A space cushion is a buffer around your vehicle that you maintain to allow room to maneuver, if necessary. Know what is in your space cushion, scan frequently and maintain awareness of other vehicles.
- Keep at least a three-second following distance in front of you – four or five seconds in inclement weather.
- If another vehicle is tailgating you, use your turn signal and change lanes, as soon as it is safe to do so.
- If a driver near you is driving erratically or aggressively, put distance between you and the other driver by slowing down or changing lanes.
