It’s not always a success. Sometimes test results can be very frustrating. A candidate on test, waited at a similar traffic light signal, intending to turn right, and waited, and waited! Waiting for the filter to come on (which a ‘part time filter light’ doesn’t always do). So waiting at a green light, when the road is clear to turn cost the test. It is so frustrating when a test is lost due to such a ‘rule of the road’ issue, especially as this is something we specifically discussed during the training day. Green means, Go if the way is Clear.
