Wisconsin drivers need to work on their manners. That's according to a #DriveHuman survey conducted by the website Kars4Kids.com.

The survey's goal was to find out which states have the most courteous drivers.

Wisconsin ranked 46th in the nation, receiving a D- driving score. Louisiana, Arkansas, South Carolina, and New York ranked below Wisconsin on the list.

Idaho has the most courteous drivers. Illinois ranked #31.

Wisconsin drivers get low grades when it comes to responding to slow driving (C-); letting another car merge into heavy traffic (F); and stealing parking spots (F).

Here's how the survey reached its conclusions: Fifty licensed drivers in each state were asked a series of questions about driving habits.

The survey was conducted from March to April 2017. The sampling error was +/-12 percent with a confidence level of 90 percent.

The #DriveHuman campaign says its mission is to to encourage courteous driving.
