While icy conditions typically prompt drivers to be more cautious in winter, fall should have the same effect. According to Carfax data, more than 72% of U.S. drivers live in states where autumn is peak accident season.

Moreover, a spokesperson for the National Highway Traffic Safety Administration (NHTSA) tells Yahoo Life that while the total crash rate per 100 million vehicle miles traveled fluctuates throughout the year, in 2022, it was highest in November and December.

Why is this time of year so risky for driving? Here are four factors at play — and tips for staying safe on the road.

Trick-or-treaters are roaming the streets on Halloween
While Halloween is an exciting time for trick-or-treaters, it’s also a dangerous one when it comes to fatal traffic accidents involving pedestrians. According to a JAMA study looking at data over a 42-year period, the relative risk of a pedestrian fatality occurring is 43% higher on Halloween compared with other days, and children between the ages of 4 to 8 are most vulnerable.

As kids take to the streets on Halloween, the NHTSA recommends that drivers practice the following safety tips:

Watch out for trick-or-treaters and other pedestrians, as they may unexpectedly run into the street or be passing by as you back out of your driveway.

Drive slowly.

If you see a drunk driver, contact the police.

To help ensure kids are safer while they trick-or-treat, the NHTSA also suggests that parents:

Assign them a “buddy” to walk with throughout the evening and to walk home with when they’re done trick-or-treating.

Remind them to follow the rules of the road and obey signs and signals.

Encourage them to cross streets at crosswalks or intersections and to always look for cars in all directions.
