For drivers, bikers and pedestrians.
Although New Year's Eve and New Year's Day is a time to party, things can also turn deadly. According to the Insurance Institute for Highway Safety (IIHS), New Year's Day is the "deadliest day on average for alcohol-related crashes" involving cars and motor vehicles in general. IIHS researchers conducted a five-year study and discovered that "every New Year's Day, an average of 70 lives were lost in crashes in which at least one driver, pedestrian or bicyclist, had a blood alcohol concentration (BAC) of 0.08 percent or higher."
In fact, 62 percent of the average of 113 crash deaths on January 1 are because of drunk driving. Just to compare, that's almost double "the overall impairment of 35 percent during the 2011-15 period." But it's not only drivers who are in danger on this particular day. This is also the deadliest day for occupants of all types of vehicles, with "an average of 83 lives being lost in passenger vehicle crashes on New Year's." By comparison, an average of 59 people died in passenger crashes on any given day from 2011-2015. Not to frighten you any further, but pedestrians and cyclists must also take extra precautions on New Year's for fear of being struck by a drunk driver.
But walkers and bikers can also be drunk and stupid, too. In 2015, for example, "46 percent of pedestrians and 36 percent of cyclists age 16 and older were killed in crashes between 9pm and 6 am with BAC levels at or above 0.08 percent." Have fun but be safe this New Year's. Don't start 2017 out the wrong way.
