When driving on a long trip, you should take breaks every _____.

• A. 3 hours
• B. 2 hours
• C. 1 hour
• D. 4 hours

Answer: (B)

Fatigue is a major safety risk on long drives because alertness and reaction time decline the longer you stay behind the wheel. Taking a break about every two hours gives your body a chance to stretch, hydrate, and reset your focus before fatigue becomes pronounced. This interval balances staying attentive with not interrupting flow too often, reducing the chance of a lapse in concentration. Waiting much longer, like three or four hours, lets fatigue build up; stopping too frequently, such as every hour, can be impractical and may not provide enough rest to reset effectively. So, a break every two hours is the safest, most practical guideline.
