Make every drum, sign and barricade harder to miss.
Spin Alert is a lightweight, wind-powered hazard warning device. It mounts on barrels, barricades, attenuators, barrier walls and road signs. Its spinning motion catches drivers' attention during the day, and its high-intensity reflective sheeting stands out at night. It needs no batteries, wiring or charging.
- FHWA approved
- Wind powered, no batteries
- Under 2½ lb
Results from agencies using Spin Alert
Fewer incidents on county roads
Allen County Highway Department, Indiana, 2009
Reported a significant reduction in incidents when Spin Alerts were used on warning and regulatory signs.
Fewer crashes at barrier walls
Georgia DOT, 2011
Reported a very significant reduction in crashes and incidents when Spin Alerts were used on crash cushions and barrier walls.
“It is brighter and more reliable than most battery-powered flashing lights. It is cost effective, uses no batteries, and requires no maintenance.”
Mike Eckert, Tech Services Manager, Allen County (IN) Highway Department
Motion gets noticed. Reflection gets seen.
Approved by the FHWA in 2009, Spin Alert adds an extra degree of attention to any traffic control device. It works in daylight, at night and in bad weather such as rain, sleet, snow, fog and smoke, which is when drivers need the extra warning most.
Wind turns the rotor
Passing traffic and natural breezes keep the vanes turning. The marker needs no power source.
Motion draws the eye
People notice movement in their peripheral vision before they notice a fixed shape. The spinning vanes help drivers spot the device sooner.
Sheeting returns headlights
High-intensity reflective sheeting on each vane reflects headlights back toward the driver, so the motion is still visible after dark.
In use on roads and work zones
Spin Alert fits the devices agencies already put out: channelizing barrels, barricades, crash cushions, barrier walls and warning and regulatory signs.

Built for the field, not the maintenance schedule
Wind-powered operation
Powered entirely by wind for continuous operation. There are no batteries to replace and no external power to run to the work zone.
Better hazard visibility
Its spinning motion makes drivers notice hazards and important signs sooner, giving them more time to slow down or change lanes.
Sustainable energy design
Wind is its only energy source, so there are no electrical connections and no spent batteries to throw away. That makes it a simple choice for agencies with sustainability goals.
High-intensity reflective sheeting
High-intensity reflective sheeting combined with spinning motion makes a hazard warning device that stays highly visible in both daytime and nighttime conditions.
Two sizes, a range of colors
Both sizes weigh less than 2½ lb. 3M Diamond Grade fluorescent yellow and fluorescent orange are the most common sheeting colors, and other reflective colors are available.
Standard, on a 12″ mounting bracket
For barrels, barricades, guide rails, and smaller regulatory and warning signs close to traffic.
Large, on an 18″ mounting bracket
For extra conspicuity on any traffic control device, including attenuators, barrier walls, and larger regulatory and warning signs.
4″ × 3″ L-brackets for mounting on horizontal or unlevel surfaces are sold separately.
