Editing Traffic cone (section)

=== Other forms ===
Cones are easy to move or remove. Where sturdier (and larger) markers are needed, construction sites use  [[Construction barrel|traffic barrels]] (plastic orange barrels with reflective stripes, normally about the same size as a [[55 gallon drum|200-liter (55 gallon) drum]]. When a lane closure must also be a physical barrier against cars accidentally crossing it, a [[Fitch barrier]], in which the barrels are filled with sand, or a [[Jersey barrier]] is used.

In many countries such as [[Australia]] and in some American states such as [[California]], traffic barrels are rarely seen; pillar-shaped moveable [[bollard]]s are instead used where larger and sturdier warning or delineation devices are needed. Typically, bollards are {{convert|1150|mm|in|abbr=on}} high fluorescent orange posts with reflective sleeve and heavyweight rubber bases. Larger devices such as [[barrier board]]s may be used instead of cones where larger areas need to be excluded or for longer periods.
