Following Google's Event Tracking spec the onClick attribute is added to the anchor tags.

This runs the _gaq.push method when the button is clicked.

_trackEvent is the internal method to run,
Driving School Services is the category (The name you supply for the group of objects you want to track)
Book Now/Sign Up Now is the action (A string that is uniquely paired with each category, and commonly used to define the type of user interaction for the web object)
