This Kenya Standard was developed by the Technical Committee on Extra -low Voltage Equipment under the 
guidance of the Standards Projects Committee (SPC) , and is in accordance with the procedures of the Kenya 
Bureau  of Standards . 
 
The first edition of this standard in 2011 was published as a way of minimiz ing accidents attributed to  speeding  
of PSVs and vehi cles with a tare weight exceeding 3048 Kg ( as per the Traffic Act (Cap 403 Laws of Kenya) ). 
Subsequent to  the publication and enforcement of t he standard, se veral emerging technological 
changes /challenges  have necessitated revision of some of the provisions of the standard . Tampering with the 
speed recorder required further measures to be prescribed in the se cond edition which resulted in among other 
requirements, requiring the speed to be tapped from the electromechanical speed sensor installed onto the 
speedometer cable take off at the gearbox or by use of the vehicle inbuilt speed sensor . This effectively barred 
the use of speed signals derived from either GPS or GPRS signals due to their unreliability and vulnerability 
to manipulation . Another critical addition to the second edition was the requirement for the mandatory  online 
reporting system  for all the speed data and any malfunction within the speed limiting function . 
 
A driver whose speed is no more than 80 Km/h is obviously far less likely to have an accident than the same 
driver under the same road conditions going 90, 100, or even 120 Km/h. The differential between his speed 
and that of other vehicles on the road, the distance needed to stop the car, etc. are all much less. Moreover, 
even if an accident does occur, it will almost always be less severe. An accident at 120 Km/h is about 225% 
as sev ere as one occurring at 80 Km/h, even though the first vehicle is traveling only 50% faster. This is 
because the severity of the accident is directly related to the kinetic energy of the vehicle, which in turn is 
proportional not to the speed but to the sq uare of the speed . 
 
This Kenya Standard specifies requirements for the performance and installation of devices designed to limit 
the maximum road speed of motor vehicles by control of engine power .  
 
This third edition cancels and replaces the second edition, KS 2295 -1:201 8, Maximum road speed limiters for 
motor vehicles  Part 1:  Performance and installation requirements  which has been technically and editorially 
revised  with the following as the most no table revisions:  
 
- Revision and addition of some definitions  
- Revision of text for clarity  
- Reference to compliance requirements where they were missing  
- Requirement for compliance to the Data Protection Act, 2019 (DPA)  
 
During  the preparation of the Standard, reference was made to the following documents:

requirements .

Part 1:  
 
Performance and installation requirements  
 
1 Scope  and field of application  
 
This Part 1 of this Kenya Standard specifies requirements for the performance and installation of devices 
designed to limit the maximum road speed of motor vehicles by control of engine power.  
 
This standard also specifies performance requirements of speed recording and reporting devices. This may 
be a separate unit to be installed on the vehicle as an add -on or on -board system built in the vehicle.  
 
This standard does n ot cover methods of test and procedure for type approval which are covered under KS 
2295 -2. The two parts of this standard cannot therefore be read in isolation.  
 
NOTE 1  unless otherwise referred to in clause 3, the device is referred to hereafter as the limiter.  
 
NOTE 2  Permitted tolerances of the system may allow the vehicle to exceed the set speed.
