Sounds like the NJ test!
They don't require a road test if you produce your UK drivers license, but you must take the written.
I failed the first test because of my interpretation of the questions...
Here is an example:-
Question - Your car is approaching a corner, what will it do?
A1 - Slow Down
A2 - Turn the corner
A3 - Go straight on
A4 etc etc

The key is "your car" not "you, in your car"
