Is it safer to park in an underground garage or on the road during heavy rain?

[DelJude]

Parking on the ground is generally safer during heavy rain, as underground garages may be at risk of flooding. However, this depends on the adequacy of the garage's drainage system. Below are some key points regarding vehicle water exposure: 1. Do not restart the engine: If the engine stalls during water exposure, immediately activate the hazard lights, turn off the engine, and remove the key. Never attempt to restart the engine, as this can cause severe and irreparable damage, which may not be covered by insurance. 2. Ensure vehicle sealing: If the vehicle is stationary in a flooded garage or parking lot, lock the car and avoid starting the engine. Take all possible measures to seal the vehicle effectively.
