Blonde Driver

A blonde was driving down the highway in a snowstorm and she was swerving like crazy. A cop pulled her over and asked her about the swerving. She said, "Well I wasn't swerving until these trees started coming out in front of me." The cop looked at the blonde and said, "What trees?" She sat there and then replied, "Well, I was driving down the right lane and then a tree appeared out in front of me so I swerved left. Then I was driving down the left lane and another tree appeared out in front of me so I swerved right." The cop looked at the blonde again and said, "Sorry, Lady, but that's your air freshener!"
