Is it legal to make driver to pay for preemployment drug screen?

Recently, I applied for a CDL Driver position with a NY based employer. After successfully passing a Road test they are sending me to go thru physical examination and drug test to their approved medical office, and it says at the paperwork they gave me " Driver is responsible for payment - $110. " And they said it's a company policy. By the way, I have my own medical certificate current (which expires in 10/2014). So, my question is- is it legal for them to make prospective employees- drivers paying for their drug/physical test, regardless of a result of it, without any reimbursement later? It could be legal in some states and illegal at some other ones, but I really want to know how is it in NY.

 

That's Bus company... when I'll check some others I'll see whether it's common for bus companies.. obviously, they don't have as much need in drivers as trucking companies do - there are lots of class B bus drivers drivers who never been in trucking business, and they'd rather pay for it to get a job that'll enable em to sleep at home every (or every other) night...
