The problem with low performing road signs

Road infrastructure should provide maximum driving comfort and safety by making the road visible and providing information guidance during day and night.

  • Stop signs
  • Older drivers need more time and light to read signs and make decisions compared with other drivers, whilst truck drivers, spending many hours on the road, are sitting much higher above the headlights of their vehicle¹. This means that for the traffic sign to remain visible, the cone of reflected light has to be much wider.

    The first retroreflective sheeting on the market was based on glass beads with a reflective coating behind these beads. The resulting optics returned 6 to 8 % of the incident headlight towards the light source. But 75 years later technology has enabled this to be almost 10 times better. Since micro prismatic technology was born, reflective road safety signs have experienced continuous improvements. The use of tougher polymers also generates more durable and weather resistant retroreflective films.


Three important characteristics for reflective road signs to consider

In addition to improved retroreflectivity, 3M’s prismatic reflective sheeting materials offer a number of environmental benefits over glass beaded sheeting with a 97% reduction in volatile organic compounds, a 77% decrease in energy consumption and a 46% decrease in solid waste during the manufacturing process.

Frequently asked questions about reflective sheeting for traffic signs

Find answers to some of our frequently asked questions about reflective road signs.

  • 3M™ Diamond Grade™ reflective sheeting (DG³) meets Class RA3 and R3B of DIN 67520 and Class R3C-UK of UK National Annex to EN 12899-1. This highly reflective sheeting uses 100% efficient full-cube prismatic technology that reflects, almost twice the amount of light back to its source as High Intensity Prismatic sheeting.
  • This prismatic sheeting is commonly made using truncated cube corner technology. It reflects more light than glass-bead technology found in some engineer grade sheeting. It provides an intermediate retroreflection and performs best at best at short distances.
  • Of the three technologies used on roadways today, only full cube microprismatic sheeting is the most efficient. The full cube technology in 3M™ Diamond Grade™ DG³ Reflective Sheeting make signage brighter and visible at greater distances. This gives drivers of all vehicle types more time to react.
