A speed limiter is a device designed to restrict the maximum speed of a vehicle. It plays a key role in reducing accidents and fuel usage by ensuring drivers stay within legal speed limits. From 2022, Intelligent Speed Assistance (ISA) technology has made these systems smarter and more effective, especially for fleet vehicles.

How Do Speed Limiters Work?

Modern speed limiters like ISA use GPS data and traffic sign recognition cameras to determine the legal speed limit in an area. If a vehicle exceeds that limit, the system issues an audible warning and restricts fuel flow to reduce speed.

While drivers can temporarily override the limiter by pressing firmly on the accelerator, the system encourages safer driving and helps businesses stay compliant with UK speed limiter regulations.

What Are the UK Speed Limiter Regulations?

As of 6 July 2022, all new vehicles sold in the UK must include a speed limiter as standard. The European Commission’s rules also apply to models previously launched, with a deadline of July 2024 for retrofitting the technology.

These changes mark a major shift in road safety legislation and highlight the importance for businesses to understand and embrace this technology. You can learn more about the legal side in this Fleet News article.

Can You Remove a Speed Limiter?

Technically, yes, it is possible to remove or bypass a speed limiter, especially older models. However, tampering with speed-limiting devices could invalidate your vehicle insurance and potentially breach road safety laws.

Businesses should avoid any attempts to remove or disable speed limiters. The long-term benefits of improved fuel efficiency and driver safety far outweigh the temporary speed gains. For further reading, check out We Buy Any Car’s guide.

Speed Limiters vs. Cruise Control

Though similar in concept, speed limiters and cruise control serve different purposes. Cruise control maintains a steady pace without driver input, ideal for motorway driving. Speed limiters, however, allow full control of acceleration and braking, up to a maximum speed.

For a simple comparison, Carwow’s article breaks down the pros and cons of both systems.

Benefits of Speed Limiters for Fleets

There are many reasons to embrace speed limiters across your fleet:

  • Improved road safety: The European Transport Safety Council estimates a 30% reduction in collisions.
  • Lower insurance premiums: Fewer speeding fines and penalty points may help reduce insurance costs.
  • Fuel savings: Driving at lower speeds can cut fuel use by up to 40%, according to research from Cobra UK.
  • Reduced emissions: Slower speeds = less CO₂ essential for any business targeting sustainability.
  • Enhanced company image: Responsible driving reflects well on your brand, especially in branded vehicles.

How Speed Limiters Affect Your Business

Adapting to speed limiters may require operational changes, especially for fleets that travel long distances. While journey times may slightly increase, the benefits to safety, cost control, and emissions reduction far outweigh the drawbacks.

Fleet managers should present this technology positively, reinforcing that speed limiters are an asset, not a barrier. They support responsible driving and protect your brand’s reputation on the road.

If you’re still wondering when you should allow for the effects of a speed limiter, the answer is now. Preparing your drivers for ISA systems and reviewing routes or delivery timelines will ensure a smooth transition.
