ESS Mandatory from July: The Revolutionary Braking System for All New Registrations

The European Union has expanded regulations dedicated to road safety, and from July 7, 2026, the presence of the Emergency Stop Signal (ESS) will be mandatory on all newly registered vehicles. This measure is part of EU Regulation 2019/2144 and aims to reduce the number of rear-end collisions, which still represent one of the most frequent types of accidents on European roads.

The new requirement applies only to vehicles registered for the first time after the regulation comes into force. Cars already in circulation, as well as those purchased before the deadline, will not need to be updated or retrofitted.

From a technical perspective, the Emergency Stop Signal activates only during an emergency braking situation. The system is triggered when the vehicle is traveling at a speed above 50 km/h and registers a deceleration greater than 6 m/s². In this situation, the brake lights begin to flash rapidly, and on some models, the hazard lights (four-way flashers) may also be activated, thereby increasing the vehicle's visibility to following drivers.

The activation occurs thanks to data collected by the on-board electronics, which monitors in real-time the information from the ABS, the pressure applied to the brake pedal, and the vehicle's speed. The principle behind the system is simple: a flashing light signal is perceived more quickly than a steady light, with a reaction time advantage that can translate into approximately 4.5 meters of additional braking distance, sufficient in many cases to avoid an impact or, at least, to minimize its consequences.

The ESS is one of the elements of the driving assistance device package stipulated by European regulations. Following the introduction of mandatory ADAS for new approvals in 2024, from July 2026, the same requirements will be extended to all new registrations, including those based on previous approvals.

In addition to the Emergency Stop Signal, new cars will need to integrate a driver fatigue detection system, capable of identifying signs of fatigue or loss of concentration and suggesting a break. Lane Departure Warning, Lane Keep Assist, and especially Emergency Lane Keeping, designed to intervene in high-risk situations, will also be mandatory.

Other required devices include a rearview camera or sensors dedicated to detecting pedestrians, cyclists, and other vehicles during reverse maneuvers, as well as Automatic Emergency Braking (AEB), which uses radar, cameras, and sensors to identify obstacles and automatically reduce speed or stop the vehicle when necessary.

The regulation also confirms the adoption of the Event Data Recorder (EDR), the so-called black box, which will record essential data in the event of an accident. From 2026, the obligation will also be extended to newly registered trucks and buses.

Among the proposed technologies is the Intelligent Speed Assist (ISA), which compares speed limits detected through sign recognition and GPS data, warning the driver when they exceed the allowed limit. All new vehicles will also need to be prepared for the installation of an alcolock, although the device will not be mounted as standard.

Naturally, the introduction of these systems as mandatory, according to some observers, increases vehicle complexity and inevitably also its cost. However, the EU believes that road safety takes precedence, so no extensions or exemptions are planned on this front.
