Beware when driving east on Medical going towards the highway, as the new pre I for SA north has just opened up for the school year. There is no school zone sign when heading east from Fredericksburg road toward interstate ten. The zone begins in front of signature ridge apartments and ends about half a block from the access road to I 10. There is no posted school zone sign (20mph 7-9 2-4) only a triangular yellow sign, like a children crossing sign. There is a school zone sign in the other direction, driving from the highway then turning onto medical. This is a new school that wasn’t there last year and most people aren’t aware of it. Its on medical right in front of the back entrance to Carmax.
