Traffic Drums Can Roll Over?

Believe it or not, there are more features than one would expect with traffic drums.  For example, did you know that traffic drums have lips on the bottom that makes it so if they were to fall over, they wouldn’t toll too far?  Actually, not all of them have lips, some are shaped like an oval which also prevents them from rolling.

This may not be the case with every single traffic drum that exists (because there are a lot) but it is a spec that needs to be met in most cases in order to be used on highways.  A lot of states also have specific reflective specs, so watch out for that next time you buy traffic drums.
