COMMISSION DELEGATED REGULATION (EU) …/...  
of XXX  
supplementing Regulation (EU) 2019/2144 of the European Parliament and of the 
Council by laying down detailed rules concerning the specific test procedures and 
technical requirements for the type -approval of motor vehicles with regard to their 
intelligent speed assistance systems and for the type -approval of those systems as 
separate technical units and amending Annex II to that Regulation  
(Text with EEA relevance)   EN 1  EN EXPLANATORY MEMORANDUM  
1. CONTEXT  OF THE  DELEGATED  ACT  
Regulation (EU) 201 9/2144 of the European Parliament and of the Council1 mandates motor 
vehicles of categories M and N to be equipped with intelligent speed assistance (ISA) systems 
from 6 July 2022 for new vehicle types and from 7 July 2024 for all new vehicles.  
There were  close to  23 000 fatalities in 2019  on EU roads. Drivi ng at excessive or 
inappropriate speed is a major threat to safety on the road. It is estimated that 10 to 15% of all 
crashes and 30% of all fatal crashes are the direct result of speeding or inappropriate speed2. 
Technical solution s assisting drivers in r educing driving speed can have profound impact on 
accident outcome and reduction of injury levels.  
The Intelligent Speed Assistance (ISA) is a system  that prompts and encourages drivers to 
slow down when they are over the speed limit. The system works with  the driver as an 
assisting function, through the accelerator control, or through other dedicated, appropriate and 
effective feedback, while the driver is always in full control of the driving speed of the 
vehicle. It is an effective safety measure because  even a slightly reduced driving speed has a 
significant beneficial effect on accident avoidance or mitigation of the accident outcome.  
The Commission is empowered to lay down detailed rules concerning the specific test 
procedures and technical requirement s for the type-approval of motor vehicles with regard to 
the intelligent speed assistance systems as well as for the type -approval of those systems as 
separate technical units. This Commission Delegated Regulation supplements Regulation 
(EU) 201 9/2144 by l aying down the respective technical requirements and test procedures . 
2. CONSULTATIONS  PRIOR  TO THE  ADOPTION  OF THE  ACT  
In the preparation of this act, the Commission carried out appropriate consultations with the 
Member States experts  and stakeholders. Ex change of views on the approach proposed took 
place at the meetings of the Motor Vehicle Working Group held on 8 July, 8 October, 9 
November ( ad hoc ) and 16 December 2020, as well as at  the meeting of the Member States 
Expert Group on 18 January 2021 .  
The questions raised at the consultation process related to  the effectiveness of the ISA 
cascaded acoustic warning function (one of the four options proposed in the draft)  and its 
potential  for annoyance to drivers  in real -driving conditions ; the level of the performance rate  
requirements for ISA systems,  which can be particularly challenging with regard to the 
compliance of ISA systems with the implicit road signs; the status of vehicles fitted with  ISA 
systems deployed before the adoption of Regu lation (EU) 2019/2144  and not fully in 
compliance with the technical requirements under this Delegated Regulation . 
The draft Commission Delegated Regulation addresses to the extent possible the concerns 
raised in the consultation and it  is generally  suppor ted by the EU Member States and 
stakeholders.  
3. LEGAL  ELEMENTS  OF THE  DELEGATED  ACT  
The legal basis of this delegated act is Article 4(6) and  Article 6(6) of Regulation (EU) 
2019/2144  of the European Parliament and of the Council . 
                                                 
1 OJ L 325, 16.12.2019,  p. 1. 
2 https://ec.europa.eu/transport/road_safety/sites/roadsafety/files/pdf/2020 -10-08-road_safety_thematic_report_speed.pdf  EN 2  EN ISA systems have to provide feedback to the driver in case of over -speed conditions, which 
has to be appropriate and effective. As the current development of technology stands, there 
are several technical options for the feedback  methodology . However, not all of them can be 
used in each and every motor vehicle  (it depends on the engine, the propulsion type (hybrid), 
the gearbox, etc. ). Therefore, it is provided in the draft Delegated Regulation that vehicle 
manufacturers can choose one of the following four feedback methodologies to base their ISA 
systems on : 
(1) the haptic feedback system which relies on the pedal restoring force : 
– Driver’s foot will be gently pushed back in case of over -speed. It will help to reduce 
driving speed  and can be overridden by the dr iver. 
