Tucker was on his way to a job interview when he saw a auto roll over and crash on Post Road East in Westport on Wednesday.
With the help of a few other pedestrians, Tucker pulled the man from the wreckage and used the crisp, clean shirt he had been given for the interview to tie a tourniquet around the stranger's head.
He told WABC-TV it was "the right thing" to do.
Aaron Tucker, 32, spotted the vehicle then asked the bus driver to stop so he could help the man trapped in his smoldering auto.
The incident happened when Tucker was on his way to an interview for a bus boy at Dinosaur Bar-B-Que in Stamford, Connecticut. The bus driver told Tucker that he had a route schedule to keep and was not going to help and would leave Tucker if he left the bus.
Tucker went to the vehicle from the passenger's side so he could unbuckle the driver's seat belt and remove him from the overturned auto. Its goal is $25,000 to help Tucker and his loved ones.

He said: "It didn't go through my head, because a job can come and go, but a life is only one time".
An ambulance arrived and took the man to Norwalk Hospital where he is in stable condition, the Westport News reported.
"It didn't go through my head, because a job can come and go, but a life is only one time".
Westport community activist Kami Evans says that the community has joined in praise for Tucker's actions.
"What I have found wonderful about his is it's just not about Aaron anymore", Dale said. It is only after the victim was tended to that Tucker realized that he was too late to show up for the interview, a job that he badly needed to be a better father to his 21-month-old son, who lives with the mother.
