Most pets are not properly restrained while in the car, and you've got some dangerous situations – for people and pets alike. Unrestrained pets can be seriously or fatally injured, or could even hurt you, in a collision or sudden braking situation. In addition, they're a distraction for the driver, which increases the risk of driver errors. According to a 2010 American Automobile Association (AAA) survey, 2 out of 3 owners engage in distracting behaviors (playing with, feeding or petting their dog, or letting their dog sit in their lap) when pets are in the car...and according to the National Highway Traffic Safety Administration (NHTSA), approximately 20% of injury crashes involve distracted driving.
Please don't become another statistic: only take your pets in the vehicle with you when you absolutely need to, and always properly restrain your pets while in the vehicle.
