Closed lane sign 90x135 cm Class 1 Fig. 411/g Galvanised steel sheet

Closed Lanes Signplate (Fig. 411/g) Class 1: Temporary Road Safety

The "Closed Lane Sign" plate, identified with Figure 411/g and compliant with Class 1 reflectivity, is a crucial element for traffic management and safety in road environments. With its increased dimensions of 90x135 cm, it is designed to ensure maximum visibility and clarity in situations of temporary signage, such as construction sites, accidents or detours on motorways and main extra-urban roads. Its function is to unequivocally indicate the lanes no longer available for transit, directing road users into safe routes.

Technical Characteristics and Resilient Materials

This plate is made of galvanized steel sheet with a thickness of 12/10 mm, a material that ensures strength and resistance to atmospheric agents. The perimeter is finished with a folded, cut-resistant edging, for greater safety during handling and installation. The back of the license plate is painted rust-proof and prepared for easy attachment to trestles or other supports, offering mounting versatility. Class 1 reflectivity guarantees standard visibility, ideal for urban or temporary contexts with normal visibility and low transit speeds, in full compliance with the UNI EN 12899-1 standard.

Visual Clarity and Strategic Applications

The signal design is designed for immediate understanding. It has a bright yellow background, the conventional color for temporary signs, on which a blue box with white arrows indicating lanes open to traffic stands out. Closed lanes are clearly marked with a red X, making communication immediate and unambiguous. This sign is indispensable for temporary signage on motorways and main country roads, especially in the event of partial closure of the carriageway for road works, emergency situations such as accidents or for the management of detours. Its installation at a warning distance (generally 150-250 meters from the point of interference) allows motorists to anticipate changes in traffic flow.

FAQ on the Closed Lane Signal Plate (Fig. 411/g)

What is the purpose of the "Lane Closed Sign" sign (Fig. 411/g)?

This license plate serves to inform drivers clearly and visually that certain lanes of a roadway are closed to traffic, indicating which ones remain open. It is critical to driving vehicular flow safely through work areas, accidents, or road diversions.

Where is this traffic sign typically used?

The closed lane sign (Fig. 411/g) is mainly used as temporary signage on motorways and main country roads. It is installed near road construction sites, in the event of partial closures of the carriageway for maintenance or emergencies, and to manage traffic diversions.

What are the main characteristics of Class 1 refractive for this signal?

Class 1 refractive indicates that the signal has a standard reflectivity, adequate for use in urban environments or temporary situations where visibility is normal and transit speeds are limited. It complies with the UNI EN 12899-1 standard and ensures that the signal is visible even in low light conditions thanks to the vehicle headlights.
