Being trapped in a sinking vehicle is among the most frightening situations a driver can face. While the odds of it happening are low, it’s not as rare as many assume: more than 10,000 water-related car accidents occur in the U.S. each year, and roughly 400 people drown inside their vehicles annually. Staying calm and following the right steps in the right order can make the difference between a close call and a tragedy.
Why Cars End Up in Water
Several common scenarios lead to vehicles entering water. Flash flooding or heavy rain can sweep a car off the road entirely. Bridge or road failures also pose a real risk, with nearly 12% of U.S. bridges rated as structurally deficient. Drivers can also slide off the road into a nearby lake or river due to ice, distraction, or a sharp curve, and collisions near rivers or coastal roads can sometimes end with a vehicle in the water. In most cases, there’s very little warning before a car begins to sink, which makes knowing the correct response essential.
Staying Calm in the First Seconds
Most vehicles float for roughly 30 to 120 seconds before sinking, giving occupants a narrow window to escape. Panic wastes valuable time and clouds judgment, so taking a breath and focusing on a clear sequence of steps is critical in those first moments.
Unbuckling and Preparing to Exit
As soon as the vehicle enters the water, the driver should unbuckle their seatbelt immediately. If the buckle jams, a seatbelt cutter can be used instead, which is why keeping one within reach is a good idea. It’s important to free yourself first before attempting to help other passengers, so you’re able to clear a path to safety.
Opening or Breaking a Window
A window typically offers the best escape route, though timing matters. Power windows often continue functioning for a few minutes even after a vehicle enters water, so rolling them down immediately is worth attempting first. If the windows won’t operate, a window-breaking tool can be used on the side glass, since windshields are significantly more difficult to break through. It’s also worth noting that not all vehicle glass is tempered; some vehicles use laminated glass that won’t shatter the same way, so knowing your vehicle’s glass type in advance and carrying the appropriate tool is recommended.
Helping Other Passengers
Once the driver has freed themselves and identified an escape route, attention can turn to helping others. With children in the vehicle, starting with the oldest child can help, since they may be able to assist younger siblings. For infants in car seats, the entire car seat can be unbuckled or removed and pushed through the window. If a passenger is unconscious, their seatbelt should be cut if necessary, with care taken to support their head, and they should be pushed through the window first to avoid blocking the escape route for others.
Exiting and Swimming to the Surface
Once a window is open or broken, occupants should exit quickly. Since the front of a vehicle typically sinks first, exiting through the windshield area should be avoided. After clearing the vehicle, swimmers should push off and head toward the surface. If disoriented underwater, following the direction of rising bubbles can help identify which way is up; in ice-covered water, swimmers should aim for the hole created when the vehicle broke through the ice. Those who can’t swim should conserve energy and float toward any nearby debris or buoyant object until help arrives.
Special Considerations for Pets and Injured Passengers
When traveling with pets, small animals in carriers should have their carrier pushed out first. Larger animals require a calmer approach to avoid startling them, guiding them toward the window without putting yourself at additional risk. For unconscious passengers, unbuckling or cutting their seatbelt, supporting their neck, and pushing them through the window head-first, then swimming alongside them to the surface, gives them the best chance of a safe exit.
What Not to Do
Opening a door while the vehicle is submerged should be avoided, since it accelerates flooding and sinking, and water pressure makes doors nearly impossible to open once fully submerged anyway. Waiting for the car to fill with water in order to “equalize pressure” is a persistent myth that can waste critical time and increase drowning risk. Calling 911 should also wait until after escaping the vehicle, since every second spent on the phone during the escape reduces the chance of getting out safely.
Preparing Before It Happens
Keeping an emergency tool, such as a glass-breaking hammer or multi-tool, within immediate reach, whether on a keychain or clipped to the sun visor, can save critical time in an emergency. Practicing a simple escape routine with family members, remembering seatbelt off, window open, and exit children first, can also help everyone react more quickly under pressure. Knowing your vehicle’s glass type in advance, since some newer vehicles use laminated glass that ordinary tools won’t break, is also worth checking ahead of time.
After Escaping
Once safely out of the water, swim to shore and call emergency services from land. In cold water conditions, getting warm quickly is important to avoid hypothermia. Even if you feel physically fine, it’s worth getting checked by a medical professional afterward, since adrenaline can mask injuries sustained during the escape.
Why This Knowledge Matters
No one expects to end up in a sinking vehicle, but being familiar with the right steps in advance can make a critical difference if it happens. Keeping the right tools accessible, knowing the proper sequence of actions, and staying calm under pressure all improve the odds of a safe outcome for drivers and passengers alike.
