How Deep Does Water Need to Be to Require a Vehicle Inspection?

[LeviDella]

Water reaching 20 cm requires a vehicle inspection, while for some vehicles with higher chassis, water reaching 30 cm necessitates an inspection. Water can flow backward from the exhaust pipe into the engine, causing stalling or even engine damage. When driving through flooded areas, shift to a low gear and proceed slowly. Never lift your foot off the accelerator when passing through standing water, as doing so can create a strong suction effect in the exhaust system, drawing water into the engine. Precautions for water entering the vehicle: 1. Never attempt to start the vehicle if it has taken in water; 2. Calmly assess the surroundings—if the water level continues to rise, abandon the vehicle promptly to escape; 3. If the engine stalls suddenly while driving through water, do not attempt to restart it.
