Would you know what to do if you got stuck in a sinking vehicle?
TikToker @catherinestories posted a clip on the video-sharing platform, where she explains what to do if you ever find yourself underwater in a vehicle.
It's all about acting quickly, with Catherine explaining the first step is to try and break your window before the vehicle becomes submerged.
"Here's the only way to survive when you're stuck in a sinking vehicle," Catherine began.
"As soon as your vehicle makes contact with the water, undo your seatbelt and roll down the window as fast as you can. "Once you've done that, immediately get out through the window before your vehicle is fully under water. You won't be able to open your door because of the force of the water pressing from the outside.
"If your window won't roll down you need to break it. You can use a heavy object like a hammer, or you can buy a special car window breaking tool online that you can keep in your vehicle."
Catherine explained that if you cannot find anything to break the window, you can use your headrest by hitting the window with the metal prongs.
"If you still cant get out through the window, wait until your vehicle is fully under water so the pressure inside and outside is equal," Catherine added.
"Then with the small amount of air left in your vehicle, take a deep breath, open the door and follow the air bubbles to the surface."
Other followers were quick to comment on the video, with many admitting they didn't realise it would be difficult to open a car door as it sinks.
There are many theories on the best and quickest way to get out of a sinking car, but SmartDriving.co.uk explains that 'it seems that the best course of action is to try and get out as soon as possible'.
"Some people suggest that you should shut the windows to slow down the rate at which the car fills with water. The theory is that the pressure inside and outside needs to equalise before you can swim out or attempt to open a door," they explain.
"However, other tests, notably one shown on British television, have shown that it can take too long for the equalisation process or that the force of water rushing in can make it impossible to escape."
For this reason they also advise escaping via the windows. They also say it's a good idea to switch on all the cars lights (if they still work) to help rescuers see where you are.
