Another reason to worry about that big mid-April day... your likelihood of being involved in a fatal car crash increases.

Researchers in Canada have discovered that drivers' risks of being involved in a fatal car crash jump 6 percent on the day when federal taxes are due, a correlation they say has become more prevalent over the last two decades.

Toronto's Sunnybrook Research Institute looked at car crashes on Tax Day - that's April 17th this year - and they compared them to other days in April. Their findings? An average of 13 more people die on Tax Day on the highways in the United States than on other days in April, a notable 6 percent increase.

The Institute's study, which was published in the Journal of the American Medical Association, says that the rise in the fatal crash rate isn't a mere coincidence. In fact, the group says that the increase is not unlike that seen on Super Bowl Sundays. While that statistical anomaly can logically be attributed to impaired judgement caused by alcohol consumed at football game watching parties, the Tax Day statistic is harder to figure out since there weren't more fatalities during evening hours when drinking is most common.

The Institute suggests that deadline stress could lead to increased distracted driving as drivers fret over getting their taxes in on time. Whatever the case, NPR reminds taxpayers that they can always file their taxes early or electronically, which should keep them off of the roads next week.
