You need to put all the methods kart is calling in the try not just the the one method call. I think this is because kart can throw the exception at anytime. I'm still new my self to this, and any more clarification would be nice.

public class Main {
    public static void main(String[] args) {
        GoKart kart = new GoKart("yellow");
 try {
        if (kart.isBatteryEmpty()) {
          System.out.println("The battery is empty");
        }
        kart.drive(2);

        kart.drive(100);
      }catch (IllegalArgumentException iae) {
        System.out.println ("Alert");
        System.out.printf ("There was an error: %s \n", iae.getMessage () );
      }
    }
}```

Not sure where the 100 came from, but the 2 should also cause an Exception right? The battery isEmpty and any attempt to drive will throw an exception.
