Have a Balanced Stance
You need to have a balanced stance in order to avoid both hook and slice. Slice is more common of the two problems and in order to correct it, most people over compensate and drag the ball the other way. Ideally have the right posture when swinging and you should not be falling over. Driving the ball off balance often results in a slice.
Bring Driver from a Round Angle
Bring down the driver in a round motion which will help in avoiding the slice. Make sure that you do not have it too round as it will cause a hook. Have a nice fluent motion with a balanced approach to the ball to get the right drive in.
Don’t Close the Face of the Driver
Often in order to correct the slice in the driver, people start turning the face of the driver’s head a little too much. It is imperative that this is avoided or done in moderation so that the hook is very slightly and only enough to keep the ball into the fairway. Try to bring the driver’s head down straight and that will help you in hitting straight.
Practice with a Pro
Practice with a professional player and seek his or her advice on how you can improve your swing and control the two drive related issues. Tips from a professional can go a long way to help you in improving your game in general.
Use Better Balls
Recently some companies have come up with balls that are easier to control with better dimples on them. The idea is to have a back spin rather than a side spin. As a result, every time the balls starts drifting to one side, the back spin caused by the dimples stops that motion and helps it in moving straight.
