What is BS EN 12899-1:2015? .


In the field of transportation infrastructure, road markings play a vital role in ensuring road safety and providing clear guidance to drivers. To guarantee uniformity and standards across Europe, the British Standards Institution (BSI) has developed the BS EN 12899-1:2015 standard. This article aims to explain what BS EN 12899-1:2015 entails and why it is significant in the road marking industry.

The Purpose of BS EN 12899-1:2015

BS EN 12899-1:2015 is a European standard that specifies the requirements for road traffic signs, including permanent road markings. It defines the materials, dimensions, reflectivity, and performance criteria for various types of road markings. The primary purpose of this standard is to ensure consistency in road markings, enabling drivers to easily understand and perceive them regardless of their location within Europe.

Main Features of BS EN 12899-1:2015

BS EN 12899-1:2015 covers several key aspects related to road markings. One essential feature is the classification of road markings based on performance levels, ranging from high performance (Category REF-I) to normal performance (Category REF-IV). These classifications consider attributes like retroreflectivity, durability, skid resistance, and chromaticity. By standardizing these levels, the standard ensures that road markings meet specific visibility and quality standards.

Another significant aspect of BS EN 12899-1:2015 is the requirements for road marking materials. The standard includes guidelines on the color and contrast of road markings, the use of additives for improved retroreflectivity, and even the curing time necessary for thermoplastic road markings. These guidelines further contribute to ensuring the longevity and visibility of road markings, allowing drivers to rely on them for safe navigation.

Implementation and Benefits

Since its introduction, BS EN 12899-1:2015 has been widely implemented by road authorities and highway maintenance teams across Europe. Compliance with this standard offers numerous benefits. Firstly, it enhances road safety by providing consistent, visible, and durable road markings that help drivers navigate roads more effectively.

The standard also aids in cost-effective maintenance planning by establishing performance requirements for road markings. By adhering to specific durability and retroreflectivity criteria, road authorities can predict when maintenance or replacement is required, resulting in better budget management and improved overall road infrastructure quality.

Moreover, BS EN 12899-1:2015 enables cross-border harmonization of road markings throughout Europe. This facilitates international travel by ensuring that drivers from different countries can easily understand and follow road signage across borders.


In conclusion, BS EN 12899-1:2015 establishes the standards and requirements for road traffic signs, specifically permanent road markings, in Europe. It covers various aspects such as material specifications, performance levels, and classification criteria. Implementation of this standard leads to improved road safety, efficient maintenance planning, and harmonized road markings across European borders. As a result, drivers can confidently rely on these standardized road markings for clear guidance and enhanced road navigation.
