In reply to what you have said kaz, i sat my medium rigid license on Saturday morning. Before the test i had a 2 hour lesson and during that time i was always told to check my mirrors every 15 secs, look up oncoming side streets before you get to them (for idiots mainly) STAY IN THE LEFT LANE and to try to do the same speed as the other vehicles around me up to the speed limit. Truck drivers are trained to stay in the left lane. they are trained in how to deal with other road users including tailgater's. (and no people, you dont speed up or slam on the brakes.)
The test was the toughest test i've had to do. maybe all car testing should be as hard as truck licenses.
oh and truckies that sit in the right lane doing 80 should be made to resit their licenses.
