allowed in Transactions
You can use all Transact-SQL statements in an explicit transaction, except for the following statements:
ALTER DATABASEALTER FULLTEXT CATALOG
ALTER FULLTEXT INDEX
BACKUP
CREATE DATABASE
CREATE FULLTEXT CATALOG
CREATE FULLTEXT INDEX
DROP DATABASE
DROP FULLTEXT CATALOG
DROP FULLTEXT INDEX
RECONFIGURE
RESTORE
...
UPDATE STATISTICS can be used inside an explicit transaction. However, UPDATE STATISTICS commits independently of the enclosing transaction and cannot be rolled back.
Based on this article, one can conclude that a TRUNCATE TABLE statement can be rolled back.

Because you can rollback a transaction with a TRUNCATE TABLE statement?

I wanted to comment that this question is superfluous, that everyone knows this. But.....
At the time of writing:
"Incorrect answers: 56% (52)"
And 34% of them are for "you can never rollback a truncate table statement"

Maybe they are Oracle refugees? :hehe: http://www.sqlservercentral.com/articles/Raw+Materials/71108/

Nice and important question. This issue is coming up time to time when discussing differences of delete and truncate operation.

A TRUNCATE can be rolled back in Oracle as well....
I've never used Oracle, so I can't speak from experience - but the official Oracle documentation disagrees with you:
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_10007.htm
"Caution:
You cannot roll back a TRUNCATE TABLE statement, nor can you use a FLASHBACK TABLE statement to retrieve the contents of a table that has been truncated."