(2) the speed control system which relies on engine management : 
– Automatic reduction of the propulsion power independent of  the position of drive’s 
feet on the pedal , but that can also be overridden by the driver  easily . 
(3) the c ascaded acoustic warning : 
– 1st step: flash an optical signal  
– 2nd step: after several seconds, if no reaction from the driver, the acoustic warning 
will be activated  
– If the driver ignores this combined feedback, both warnings will be timed -out. 
(4) the c ascaded vibration warning  
– 1st step: f lash an optical signal  
– 2nd step: after several seconds, if no reaction from the driver, pedal will vibrate   
– If the driver ignores this combined feedback, both warnings will be timed -out. 
Despite the functional differences, ISA systems based on each of those four options are 
considered equally safe and effective.  
The basic speed limit information system (SLI - visual warning only), which is a technology 
available in some motor vehicles today,  is estimated to be 20% less effective due to missed 
visual  alerts by drivers . For this reason it is considered not sufficiently effective or appropriate 
to be provided as a  feedback technology  alone,  in this Regulation .  
Acoustic warning on the other hand is shown to be very effective in terms of driver reaction, 
but it is deemed annoying.  
Annoyance is an important element regarding the choice of technology. For this reason, t he 
cascaded acoustic warning option  combines f or each over -speeding event the non -annoying, 
but less effective, optical signal with the acoustic warning as a back -up. To make sure the 
warning does not become unappreciated, its duration is kept short. Hence, it  is designed in 
such a way to mitigat e annoyance appropriately.  
At this stage, there is no conclusive evidence as to which of the four proposed feedback 
technologies  will be significantly more effective or less annoying in real -world driving 
conditions  in the EU . All the presently available and re viewed research on effectiveness and 
annoyance, including on the warning sound , reflects primarily  laboratory  based  simulation 
testing and not the real -world performance , as those  EU ISA compliant  systems will only be 
deployed in motor vehicles as of now.  
The effectiveness and reliability of the different  ISA systems have to be assessed once 
sufficient number of motor vehicles equipped with such systems have been place d on the EN 3  EN market and the relevant real-life expe rience is available. It  is also essential that such 
evaluation is made as soon as possible and , if necessary, the requirements in this Commission 
Delegated Regulation are amended ac cordingly . It is pro vided  that the Commission assess the 
effectiveness of the ISA systems by 31 December 2025 ( which is earlier than the overall 
review foreseen in Article 14 of Regulation (EU) 2019/2144 by July 2027) on the basis of the 
information to be provided by the vehicle manufacturers and approval authorities of the EU 
Member States.  
For the purposes of testing t he real -world performance of the ISA systems, a n exhaustive  
catalogue of signs by country is included in the Annexes to this Regulation .  
The provisions of this Commission Delegated Regulation will apply from the date of 
application of Regulation (EU) 2019 /2144 . 
This Commission Delegated Regulation also amends Annex II to Regulation (EU) 2019/2144 
by adding a reference to the regulatory act establishing the specific requirements with regard 
to the intelligent speed assistance systems.  EN 4  EN COMMISSION DELEGATED REGULATION (EU) …/...

THE EUROPEAN COMMISSION,  
Having regard to the Treaty on the Functioning of the European Union , 
Having regard to  Regulation (EU) 2019/2144 of the European Parliament and of the Council 
of 27 November 2019 on type -approval requirements for motor vehicles and their trailers, and 
systems, components and separate technical units intended for such vehicles, as regards their 
general safety and the protection of vehicle occupants and vulnerable road users, amending 
Regulation (EU) 2018/858 of the European Parliament and of the Council and repealing 
Regulations (EC) No 78/2009, (EC) No 79/2009 and (EC) No 661/2009 of the European 
Parliament and of the Council and Commission Regulations (EC) No 631/200 9, (EU) No

(EU) 2015/1661, and in particular Article 4(6) and Article 6(6)  thereof,  
Whereas:  
(1) Article 6 of Regulation (EU) 2019/2144 requires motor vehicles of categories M and 
N to be equipped with certain advanced vehicle systems, including intelligent speed 
assistance (‘ISA’) systems. Annex II to Regulation (EU ) 2019/2144  lays down basic 
requirements for the type -approval of motor vehicles with regard to the ISA systems . 
(2) Detailed rules are necessary concerning the specific test procedures and technical 
requirements for  the type -approval of motor vehicles with regard to ISA systems as 
well as for the type -approval of those systems as separate technical units .  
