Tailgating

Tailgating is the practice of driving on a road too close to a frontward vehicle, at a distance which does not guarantee that stopping to avoid collision is possible.

The safe distance for following another vehicle varies depending on various factors including vehicle speed, weather, visibility, and other road conditions. Some jurisdictions may require a minimal gap of a specified distance or time interval. When following heavy vehicles, or in less than ideal conditions (e.g. low light or rain), a longer distance is recommended.
