UK's Speed Limits And The Future Of Speed Limiters

In the ever-evolving landscape of road safety, the United Kingdom has implemented new measures aimed at reducing accidents and promoting safer driving practices. Central to these efforts are the revised speed limits for vehicles on the road and the incorporation of speed limiters in cars. In this article, we delve into the intricacies of these regulations, exploring how they work and their significance in enhancing road safety.

New Speed Limits: Keeping Pace with Safety

Speed limits serve as crucial guidelines for drivers, ensuring that they operate their vehicles at safe and manageable speeds. The UK government periodically reviews and updates these limits to align with advancements in vehicle technology and evolving road conditions. In recent years, there have been notable revisions to speed limits across various types of roads, reflecting a concerted effort to enhance road safety.

Motorways: Raising the Bar

One of the significant changes in the UK's speed limits pertains to motorways. Historically capped at 70 miles per hour (mph), the maximum speed limit on some sections of motorways has been increased to 80mph, subject to certain conditions. This adjustment aims to accommodate the improved safety features of modern vehicles and the enhanced infrastructure of motorways while maintaining a focus on safety.

Rural Roads: Exercising Caution

In contrast, speed limits on rural roads, where hazards such as sharp bends and limited visibility are prevalent, have been subject to stricter regulations. Reduced speed limits, often as low as 50 mph or even lower in certain areas, underscore the importance of exercising caution and adapting driving speeds to the prevailing road conditions.

Urban Areas: Prioritising Pedestrian Safety

Within urban areas, where road congestion and pedestrian activity are more pronounced, speed limits typically range between 20 mph and 30 mph (in Wales this is now 20mph countrywide). These limits prioritise pedestrian safety and aim to mitigate the severity of accidents in densely populated areas.

Speed Limiters: A Technological Frontier in Road Safety

In addition to revised speed limits, another noteworthy development in the realm of road safety is the integration of speed limiters in vehicles. Speed limiters, also known as intelligent speed assistance (ISA) systems, represent a technological innovation designed to curb instances of speeding and promote adherence to speed limits. In terms of the law, all new cars have to be fitted with speed limiters and have been since July 6th 2022. Whilst this was a European rule, it was ratified and incorporated into UK law too. Showrooms from the 6th July 2024 have to ensure all cars have speed limiters in them when sold which will have an impact on the cost of vehicles sold too.

How Speed Limiters Work

Speed limiters operate by utilising a combination of GPS technology, just like our vehicle trackers and onboard sensors to detect the vehicle's speed and location. Once activated, the system monitors the prevailing speed limit for the road on which the vehicle is travelling. If the vehicle exceeds the designated speed limit, the speed limiter intervenes by restricting the engine power or applying brakes, thereby ensuring compliance with the prescribed speed limit.

The Benefits of Speed Limiters

The integration of speed limiters in vehicles offers multifaceted benefits in terms of road safety and environmental conservation. By enforcing adherence to speed limits, these systems help mitigate the risk of accidents caused by speeding, thereby reducing the incidence of injuries and fatalities on the road. Moreover, by promoting smoother and more consistent driving speeds, speed limiters contribute to improved fuel efficiency and reduced emissions, aligning with broader sustainability objectives.

Regulatory Landscape and Implementation

Recognising the potential of speed limiters to enhance road safety, regulatory bodies in the UK have taken proactive steps to encourage their adoption. While the installation of speed limiters in new vehicles has become increasingly commonplace, there are ongoing discussions regarding the feasibility and implications of retrofitting existing vehicles with these systems. Moreover, there are considerations surrounding the calibration and customisation of speed limiters to accommodate varying driving conditions and individual preferences.

Conclusion: Navigating Towards Safer Roads

As the UK continues its journey towards safer and more sustainable transportation systems, the implementation of revised speed limits and the integration of speed limiters represent pivotal milestones in this endeavour. By aligning regulatory frameworks with technological innovations, policymakers and stakeholders are collectively shaping a future where road safety is paramount, and drivers are empowered to make informed and responsible choices behind the wheel. As we embrace these advancements, let us navigate the roads with vigilance, consideration, and a shared commitment to fostering safer journeys for all. Please do note that whilst limiters are require to be present, they do not have to be activated but in the interests of ensuring your workforce to not break the law and is more likely to drive safely, activating them could also help with lowering fuel costs. Flexibility in some limiters will also mean that they do not always slow down towards the limit, with some still allowing speed increases if the accelerator pedal is depressed hard enough. 

A Reminder of the current laws around speeding limits:
 

National speed limits

The following speed limits apply to all single and dual carriageways with street lights unless there are signs showing otherwise:

  • 30 miles per hour (48km/h) in England, Scotland or Northern Ireland
  • 20 miles per hour (32km/h) in Wales

Speed limits on single and dual carriageways and motorways

Vans, car-derived vans and dual-purpose vehicles

Most vans:

  • Have a lower speed limit than cars
  • Must follow the speed limits for goods vehicles of the same weight

Vehicles under 2 tonnes laden (loaded) weight may qualify as a car-derived van’ or ‘dual-purpose vehicle. These vehicles have the same speed limits as cars.

Motorhomes

Motorhomes or motor caravans are classed as goods vehicles if they:

  • carry goods for exhibition and sale
  • are used as a workshop
  • are used for storage

Locally set speed limits

Local councils can set their own speed limits in certain areas, and these must be clearly signed.

For example:

  • 20mph zone in a built-up area near a school
  • 50mph (rather than 60mph) limit on a stretch of road with sharp bends

Speed limiters

A speed limiter must be fitted on:

  • vehicles with more than 8 passenger seats, for example, buses, minibuses, coaches, stretch limousines
  • goods vehicles with a maximum laden weight of more than 3.5 tonnes

Speed limiters are designed to reduce collisions. They limit the maximum speed of a vehicle by restricting the fuel supply to the engine. Having a speed limiter may mean that your vehicle cannot reach the speed limit.
