A terrifying footage show tourists' close encounter with a tiger as it checks out their safari truck that has no doors. The alarming footage was shot during a safari at the Umred Karhandla Wildlife Sanctuary near Nagpur in India.

While the point of a wildlife trek is undoubtedly to get close to some of the spectacular animals of the bush, in this video, there are very obvious safety aspects that appear to have been neglected. The tourists somehow managed to remain calm despite their truck appearing to have no doors.

The video starts with the tiger walking stealth-like towards the vehicle. While the driver and the front seat passenger sections appear to be covered, there is no roof or doors for those seated at the back.

A man appears in shot, and while he remains calm as the big cat springs forward, his silence is perhaps only to be expected. The driver appears to have also vacated his seat so if anything should go wrong, a quick exit is less than likely.

The tiger lets out a couple of grunts before beginning an assault on the wing-mirror using its mouth and paws in an attempt to wrench it off. After giving up on that attack, the tiger then paces past the truck, and this is where it becomes apparent that there is practically nothing separating the group of people in the back from the ferocious beast.

As the tiger moves past, some of the people feel it is safe to whisper, but then quiet returns once more as the animal decides to return. Then one man returns to face front and appears scared to even look towards the predator.

As the tiger moves off again, the tourist group regain their confidence, with chatter resuming, and one person leans out with a smartphone to get a snap to treasure.
