The use of radar detectors in commercial vehicles was banned because commercial truck and bus drivers were using these devices to drive faster than the posted speed limit without fear of arrest. Since drivers of noncommercial vehicles also use radar detectors and since speeding decreases safety for any vehicle, use of radar detectors should also be banned in noncommercial vehicles to increase safety.

Which of the following, if true, most strongly supports the argument above?


A. The average noncommercial-vehicle driver is involved in less long-distance driving than is the average commercial-vehicle driver.

B. In many places airplanes or helicopters are used rather than radar to locate vehicles traveling faster than the posted speed limit.

C. The ban on radar detectors in commercial vehicles has been effective in deterring them from speeding.

D. Traffic accidents involving a truck or bus generally pose a greater threat of injury or death than do other accidents.

E. Radar detectors are sometimes set off by devices other than the law enforcement devices that the radar detectors were built to detect.

IMO C

option C provides with a reasoning of the effect of ban of radar detectors on commercial vehicles , so the same effect would come on to non commercial vehicles as well & lower speed means increased safety ...

The use of radar detectors in commercial vehicles was banned because commercial truck and bus drivers were using these devices to drive faster than the posted speed limit without fear of arrest. (So the radars aided in driving fast without fear of arrest And banning them must decreased chances of going faster than speed limit)

Since drivers of noncommercial vehicles also use radar detectors and since speeding decreases safety for any vehicle, use of radar detectors should also be banned in noncommercial vehicles to increase safety. (author is suggesting that banning radars in noncommercial vehicles can improve safety and this improvement in safety can be attributed to the noncommercial vehicles observing speed limit)

A. The average noncommercial-vehicle driver is involved in less long-distance driving than is the average commercial-vehicle driver. (Wrong - Distance is not a factor in safety)

B. In many places airplanes or helicopters are used rather than radar to locate vehicles traveling faster than the posted speed limit. (Wrong - Helicopters and airplanes are out of scope for this argument)

C. The ban on radar detectors in commercial vehicles has been effective in deterring them from speeding. (Correct - if the ban was not effective in commercial vehicles, its unlikely to be effective in noncommercial vehicles. So for the ban in noncommercial vehicles to work, it must have been effective in commercial vehicles first)

D. Traffic accidents involving a truck or bus generally pose a greater threat of injury or death than do other accidents. (Wrong - Traffic accidents are out of scope)

E. Radar detectors are sometimes set off by devices other than the law enforcement devices that the radar detectors were built to detect. (Wrong - Other devices arre out of scope)
