"When you practice hitting your driver at the range take the ball and line up the lines so they are pointed straight then line you feet up on the same line, move the ball back in your stance till it is about even with your left eye (this will feel weird) then try to hit the ball on the left side of the line on the ball. Don't worry about where the ball is going, hit 25-30 like this making sure you are hitting the "inside" of the ball. Once you start hitting the ball on the inside and solid the ball should start out right and then hook back to the left."

All that can be accomplished by keeping the RIGHT (for right handed folks) elbow tucked into the side of the body. A good exercise for this is placing a head cover under you right armpit and keeping it there throughout the swing.
