Which car makers WILL put automatic speed limiters in UK models this month? Each brand explains how to turn them off
- An EU mandate from 7 July 2024 requires all new cars to have speed limiters
- Same laws do not apply in Britain but major brands will still fit Intelligent Speed Assistance tech to new UK vehicles
- The 32 most popular manufacturers tell us how to turn off ISA in their models
A safety regulation mandate from the EU demands all car manufacturers fit speed limiters to new cars from this week – and the same technology will also be installed in almost all new models sold in Britain, we can exclusively reveal.
Despite the UK Government’s refusal to implement the same mandate, the most popular vehicle brands tell us they either already equip their latest models with Intelligent Speed Assistance (ISA), will do so from 7 July or plan to in the very near future.
Introduced in a bid to cut road deaths on Europe’s roads, the automatic speed limiter system uses a suite of tech in modern vehicles to determine the speed limit a car is travelling in.
If the driver is exceeding it, ISA will warn them to slow down and can even cut engine power.
We contacted the 32 top-selling brands in the UK in 2024 (which represent 98.9 per cent of the new car market) to find out if their UK models will be equipped with Intelligent Speed Assistance – and what is the protocol to turn it off before each journey.

What is Intelligent Speed Assistance?
Intelligent Speed Assistance uses a combination of GPS data, satellite navigation, speed-sign recognition cameras and forward-facing cameras to identify what the speed limit is at any given time and determine if the vehicle is exceeding it.
If the car is travelling over the limit, motorists will initially receive a number of warnings ushering them to slow down.
These can be visual alerts on the instrument cluster or screen, a short audible warning, or a gentle vibration of the steering wheel when the limit is being exceeded. Manufacturers can use a combination of these – or all three.

HOW THIS IS MONEY CAN HELP
If the alerts are repeatedly ignored by the driver, the system can intervene by restricting engine power to automatically bring the speed down to the legal limit.
At no time does ISA apply the brakes, achieving a reduction in speed only by curtailing the power from the engine.
ISA can be overridden for a short burst of acceleration above the legal speed limit, for instance when a driver needs to overtake a slow-moving vehicle.
To do so, the driver needs to push hard on the accelerator pedal to temporarily disengage the system. The ISA will allow the car to go above the permitted limit for a short amount of time before the alerts reengage.
Can Intelligent Speed Assistance be turned off?
Under the EU’s ‘GSR2’ or ‘Regulation (EU) 2019/2144’, ISA can be turned off. But not permanently.
The system must automatically activate each time the engine is started, meaning motorists will need to switch it off before setting off on every journey.
How difficult it is to deactivate the system is determined by each car brand. Mainstream manufacturers have explained below how to turn it off in their vehicles.
Do new cars sold in the UK also need to have Intelligent Speed Assistance by law?
ISA has been mandatory on all new cars introduced to European – and Northern Ireland – showrooms since 6 July 2022. This is only models that are brand new to the market.
However, the EU’s mandate dictates that from 7 July 2024 it will need to be retrofitted to all new vehicle sold in dealerships across the continent.

This means manufacturers will need to install the tech on some long-in-the-tooth models. For instance, Volkswagen will need to retrofit ISA into the existing Touran, which has been on sale since 2015.
But the same rules do not apply in Britain.
A spokesperson for the Department for Transport told This is Money it is currently not introducing the same regulation this month: ‘The Intelligent Speed Assistance laws coming into effect in July apply to the EU and Northern Ireland only, not Great Britain.’
This could all change, however, with a new Labour Government and transport ministers making such decision.
Experts have already warned UK drivers that they are unlikely to escape the technology because Britain is no longer part of the European Union.
Thatcham Research, the automotive risk intelligence company, explains: ‘Many vehicles sold in the UK will use EU specification software as manufacturers try to avoid the additional complexity of creating UK-specific variants, which increases the cost of bringing a vehicle to market.’
The AA, told us: ‘Even though ISA isn’t mandatory in the UK, many new cars will be sold with this technology’, while the RAC said it would ‘be surprised if manufacturers deliberately excluded the feature from those they sell in the UK as it would add unnecessary cost to production’.
And our exclusive report reveals these experts were accurate in their assumptions…
A-Z: Which car brands will have ISA in new UK cars?
We contacted the UK’s 32 biggest selling car brands – which represent 98.9 per cent of the new car market this year – asking if they are set to equip new UK models with ISA this month.
And we’ve also asked them to explain how to turn off the system in their vehicles.
Here’s what the most popular brands of 2024 told us…

Number of new cars sold in 2024: 65,317 (6.49% of the market)
Will UK cars have ISA from 7 July 2024? Audi is part of the Volkswagen Group. A spokesperson told us that some models across its different brands – which also includes VW, Skoda, Seat and Cupra – already have ISA, while others will ‘begin to adopt ISA as standard’ shortly. The tech will be ‘phased-in in-line with model updates, as soon as our factories implement the changes,’ they said.
How to turn off ISA: The feature can be turned off but the process ‘varies by model’. Volkswagen Group says in most instances the user will need to deactivate it via the central infotainment menu each time they start the car.

As a result, every new vehicle arriving from 7 July will have ISA equipped.
How to turn off ISA: Given Stellantis represents a large number of brands – also including Vauxhall, Peugeot, Fiat, Jeep and others such as Alfa Romeo and Maserati – the protocol for turning off the speed limiter tech might differ. Yet the spokesperson assures us that every vehicle will have the capability to deactivate ISA ‘using either the infotainment system or buttons on the dashboard depending on the model’.

How to turn off ISA: JLR told us that ISA can be ‘deactivated quickly and easily’ in all its new cars using a dedicated button on the steering wheel, which toggles through three levels of functionality. ‘By default, ISA in JLR models only indicates the speed limit and provides a warning if it is being exceeded.

Will UK cars have ISA from July 2024? All new Mazda models from 7 July will have ISA ‘unless the production cycle falls out of this timing’, suggesting some new cars that have been in showrooms for years might not be retrofitted for the UK market.
How to turn off ISA: In the Mazda2 (the sister car to the Toyota Yaris), ISA is turned off in the menu settings. In all other new Mazda models, there is a button on the right hand side of the dashboard called the ‘i-ACTIVSENSE mute switch’ which silences certain warning sounds from alerting the driver, including ISA. ‘A visual warning is still present as the system remains active and are only muted. There is no way to silence this ISA chime in isolation and due to the other safety features muted it is not something we would recommend,’ a Mazda spokesperson explained.
MERCEDES-BENZ

Will UK cars have ISA from 7 July 2024? A Mercedes-Benz UK spokesperson said ‘all models type approved since July 2022’ are already fitted with an ISA system.

We await the US brand’s response to understand if the functionality will be enabled for UK-bound new vehicles.
How to turn off ISA: The Tesla website says that ‘pressing the speed limit sign on the touchscreen mutes the speeding chime and display for the rest of the drive’.
