According to news, a lot of taxis either stop driving during this period or they reject fares to go to flooded area. So even Impact might not be flooded but as the roads leading to Impact are flooded now, they would not take you there. There are also passengers complained been ejected half way by cab drivers when they encountered flooded road. So you guys better make sure you have return trip secured before going there. If not you would get stuck there.
6 wheelers or 10 wheelers trucks is what I used to go into flood zones....
