It is technically possible to install a speed limit device in a car that restricts its speed to a predetermined limit. Such devices are commonly known as speed limiters or speed governors. They work by limiting the fuel flow or electronically controlling the engine's power output to prevent the vehicle from exceeding the set speed limit.
Many modern vehicles, especially commercial vehicles or fleet vehicles, already come equipped with speed limiters as a safety feature. They are often used to enforce speed restrictions for various reasons, such as compliance with local laws, reducing fuel consumption, or enhancing overall safety.
However, it's important to note that retrofitting a speed limiter to an existing vehicle may not be straightforward, and the feasibility will depend on several factors:
Vehicle Compatibility: The installation of a speed limiter might require specific vehicle models or electronic systems that support such modifications. It may not be possible or practical for all vehicles, especially older models or those without the necessary electronic controls.
Technical Expertise: Installing a speed limit device requires technical expertise and knowledge of the vehicle's electronic systems. It's generally recommended to have the device installed by a qualified professional who understands the vehicle's wiring, engine management, and control systems.
Legal Considerations: The legality of retrofitting a speed limiter varies by jurisdiction. Some countries or regions may have regulations in place regarding the use and installation of such devices. It's important to research and comply with the specific laws and regulations applicable to your location.
Overriding or Tampering: It's worth noting that determined individuals might attempt to tamper with or override the speed limiter, potentially compromising its effectiveness. Ensuring the integrity of the device and implementing safeguards against tampering are important considerations.
If you are considering installing a speed limiter on your vehicle, it's recommended to consult with a professional installer or contact the appropriate authorities in your jurisdiction to understand the specific requirements, regulations, and feasibility for your situation.
