When looking at the association of commute time and incidence of falling asleep while driving, residents who drove for a longer time were more likely to fall asleep. When commute times were greater than one hour, 66% (6/9) reported they had fallen asleep while driving. When asked about car collisions (Table 6), those who drove for a longer time were more likely to have a car collision. Of those who commuted for more than one hour by car, 44% (4/9) reported they had been in a car collision.
