Which of the following is NOT something you should check during a trip?

During a trip, it is vital to prioritize safety and the operational condition of the vehicle. Checking fuel levels, tire pressure, and brake conditions are all crucial to ensure the vehicle can operate effectively without interruption and to prevent accidents.

Fuel levels should be monitored to avoid running out of gas, especially during long trips where fuel stations may not be readily available. Tire pressure is equally important; incorrect tire pressure can lead to decreased fuel efficiency, poor handling, and even tire blowouts. Regularly checking the brakes ensures they are functioning properly and can prevent serious accidents, as they are critical for stopping safely.

In contrast, checking text messages or phone notifications is a distraction from the road and not an essential task for vehicle safety. Engaging with a phone while driving can significantly impair a driver's attention, increasing the risk of accidents. Thus, while it's important to stay connected, it should not come at the cost of road safety, making this the correct answer.
