It has been proposed by the National Traffic Safety Administration (NTSA) that drivers on highways be connected by means of in-vehicle devices, many of which may be suitable for performance by the driver while driving if performed via an auditory-vocal interface. This would ensure that they get timely help in case of an emergency. According to the National Traffic Safety Administration, with an in-vehicle device a driver in distress may easily be able to communicate his situation, without having his hands off the wheel and their eyes off the road. However, the Automobile Safety Association (ASA) has opposed the move, stating that the adoption of voice-based systems in the vehicle adversely compromises traffic safety.
Which of the following, if true, logically validates the contention of the ASA?NTSA says voice based in vehicle devices help drivers in emergencies without taking hands off the wheel or eyes off the road. ASA says voice based systems still reduce traffic safety.
A. The ASA has compiled evidence of accidents that have taken place when drivers engaged in similar conversations using mobiles.
This is suggestive, but it is not airtight. Mobile use can involve extra risks that are not purely voice based (like handling the phone), so this does not cleanly prove the in vehicle voice system itself is unsafe.
B. A conversation is helpful to keep long-distance drivers to remain awake and avoid weariness and sleep, thus avoiding accidents.
This goes the other way. It suggests conversation can improve safety, so it does not validate ASA.
C. The ASA estimates that drivers will become more liberal in driving discipline as they would, when possible, avoid pulling off the road when using the in-vehicle device.
This is speculative behavior, not a direct safety mechanism. It also does not show that the voice system itself causes unsafe driving.
D. As mental engagement increases in distress, reaction time slows, and drivers scan the road less and miss even visual cues right in front of them.
This directly supports ASA. Even if hands and eyes stay on task,
cognitive load from a voice interaction during distress can slow reactions and reduce scanning, which is exactly how traffic safety can be compromised.
E. According to the ASA, of all road accidents due to driver negligence, a major percentage involved deliberate acts of commission by drivers such as talking while driving.
This is correlation and also too broad. It does not isolate voice based in vehicle systems, and “talking while driving” can cover many situations.
Answer: (D)
