A driver may be temporarily blinded at night by which of the following?

A driver may be temporarily blinded at night due to glare from the headlights of other vehicles. Bright headlights can create a significant glare effect, particularly at night when the eyes are adjusted to lower light levels. This glare can momentarily impede a driver's ability to see, leading to disorientation and difficulty in maintaining proper control of the vehicle.

In addition, striking a match to light a cigarette can also result in a brief loss of vision. The flame produces a sudden bright light that the eyes are not prepared for, particularly at night, which can cause temporary blindness as the pupils constrict in response to the brightness.

Thus, both glare from headlights and the flame from a match can cause a driver to experience temporary visual impairment, making it crucial for drivers to be aware of these factors when driving at night. Taking precautions, such as avoiding looking directly at headlights and managing activities that create sudden bright lights, can enhance safety on the road.
