For safety check when doing circuit course, you must always look
at the mirror and then check your blindspot before making left or
right turn when driving into S course, Crank course or Directory
Change course.
For vertical and parallel parking, before you reverse the car into
the lot or to move out of the lot, you must be more exaggerated to
turn your head to keep your lookout and also blindspot too on
both side, not just one side. And while you are
reversing your car into the lot, be sure to turn your head back and
look through rearwindow every 5 seconds, and at the same time, keep
your lookout on your both side until your car is in the lot.
This also go to the same thing for directory change course. Hope
this help you
