On July 1st, 2024, the United Kingdom officially adopted a significant new regulation impacting all new cars: mandatory Intelligent Speed Assist (ISA) systems. This move aligns the UK with European Union laws, reflecting the continued influence of EU standards on UK legislation even post-Brexit. The implementation of speed limiters is poised to revolutionize driving practices, aiming to enhance road safety and reduce traffic collisions.

The Mechanism Behind Speed Limiters

The newly mandated ISA systems are designed to prevent drivers from exceeding speed limits. These systems can operate using one of three methods:

  1. Advisory ISA: This system provides a warning to the driver when the speed limit is exceeded, typically through visual or auditory alerts.

  2. Supportive ISA: This method increases resistance on the accelerator pedal, making it physically more challenging to speed.

  3. Mandatory Speed Assist: This system actively reduces engine power to ensure the vehicle complies with the speed limit, allowing for a gradual reduction in speed.

The technology employed by these systems relies on either cameras that detect traffic signs or GPS data that correlates the vehicle's location with local speed limits. In some instances, both technologies are used in tandem to ensure accuracy.

Implications for UK Drivers

The introduction of speed limiters is expected to be met with mixed reactions. While the primary goal is to enhance safety, many drivers may view this as an encroachment on their driving freedom. Government research highlights the extent of speeding on UK roads, with 45% of motorists exceeding limits on motorways and 50% doing so on 30mph roads. The pervasive belief in a 10% speed cushion has further normalized this behaviour.

Despite potential resistance, safety experts argue that these measures will significantly reduce traffic collisions and related fatalities. The European Commission projects that intelligent speed assistance, along with other advanced safety features, could help avoid 140,000 serious injuries by 2038 and ultimately aim to eliminate road deaths by 2050.

Deactivation and Compliance

While drivers can deactivate the mandatory speed limiter, it will reset with each restart of the vehicle. Overriding the system by forcefully pressing the accelerator remains an option, albeit an illegal one. Importantly, the ISA system's data is recorded and can be accessed by insurers or authorities in the event of an accident, potentially influencing insurance claims and legal consequences.

Broader Safety Measures

The mandate for speed limiters is part of a broader suite of safety measures approved by the European Commission, including advanced emergency braking and lane-keeping technology. These initiatives reflect a comprehensive strategy to improve road safety across Europe, with the UK actively participating despite its departure from the EU.

Reception and Criticism

The reception of speed limiters has been varied. Road safety advocates, such as the charity Brake, have hailed the measure as a landmark advancement for road safety, potentially saving thousands of lives. The UK's Department for Transport supports the move, anticipating a significant positive impact on road safety.

Conversely, critics argue that such technology could inadvertently lead to more reckless driving behaviours. The AA, for instance, contends that while autonomous emergency braking has clear benefits, intelligent speed adaptation might not be as effective. They argue that drivers may rely excessively on the system, potentially driving at the maximum allowable speed even in situations where lower speeds are warranted, such as near schools.

The adoption of Intelligent Speed Assist systems marks a pivotal moment in UK road safety policy, aligning the country with broader European safety standards. While the technology aims to reduce accidents and save lives, its real-world impact will depend on how drivers adapt to and accept these new regulations. As this law comes into force, the UK stands on the cusp of a significant transformation in driving culture and road safety.
