What must you check at the emergency exits before setting off?

You answered correctly. Before setting off, you must check that emergency exits can be opened easily (by ensuring they have the necessary opening devices) and that nothing, such as luggage or objects, is blocking them. These checks are essential for passenger safety in case a quick evacuation is needed. While lighting can be helpful, the main requirements are accessibility and proper functioning of the emergency exit mechanisms. Always remember to make sure exits are clear and operable before departure, especially when responsible for passengers.
