Smashed

Car vandalism is neither a trick nor a treat, but the Insurance Institute for Highway Safety says that it's just as much an after effect of Halloween as candy-induced stomach aches and throwing away rotting jack-o'-lanterns. According to IIHS data, cars are, on average, twice as likely to be vandalized on October 31 – sometimes even with slashed tires and broken windows.

The report says that between 2008 and 2012, there were an average of 1,253 insurance claims for vehicle vandalism on Halloween night, compared with just 692 claims for an average day. Though significantly lower than Halloween, the Fourth of July and New Year's Day were also above average in terms of vandal strikes. Conversely, Christmas and Thanksgiving were major holidays that rated below average for vandalism.
