Speed Limiter Device
Boost road safety with our R89 certified Speed Limiter Device—your smart solution to stop dangerous speeding before it happens. With GPS speed control, overspeed alarm, and forced speed limiting, it keeps every vehicle at a safe, controlled speed. Reliable, anti-vibration, and easy to install, this speed limiter device protects drivers, fleets, and your business.
Smart Control for Safer Driving
Stop Deadly Speeding Before It Starts — With a Smart Speed Limiter Device
Every year, most road accidents come from one simple cause: speeding rear-end collisions. Studies show that over 60% of these crashes are caused by vehicles driving too fast. Minor accidents waste time, energy, and money. Major accidents can cost lives.
Installing a speed limiter device is like adding a personal safety manager to every vehicle you operate.
Smart Technology Built to Keep Every Trip Safe
Our advanced speed limiter device integrates multiple protective features designed for modern fleets and private vehicles:
Remote configuration for easy setup
Real-time speed display
Overspeed alarm + forced speed limiting
Accurate speed control within ±5 km/h
GPS-based speed monitoring
Strong anti-vibration metal housing with a compact, stylish design
Suitable for trucks, buses, school buses, public transport, commercial fleets, and cars.
Precision Control That Prevents Speeding — Automatically
When the vehicle reaches the preset maximum speed, the speed limiter device automatically controls the throttle and activates forced speed limiting.
Powered by GPS high-precision speed detection, the system supports mechanical and electronic throttle control, ensuring consistent and stable limiting even on long trips and rough roads.
Built with a full-floating anti-shock structure and robust environmental resistance, it performs reliably under all driving conditions.
