The speeding problem and radar speed sign effectivenes

Speeding drivers put others at risk, especially when pedestrians are present in school zones, on neighborhood streets, or in work zones. By dramatically reducing the speed of the worst offenders, SpeedCheck radar speed display signs can mean the difference between life and death. Radar speed signs can slow down traffic in a school zone by as much as 9 mph, according to this study from the Texas Transportation Institute, and several studies have shown a range of around 5 to 9 mph.

Solar sizing matters

Carmanah’s radar speed signs are the most reliable and brightest signs on the market because we’re experts at sizing-up solar.

How do we do it? It’s called a Solar Power Report, and it’s calculated by your site location and the profile of each unique installation site. Our Solar Power Report takes into account environmental factors and product settings.

solar sizing matters

Once completed, the Solar Power Report lets us know what size of solar kit is sustainable year-round, or whether A/C power options may be required for that unique location.

Comprehensive school zone safety treatments

Flashing school zone beacons are the key safety tool for schools to slow down traffic. Additional products may be added that will also encourage drivers to take notice of signs and adjust their behavior. Check your local requirements to determine compliant school zone safety options in your region.

School zones can contain:


Flashing beacons
within school zone areas

Radar speed signs to help drivers self-correct before a school zone
