Explanation:
When planning rest stops during a long road trip, the most recommended option is a. Every 2 hours or 100 miles. Taking regular breaks is essential for maintaining concentration and avoiding fatigue. It's not just about covering a specific distance; it's also crucial to listen to your body's signals and take a break when you start feeling tired.
Scheduling a short break every couple of hours has been shown to improve overall productivity and effectiveness. Moreover, it provides an opportunity to refuel, refresh, and ensure safety by preventing the potential negative effects of prolonged driving without adequate breaks.
As an example, imagine you're driving at a constant speed; if you have been traveling at 20 miles per hour and covered 80 miles, you've been on the road for 4 hours. In such a scenario, it is highly advisable to have already taken at least two breaks to avoid exhaustion and remain alert while driving. Not to mention, these breaks can also be an opportunity to check your vehicle's condition, refuel if necessary, and adjust plans for unexpected travel conditions.
