Sorry guys if this was asked before.

My wife was told that she has to take an exam if she wanted to have Restriction 4 (Automatic vehicles up to 4,500 kgs) reflected on her liscense.

Now the question is..she already have Restriction 2 (Vehicles up to 4,500 kgs), is it necessary still to get the Restriction 4?

From what I reckon, if a person has Restriction 4, she needs to do an exam again to qualify for Restriction 2 if she wants to drive a M/T. Not the other way around..

Please enlighten this poor soul.
