Primary Medina County Driving Topic: The Transition From San Antonio-Area Growth to Rural U.S. 90
Medina County’s strongest local driver education topic is the changing character of U.S. 90.
A student traveling west from the San Antonio side of the county experiences a gradual change.
Near Castroville and the eastern county:
Traffic volumes are higher.
Development is more frequent.
There are more commercial entrances and subdivisions.
Farther west:
Traffic spreads out.
Distances between signals increase.
The road becomes more rural.
Agricultural traffic becomes more common.
Nighttime lighting becomes more limited.
A new driver needs to adjust continuously.
Do Not Keep One Driving Style for the Entire Trip
A speed and following distance appropriate in one section may not be appropriate farther ahead.
Watch Speed-Limit Changes
Entering Hondo, Castroville, or another developed area requires earlier speed adjustment.
Do not wait until the reduced-speed sign to begin aggressive braking.
Expect Turning Traffic
Drivers may slow to enter:
Businesses
Residential roads
Ranch entrances
County roads
Farm properties
Watch several vehicles ahead rather than only the vehicle immediately in front.
