If you fail your road test, your examiner will tell you why you failed. You should take into account how he/she suggest you improve. You will be able to take the exam three times before you must restart the application process. This means resubmitting the forms and applications and paying the cost of the tests again.
You should expected to be tested on your ability to drive safely and effectively. You should be able to make a quick stop, observe intersections, pass other vehicles safely and use the appropriate lanes.
Remember to pay attention to oncoming traffic. Stay within the speed limit and leave a safe distance between yourself and other cars. Check your mirrors regularly. Always come to a complete stop and keep both hands on your steering wheel at all times.
