Q. How does The Bluestar System™ work?

       A.  The Bluestar System™ make freezing temperatures visible to motorists, ahead of the vehicle.


Q. How does it do that?

A. IceAlert® temperature sensitive reflectors are mounted on standard guide posts and change color from
white to blue as the temperature approaches the freezing point.


Q. How will drivers notice this system?


A. The BlueStar System™  symbol is in motorists "cone of vision" (see next FAQ)


Q. What is the "cone of vision"?
A. Imagine the roadway stretching out in front of your vehicle. The area you see is called your cone of vision. It includes pavement markings, guideposts, and signage that help you guide your vehicle. Any change in appearance of these markings is both apparent and noticeable.


Q. Why should we invest in The Bluestar System™?
A. The Bluestar Roadway System™ can reduce the number and severity of accidents by changing drivers' behavior. 


Q. How does it change drivers' behavior?

A. By giving them real time temperature information that can reflect temperature changes. Compare this to a sign that states, "watch for ice" that is there year around.


Q. What do you mean "real time"?

A. The Bluestar SystemTM indicates a potential hazard only when the condition actually exists.


Q. How does it do that?

A. IceAlert® reflectors work as standard white reflective delineators until the temperature approaches the freezing point. Then they turn progressively blue between 36° and 32° F. They are site specific and continuous.


Q. What does site specific and continuous mean?

A. The temperature is reported at each post and is specific to that post. The message is repeated and reinforced by succeeding devices in the series. This information enables the motorist to make better driving decisions.


Q. Will the motorists understand this system?

A. Yes, motorists find The Bluestar SystemTM easy to understand because an explanatory sign precedes it. In addition, we have found that when the reflectors appear along roadways, local media are eager to educate the motoring public.



Q. How difficult is it to install and maintain?

A. The Bluestar SystemTM requires no electricity, pavement cuts, or special posts. It mounts on standard guideposts with hand tools and needs no maintenance beyond occasional cleaning.


Q. How long will the reflectors last?

A. IceAlert® reflectors are very strong and reliable. Made of sealed injection-molded polycarbonate, they are able to withstand repeated and severe shocks to their face. They will provide years of information to your drivers.
