MetroAccess drivers have been caught falling asleep at the wheel 87 times in less than three years, according to agency statistics. One driver was busted after running into a curb and blowing a tire with two disabled riders aboard.

The drivers who were caught had been working eight-, 10- or 12-hour shifts, but Amalgamated Transit Union Local 1764 President Wayne Baker worries his drivers will have even more trouble staying awake when Metro moves them to 13-hour shifts later this week. The drivers will be driving for 12 hours and have a one-hour break.
