Are always okay to take when driving as long they are prescribed by a doctor?

No, not all medications prescribed by a doctor are always safe to take while driving. Some medications can cause side effects that impair your ability to drive safely. For example, certain medications can cause drowsiness, dizziness, or blurred vision. Others can slow your reaction time or affect your judgment. If you are taking any medication, be sure to read the label and talk to your doctor about whether or not it is safe to take while driving.
