For Lessons And Mock Tests Visit My Facebook Page at / brm-driving-school-201... Today Maddie does a mock test 2 days before her real driving test. What faults can you see? And how could you use it to help with your driving test.
I think you mean appropriate. Generally when you cannot be seen or you think another road user cannot see you and think a warning is helpful. Approaching a hump back bridge or blind corner where there is only space for vehicles in a single direction. Where someone is reversing into you and you cannot move out the way. It is not a substitute for braking, or steering to avoid an accident.
