Remember to set your clocks back 1 hour this weekend as daylight standard time begins on Sunday, November 2nd at 2:00 AM. Also, please be aware of the need to adjust to the earlier darkness in the evening and to be alert, especially when driving or walking about.
A study conducted by Professors Fishbeck and Gerard of Carnegie Mellon University reported in 2007 that after clocks are turned back 1 hour in the fall, pedestrians, from the dusk to dark period, face a three times increased risk of being struck and killed by a vehicle. Apparently, the days immediately following a return to daylight standard time in November show the highest increase in pedestrian fatalities. The risk then declines each month through May. According the the researchers, it's the adjustment to the earlier darkness rather than the darkness itself that is the killer.
Both drivers and pedestrians should be more alert and aware during the dusk to dark transition but especially during the days immediately following the change back to daylight standard time on November 2nd.