(3) In accordance with Article 3, point (3), of Regulation (EU) 2019/2144 the ISA system 
is a system to aid the driver in maintaining the approp riate speed for the road 
environment by providing dedicated and appropriate feedback . Currently there are 
several technical options for the feedback methodology  to be used as a basis for an 
ISA system . However, not all of those options can be used in each motor vehicle. It is 
therefore, necessary to specify  feedback methodologies that are equally safe and 
effective  despite their functional differences. I t is appropriate to specify several 
feedback methodologies and allow the manufacturers to choose any of t hose 
methodologies to base their ISA systems on . 
                                                 
1 OJ L 325, 16.12.2019,  p. 1.  EN 5  EN (4) The ISA system may rely on various input methods, such as  camera observation, map 
data and deep learning, however, the actual presence  of real -world speed limit related 
signs should always take precedence over any other available and potentially diverging 
information.  
(5) For the purpose s of testing the real -world performance of the ISA system, it is 
necessary to establish an exhaustive  catalogue of road signs  used in each Member 
State.  
(6) The ISA s ystems may be faced with ambiguous speed related information due to 
missing, vandalised, manipulated or otherwise damaged signs, erroneous sign 
placement, inclement weather conditions or non -harmonise d, complicated and implicit 
speed restrictions. For this reason , the underlying principle should be that the driver is 
always responsible for adhering to the relevant traffic rules and that the ISA system is 
a best -effort driver  assistance system  to alert the driver , when ever possible and 
appropriate.  
(7) The specific test procedures and technical requirements for the ISA systems should be 
to the greatest extent technology neutral and performance -based  to allow innovative 
solutions.  
(8) The specific test procedures and technical requirements for the  ISA systems should 
also ensure that a system does not exceed the capability of an average  human driver of 
interpreting and understanding the pertinent speed limit information . ISA systems 
should no t be required to have self -driving levels of capability, but only provide 
assistance to  driver s. 
(9) The assessment of the effectiveness of the different feedback methodologies  and 
control functions  of the ISA systems in real -drive conditions will only be poss ible 
once  a significant number of motor vehicles equipped  with such systems  are available 
on the market . On other hand, it is essential t hat such assessment is carried out without 
delay in order to reap all the potential road safety benefits of the ISA systems . The 
relevant technologies and real-drive experience  is expected to be available by 31 
December 2025, thus well in advance of the date for the overall review set out in 
Article 14 of Regulation (EU) 2019/2144 . In order to enable the Commission to 
evaluate  the performance of the feedback methodologies  provided for by this 
Regulation  as early as possible , it is necessary to require the manufactures to provide 
the relevant information to the approval authorities and for the approval authorities to 
aggregate that information and provide it to the Commission . 
(10) In order to minimise distracting or overloading drivers with false warnings caused  by 
sub-optimal systems  in the real -world, it is necessary to ensure that vehicle 
manufacturers employ appropriate technologies in the vehicle fleet and that 
manufacturers provide , where appropriate and necessary for a reasonable proportion of 
the vehicle’s life -time, an unrestricted  and easy access to system updates . 
(11) It is however clear that systems employing a combination of a camera system , Global 
Navigation Satellite System (GNSS) and up-to-date digital maps are considered the 
state of the art systems with the greatest real -world performance and reliability . 
(12) The t able in Annex II to Regulation (EU) 2019/2144  containing the list of 
requirements referred to in Article 4(5) and Article 5(3)  of that Regulation  does not 
contain any reference to regulatory acts as regards intelligent speed assistance systems . 
It is there fore necessary to add a reference to this Regulation in that Annex .  
(13) Regulation (EU) 2019/2144  should therefore be amended accordingly.  EN 6  EN (14) As Regulation (EU) 2019/2144 is to apply from 6 July 2022, this Regulation should 
apply f rom the same date.  
(15) The provisions of this Regulation are closely linked, as they deal with rules concerning 
the specific test procedures and technical requirements for the type -approval of motor 
vehicles with regard to the ir intelligent speed assistance systems  and for the t ype-
approval of those systems as separate technical units . As a result of the rules laid down 
in this Regulation, it is necessary to add a reference to this Regulation in Annex II to 
Regulation (EU) 2019/2144 . It is therefore appropriate to lay down those provisions in 
a single Delegated Regulation ,
