Final answer:
To ensure visibility, inspect the car's headlights and turn signals, which use mirrors to direct light and signal intentions on the road.
Step-by-step explanation:
To ensure that other cars can see you when you're driving, it is crucial to inspect the headlights and turn signals on your car. When checking the headlights, observe that most car headlights use a system of mirrors to trap the light from the bulb and form a directional beam. This helps the car to be visible at night and during poor weather conditions. The arrangement of these mirrors is designed so that they direct most of the light forward, allowing your vehicle to be seen from far away. To check the turn signals, make sure they are functioning properly, as they are essential for indicating your intentions on the road to other drivers.
