Tip of the Month:  Autumn Driving Tips

It’s that time of year for the season to change from Summer to Autumn.  The leaves are changing colors, the temps are cooler, football is well under way and the holidays are upon us.  Our days are getting shorter, the nights are longer and there is potential for more rain and frost on the ground.  What does this mean?  That the driving conditions are also changing, and winter is coming.

Here are some helpful tips for driving during the Autumn season:

  • If you notice there are leaves in the roadway, be cautious as these can make the road slippery. When applying your brakes, do so gently to avoid sliding.  Also, leaves can hide the painted lines on a road from view along with bumps and potholes.
  • If it’s been raining be careful of standing water, which can cause hydroplaning.  Be careful prior to any puddles appearing, rain - especially if it’s the first in a while – can pool on any oil, grime and dust that is  on all roads making the pavement slick.
  • Don’t forget about those brisk mornings with frost on the ground! Those can definitely cause slippery conditions. Especially on bridges and overpasses.
  • Be conscious of glare from the sun, with the shorter days, you will more than likely be driving during sunrise and/or sunset more regularly and may have a chance of driving into the sun. Make sure you have sunglasses on hand.
  • If you are doing any traveling for the upcoming holidays, make sure to check the highway reports to prepare yourself for a potential change in the weather. You could go from sunshine to snow falling in a matter of miles. See below for links to state travel websites.
  • Keep an eye on your tire pressure as the temperatures drops. You can lose 1 pound of pressure for each drop in 10 degrees. Check your tread as well. Make sure that you still have good tread for the fall and upcoming winter conditions.
  • Check your windshield wipers and make sure they are in good working order. You should change them out every 6 months to a year. This will ensure that they are able to keep your window streak free and clear all the rain off as well. 
  • It’s always good to have a roadside emergency kit, along with water, warm blankets, and food, just in case.

Remember to allow for a safe following distance, be prepared for the conditions and be safe!

In an effort to keep the citizens of Benton County informed, upcoming construction projects are posted on the County's Facebook page, you can also find information about closures and detours on the main Benton County website. Pothole repairs, maintenance and other road repairs may slow your drive and, quite possibly, tax your patience. Stay calm, slow down and be aware of the conditions around you. Be especially careful driving through work zones. Increase your following distance and avoid distractions.
