The CAA is reminding drivers to take extra precaution on what can often be a drowsy Monday morning commute.
A study shows that an increased risk of fatal crashes persists for the first six days of Daylight Saving Time because clocks spring forward and people lose an hour's rest.
Drivers are encouraged to watch for the warning signs of drowsy driving to keep roads safe including the inability to recall the last few kilometers driven, having disconnected or wandering thoughts and difficulty focusing or keeping your eyes open.
Other signs are feeling as though your head is very heavy, drifting out of your driving lane, yawning repeatedly, accidentally tailgating other vehicles and missing traffic signs.
The CAA urges drivers to find a safe place to pull over when they're fatigued.
Ontario collision data indicates that the direct cost of fatigue-related motor vehicle crashes is estimated to be approximately $393-million.
