TXDOT has this message on their signs today along SH 99. I 120% agree that motorists should not enter high water. The turn around is what I question. Last month I shot two different head on crashes. One on I-610 South Loop near NRG Stadium in which a Hispanic male saw the sign. A few miles down the road he encountered water over the freeway. HE turned around and as he was westbound in the eastbound lane was hit head on. On another crash was on I-610 east near I-10 where the same thing happened. Think what you would think if you were traveling down the freeway and as you go around a curve or top a overpass you are met by a vehicle coming head on at you.
