Failed my first class 1 test after druving the full test really well one minor. Got back to the test centre for the coupling uncoupling and the bottle went. Hooked up clip in no plate on suzies on forgot brake legs. I could not believe this had the tester shouting and blinding at me. Rightly so. Back the next week and passed with flying colours best way is stay calm no in any situation. Safe to say ave been driving 18 months now and not one bump. Touch wood… expensive mistake. Double check and double double check if you think you have forgot anything
