As a defensive driver, you should always be aware of what the drivers around you are doing. Below are some signs that may indicate that the driver of a vehicle is impaired. Most impaired drivers are either overly cautious or reckless. Be on the lookout for drivers who are:

• Making unusually wide turns.
• Straddling the centerline or driving with their tires on the centerline.
• Driving with head out the window, or driving with all car windows down in very cold weather.
• Almost hitting another vehicle or other object or person.
• Weaving or swerving.
• Driving on the shoulder or in the emergency lane.
• Driving with excessive speed or very slow speed.
• Stopping without apparent cause.
• Following too closely.
• Drifting or braking erratically.
• Driving in or crossing into opposite lanes of traffic.
• Changing speeds rapidly or very slowly.
