Assessing Risk Factors

Ask yourself these questions:

  • Have you been awake for 18 hours or more?
  • Have you had six hours sleep or less in the last 24 hours?
  • Do you often drive between midnight and 6 a.m.?
  • Do you frequently feel drowsy while you’re driving?
  • Do you work the night shift?
  • Do you work more than one job?
  • Do you have any sleep disorders?

If you have any of these indicators you are at a much higher risk of a drowsy-driving crash, even if you don’t feel sleepy. Half the drivers who had drowsy-driving crashes said they felt “only slightly sleepy” or “not at all sleepy” right before the crash.

At risk groups:

  • Commercial vehicle drivers
  • New/young drivers, especially young men
  • Shift and split-shift workers
  • People suffering from sleep disorders
  • Drivers whose lifestyle affects the quality and quantity of their sleep
