RetroSign GRX retroreflectometer
Safe traffic flow is highly dependent on the quality of road traffic signs and road markings. When driving at night-time on dark roads, retroreflection of road traffic signs and road markings is essential to assist drivers in keeping their vehicles safely positioned on the roads.
