Did you actually mean "Is it safe to drive a car..." not only punto any car it is always less safer to drive in rainy days but be careful and avoid driving through water logged areas. All manufacturer design their cars so that one can drive in rainy season but we should not test our cars in extreme conditions. But driving in monsoon is very exciting and you must go driving and enjoy !! Remember sometime you may have to go out for some urgent reason in heavy rain, so be experienced in rainy seasoned driving. Parts may get damaged anytime due to many reason but we should put our cars to its actual use that is take us to places safely in any weather conditions. I love rainy season driving in ghats, so challenging and exiting !!
