What must you be aware of when driving along narrow avenues?

You answered correctly. On narrow avenues, it is often hard to see into road bends because the view is limited by trees, bushes, or parked cars. That means dangers might appear suddenly, so you must drive especially defensively, anticipating obstacles or oncoming traffic. However, being on a narrow avenue does not protect you from black ice, so that statement is incorrect. Always remain alert and reduce your speed in such areas to respond safely to unforeseen hazards.
