What should you generally avoid doing while driving on a long trip?

Answer: B — Staring at the road for long periods

Staring at the road for long periods can lead to a phenomenon known as highway hypnosis, which is a state of mental distraction that can occur during long driving sessions. This condition often results in reduced alertness and awareness of the surroundings, increasing the risk of accidents. Regularly checking mirrors, looking around, and taking breaks helps maintain focus and reduces fatigue, making it safer to drive over long distances. Though the other activities listed, like listening to music or eating snacks, can vary in their distractions, they do not inherently cause the same level of cognitive disengagement from driving as prolonged fixation on the road can.
