Can a secondary engine start after vehicle water immersion be detected?

[LeRyan]

Vehicle secondary start after water immersion can be detected. The vehicle will only restart the starter motor after stalling in water, at which point the starter motor won't respond - this constitutes a secondary start. A secondary start refers to the situation where the engine stalls underwater and the driver attempts to turn the ignition key again underwater. Typically, if a vehicle stalls in water, there's a 50% chance of engine damage. However, if the engine is restarted after stalling, the engine will certainly be ruined. Precautions for rainy day driving are as follows: Reduce speed and drive cautiously: In severe weather conditions, strictly control your speed to allow adequate reaction time. Rain reduces tire traction and road grip, so maintain low speeds using second or third gear, not exceeding 30-40 km/h. Maintain clear visibility: Impaired visibility during rain easily leads to traffic accidents. Therefore, promptly activate wipers and adjust their speed according to rainfall intensity to ensure good visibility.
