Sleep Apnea Testing

On Feb 6th, the National Transportation Safety Board concluded that the 2016 and 2017 train crashes in Hoboken, New Jersey and Brooklyn, New York occurred because the train engineers fell asleep. The NTSB concluded that the "primary cause" of both accidents was the failure to test the drivers for sleep apnea.

Just a few months earlier the Trump Administration withdrew Obama's proposed rule requiring sleep apnea testing for all railroad engineers, truck drivers, and bus drivers.

What do you think? Should sleep apnea testing be required?
