Speed Limiter (Speed Governor) Installation in Kenya
NTSA-Compliant Speed Governor Fitting & Calibration.
Crescent Systems Kenya fits speed governors for PSVs and commercial vehicles in line with Kenya’s speed governor requirements under KS 2295:2018. We handle the full installation, calibration, certification, and NTSA registration process.
Who Legally Needs a Speed Governor
- Public Service Vehicles (PSVs) — buses, matatus, and any vehicle carrying passengers for hire, generally from 7 seats and above.
- Commercial vehicles — at or above 3,048 kg (gross vehicle weight).
- Enforced speed cap: 80 km/h for both categories under the Traffic Act.
What the Standard Requires (KS 2295:2018)
Kenya’s speed governor requirements are set under KS 2295:2018 (Parts 1 and 2). Compliant devices must:
- Store trip data for a minimum of 72 hours
- Transmit speed readings every 5 seconds to NTSA’s Intelligent Road Safety Management System (IRSMS)
What’s Changing for 2026 (Cross-Border Fleets)
Kenya, Ethiopia, and Rwanda are moving toward R89-certified, GPS-enabled devices for cross-border fleet compliance. If your vehicles operate routes beyond Kenya’s borders, this is a critical development to plan for.
How Our Installation & Certification Works
- Vehicle assessment – category and weight-class verification
- Fitting – wiring into the engine/transmission system
- Calibration – set to the legally required 80 km/h speed cap
- Tamper-evident sealing & certificate – we issue a calibration certificate for your records
- NTSA IRSMS registration – we register the installation with NTSA so your vehicle is fully compliant for inspection
Frequently Asked Questions
Is a speed governor required for my matatu?
Yes, if it seats 7 or more passengers and operates as a PSV.
Does my delivery truck need one?
Yes, if its gross vehicle weight is at or above 3,048 kg, regardless of whether it carries passengers.
How often does it need recalibration?
Kenya does not mandate a fixed annual recalibration cycle for an unmodified, functioning installation. However, recalibration is required any time the device is reinstalled, repaired, or replaced. Annual checks are widely recommended as best practice to ensure continued accuracy.
What happens if I skip it or let it lapse?
The vehicle cannot renew its Certificate of Fitness. Non-compliant vehicles risk fines and impoundment at NTSA checkpoints.
