Which of the following activities can distract a driver while operating a vehicle?

Eating a snack while driving can significantly distract a driver. This activity requires using one hand to hold the food, which may cause the driver to steer with one hand, affecting vehicle control. Additionally, trying to unwrap or handle food can divert a driver's visual attention away from the road, increasing the risk of missing important visual cues, signals, or pedestrians. Distractions like eating can lead to delayed reaction times to sudden changes in traffic, compromising safety both for the driver and others on the road.

In contrast, checking the rearview mirror is a necessary and basic driving activity that contributes to safe driving by offering awareness of surrounding traffic. Using turn signals is an essential practice for communicating intentions to other road users, helping maintain traffic flow and safety. Maintaining speed is integral to driving and helps ensure the vehicle is operating within legal limits, which enhances road safety and minimizes the likelihood of accidents. These activities are part of safe driving practices, whereas eating diverts attention and increases the possibility of distraction.
