Rat running

Despite the traffic calming curb extensions, heavy traffic means that the narrow residential street is still appealing to motorists desiring a shortcut.

Rat running (also known as rodent running or cut-through driving) is the practice by motorists of using residential side streets or any unintended short cut such as a parking lot, delivery service lane or cemetery road instead of the intended main road in urban or suburban areas.
