What is an important first step if you find yourself in a vehicle sinking in water?

When you find yourself in a vehicle sinking in water, the immediate priority is to free yourself from any restraints, which is why unbuckling your seatbelt is a critical first step. In an emergency scenario where time is of the essence, getting out of the vehicle as quickly as possible is crucial as the sinking vehicle can quickly become submerged, making escape more difficult.

Once the seatbelt is released, you can then focus on other actions, such as opening a window or swimming to safety. Starting the engine is not advisable, as this can create additional danger, and attempting to swim while still trapped in the vehicle can increase the risk of panic. Calling for emergency services is also important but should not be the first step in this immediate life-threatening situation.
