Final answer:
For long trips, it's recommended to drive no more than 8 to 10 hours in a single day to ensure driver alertness and road safety.
Step-by-step explanation:
When planning long trips, it is important for the sake of safety and health to limit the time spent driving in a single day. While there's no one-size-fits-all answer, because it depends on individual endurance and road conditions, a general guideline is to drive no more than 8 to 10 hours a day.
Considering factors like fatigue and the need for regular breaks to rest and refuel, sticking to this range helps maintain driver alertness and overall road safety. It's also crucial to adjust driving times based on personal limits and external conditions such as weather, traffic, and terrain.
