How many orange stripes must each plastic drum have?

Each plastic drum used in traffic control must have two orange stripes. This design enhances visibility and warns drivers of potential hazards in work zones. The two stripes serve to make the drums more noticeable, ensuring that they can be easily seen by drivers both during the day and at night, thus promoting safety and helping to define the boundaries of the work area effectively. Having two stripes, rather than just one, provides a clearer indication of the presence of traffic control devices, reducing the risk of accidents or driver confusion in areas where the road layout changes due to construction or maintenance activities.
