A hydraulic control device for an automatic transmission includes a reverse inhibit valve for inhibiting a reverse gear position to be established when the reverse range is selected by mistake. This reverse inhibit valve is placed in a selected one of a first state in which a first port communicates with a third port, and a second state in which a second port communicates with the third port, depending upon whether a solenoid pressure is applied to one end of a spool of the valve. If the reverse range is selected during forward running of a vehicle, the reverse inhibit valve is placed in the first state in which the first port communicates with the third port, so that an oil pressure of a friction element is drained through the first port.
