Final answer:
Blind spots are areas on either side of a vehicle not visible through the mirrors and require drivers to physically check before changing lanes or merging. Proper mirror adjustment can minimize, but not eliminate, the risk of these areas. Headlights increase visibility of the car to others, especially in low light conditions.
Step-by-step explanation:
The danger areas to the sides of your car that cannot be seen in the mirrors are often referred to as blind spots. These are zones on both sides of the vehicle that are not visible through either the rearview or side mirrors, making them particularly hazardous when you are trying to change lanes or merge. While driving, it's important to physically turn your head to check these areas to ensure they are clear before making any lateral moves with your vehicle.
To minimize blind spots, you should adjust your mirrors properly. The rearview mirror should display the back window fully, while the side mirrors should be adjusted so that the side of your car is barely visible at the edge of the mirror. However, even with properly adjusted mirrors, you should perform an over-the-shoulder check to verify that the area is clear before changing lanes, as another vehicle, cyclist, or motorcyclist could be hidden in your blind spot.
Remember, it's essential to stay fully aware of your surroundings while driving, and keep your headlights on during low visibility conditions. The lights won't help with your blind spots but will make your car more visible to others, which is crucial for your safety on the road. Warning: Never look directly into bright lights, as doing so can damage your eyes.
