The '10-20 minute nap' strategy for combating driver fatigue is most effective when:
-
A
Taken while the vehicle is in motion with a co-driver watching
-
B
Taken before severe fatigue sets in, combined with caffeine (taken just before the nap so it takes effect on waking)
-
C
Taken after a full 8-hour driving period
-
D
Taken lying flat in the cab throughout the night
