In the past, roadside design somewhat ignored cut batters feeling that they would be redirective and present a much lower risk than fill batters and fixed hazards (trees, culvers, power poles etc.). However, in more recent times there has been an acknowledgement that cut batters can pose a risk to vehicle occupants leaving the road. This can be from snagging on rocks/protrusions or from vehicles rolling over due to climbing the batter (as per the video below).
Roadside designers should consider appropriate and practical treatments for cut batters, including the use of barrier systems, measures to keep vehicles on the road (audio tactile edge line, sealed shoulders, delineation, speed limit reductions), flattening the batter and smoothing the batter.
