Final answer:
To prevent fatigue-related crashes while driving, it is essential to prioritize adequate sleep, take breaks during long journeys, and avoid driving when you would normally be asleep.
Step-by-step explanation:
Fatigue-related crashes while driving can be prevented by getting enough sleep before driving, taking breaks during long journeys, and avoiding driving during times when you would normally be asleep. Sleep deprivation can impair your ability to drive by slowing down brain and nervous system functions, decreasing reflexes, and reducing clarity of thinking. It's important to recognize that sleep debt can negatively affect your performance behind the wheel, making it essential to prioritize adequate sleep for safe driving.
