How many inches of water will typically come up to the door of most cars?

Typically, about six inches of water can reach the bottom of most car doors. This is significant because even though six inches might not seem like a lot, it can still be enough to cause a vehicle to start floating, particularly lighter vehicles. When a car starts to float, the driver may lose control, and the vehicle could potentially be swept away in a strong current. Therefore, it is crucial for drivers to understand this threshold to avoid driving into flooded areas.

The other measurements provided do not reflect the common height at which water reaches the door. Four inches, five inches, and seven inches do not align with standard estimates, which help maintain awareness of the dangers associated with flooding. Having a clear understanding of this can enhance decision-making when approaching potential water hazards on the road.
