I only had to test the windshield wipers and the windscreen washer fluid!
I heard about a friend of mine who had to test the different types of front lights. He only changed the lights inside of the car and told the inspector they worked. He did in other words not step out of the car to check if they really worked, he just assumed they worked since he managed to change the settings. Sure thing he failed. Taking this into account, please step OUT of the car if you’re going to check the lights!
