OBJECTIVE: To investigate the evolution over 15 years of sleep schedules,
sleepiness at the wheel and driving risk among highway drivers.
METHODS: Comparative survey including questions on usual sleep schedules and
before the trip, sleepiness at the wheel, the Epworth sleepiness scale, Basic
Nordic Sleep Questionnaire (BNSQ) and a travel questionnaire.
RESULTS: 80% of drivers stopped by the highway patrol agreed to participate in
both studies with a total of 3545 drivers in 2011 and 2196 drivers in 1996
interviewed. After standardisation based on sex, age and mean annual driving
distance, drivers in 2011 reported shorter sleep time on week days (p
