How many cats eyes are generally placed on hazard lines?

The placement of cats' eyes, or road studs, on hazard lines is designed to enhance road safety by improving visibility for drivers. Generally, it is standard practice to place one cats' eye in every gap along the hazard lines. This spacing ensures that the road delineation remains clear and visible at night or during poor weather conditions, thereby aiding in navigation and increasing awareness of potential hazards.

By having a cats' eye in every gap, it provides continuous guidance to drivers, which is especially important in areas where driver attention is critical, such as near sharp turns, areas with high accident rates, or in poor visibility conditions. This systematic approach ensures that the hazard lines are not only visible but also effective in communicating important safety information to motorists.
