The Microsleep and Circadian Rhythms campaigns encouraged drivers to recognise the early warning signs of fatigue and to Stop. Revive. Survive.
The Microsleep campaign was launched in December 2001.
The Circadian Rhythms campaign was an extension of the Microsleeps campaign and launched in April 2003.
It highlighted the danger of driving late at night and at dawn. Between 10pm and 6am your body’s circadian rhythms are programming you to sleep and the risk of a fatal fatigue crash is four times greater than for the rest of the day.
