Final answer:
Wearing a headset that covers both ears while driving is not only dangerous but also illegal. Having one or more interior lights on is dangerous but not illegal. Using cruise control on residential streets is dangerous but not necessarily illegal.
Step-by-step explanation:
Among the options provided, wearing a headset that covers both ears is dangerous while driving and is also illegal. This is because wearing such a headset can significantly impair the driver's ability to hear important sounds on the road, such as sirens, horns, or other vehicles. It can lead to accidents and endanger the driver and other road users.
Having one or more interior lights on while driving is dangerous but not illegal. However, it can distract the driver and affect their visibility, making it harder to see the road clearly, especially at night. It is recommended to keep the interior lights off while driving for safety purposes.
Using cruise control on residential streets is dangerous but not necessarily illegal. Cruise control is designed for use on highways or open roads with consistent speeds. Using it on residential streets can make it difficult to respond quickly to unexpected situations, such as pedestrians, stop signs, or other cars. It is better to use cruise control in appropriate settings for safe driving.
