A
firebreak (also called a
fireroad,
fire line or
fuel break) is a gap in
vegetation or other combustible material that acts as a barrier to slow or stop the progress of a
bushfire or
wildfire. A firebreak may occur naturally where there is a lack of vegetation or "
fuel", such as a river, lake or canyon. Firebreaks may also be man-made, and many of these also serve as roads, such as a
logging road,
four-wheel drive trail, secondary road, or a
highway.
