A new UK survey suggests electric vehicle drivers may be more likely to find themselves creeping over the speed limit, with instant acceleration and quieter driving among the possible reasons.
Electric cars are smooth, quiet and responsive, qualities that make them enjoyable to drive. But could those same characteristics make it harder to keep an eye on your speed?
Research commissioned by Danish road safety technology company Ooono surveyed 1,000 UK motorists and found that 23% of drivers said they struggle to stay within lower speed limits when driving an electric vehicle (EV).
Among respondents who actually own an EV, that figure increased significantly, with 47% saying they find lower speed limits difficult to maintain.
Why can it be easier to speed in an electric car?
Electric vehicles deliver power differently from traditional petrol and diesel cars.
An electric motor can provide instant torque, meaning acceleration is available almost immediately when the driver presses the accelerator. Even EVs that aren't designed as performance cars can therefore feel particularly responsive at lower speeds.
At the same time, electric cars produce significantly less powertrain noise than combustion-engine vehicles.
Drivers of petrol or diesel cars may subconsciously use engine noise and revs as cues for how quickly they're travelling. With those cues reduced in an EV, motorists may need to rely more heavily on their speedometer and other driver-assistance systems.
That doesn't mean EVs inherently cause drivers to speed. Rather, the survey suggests their different driving characteristics can take some adjustment.
Nearly half of EV owners surveyed struggle with lower limits
According to the Ooono research:
-
47% of EV owners surveyed said they struggle to stay within lower speed limits when driving an EV.
-
23% of UK motorists overall reported the same difficulty.
-
35.6% incorrectly believed speed cameras have to be clearly signposted by law.
-
15.5% thought slowing down only when approaching a speed camera could prevent a speeding penalty.
-
12% believed there is an official speeding tolerance of 10% plus 2mph.
The results therefore point to a broader issue than EV acceleration alone: some motorists remain unclear about how UK speed limits and speed enforcement work.
Is there a 10% plus 2mph speeding rule in the UK?
No. The commonly quoted "10% plus 2mph" figure is not a legal entitlement to exceed the speed limit.
A posted speed limit is the maximum legal speed for that road. Drivers shouldn't assume they can legally travel above it simply because they have heard that police forces or speed cameras apply a particular tolerance.
The Ooono survey found that 12% of respondents believed an official 10% plus 2mph allowance existed.
Similarly, motorists shouldn't assume that every speed camera must be clearly signposted or that slowing down immediately before a camera makes speeding elsewhere acceptable.
The simplest rule is also the safest one: treat the number on the speed-limit sign as the maximum speed permitted.
How can EV drivers avoid accidentally speeding?
There are several ways drivers can make it easier to manage their speed when switching to an electric car.
Use your car's speed limiter. Many modern EVs allow drivers to set a maximum speed, which can be particularly useful in urban areas and lengthy 20mph or 30mph zones.
Pay attention to speed-limit displays. Modern vehicles increasingly use traffic-sign recognition and navigation data to display the detected speed limit on the dashboard or driver display.
Give yourself time to adjust to instant acceleration. If you're coming from a petrol or diesel vehicle, an EV's accelerator response may initially feel very different. Smoother accelerator inputs can help.
Don't rely on engine noise. EVs are much quieter than combustion cars, so regularly checking the speedometer is important rather than judging speed by sound alone.
Use driver-assistance technology appropriately. Depending on the vehicle, features such as adaptive cruise control, intelligent speed assistance and configurable speed warnings can help drivers remain aware of their speed.
Drivers should remember that assistance systems aren't a substitute for paying attention to road signs and conditions.
Do electric cars have speed warnings?
Many new electric cars ,as well as new petrol and hybrid vehicles, are equipped with technology designed to alert drivers to speed limits.
Intelligent Speed Assistance (ISA) can use information from cameras, road-sign recognition and navigation data to identify the applicable speed limit and warn the driver when the vehicle exceeds it.
The precise operation varies between vehicles, so drivers should familiarise themselves with the systems fitted to their particular car.
Importantly, these features don't remove the driver's responsibility to observe road signs and stay within the legal limit.
Instant acceleration is one of the biggest differences when switching to an EV
For many motorists, rapid and smooth acceleration is one of the first noticeable differences between an electric car and an equivalent petrol or diesel model.
Because an electric motor doesn't need to build revs in the same way as an internal-combustion engine, an EV can respond quickly and smoothly from a standstill.
That's useful for joining traffic, navigating junctions and everyday driving, but it can also mean drivers reach 20mph, 30mph or 40mph sooner than expected.
For anyone leasing their first electric car, it's worth taking some time to become familiar with the accelerator response, regenerative braking and driver-assistance settings before assuming the car will behave exactly like the vehicle they're replacing.
What does the survey tell us about EV drivers?
The research doesn't establish that electric cars make people speed. Instead, it indicates that some drivers perceive staying within lower speed limits to be more difficult when driving an EV, particularly existing EV owners.
There are also some limitations worth keeping in mind. The results are based on a survey of 1,000 UK motorists and reflect respondents' reported experiences and beliefs rather than measured speeding behaviour.
Nevertheless, the findings highlight how driving habits may need to adapt alongside vehicle technology.
As electric cars become increasingly common on UK roads, understanding features such as instant torque, regenerative braking, speed assistance and other driver aids will become an increasingly normal part of learning how to get the best from an EV.
Frequently asked questions
Are electric cars more likely to speed?
The survey does not prove that electric cars speed more often than petrol or diesel vehicles. However, 47% of EV owners surveyed said they find it difficult to stay within lower speed limits when driving an EV. Instant acceleration and quieter operation were identified as possible contributing factors.
Why do electric cars accelerate so quickly?
Electric motors can produce high levels of torque immediately, rather than waiting for an engine to build revs. This gives many EVs quick and smooth acceleration from low speeds.
Is 10% plus 2mph over the speed limit legal?
No. There is no general legal right allowing UK motorists to exceed the posted speed limit by 10% plus 2mph. Drivers should treat the posted limit as the maximum legal speed.
Can an electric car warn me if I'm speeding?
Many modern EVs have speed-limit recognition, configurable speed warnings or Intelligent Speed Assistance. Features differ between manufacturers and models, and drivers remain responsible for observing the applicable speed limit.
How can I stop accidentally speeding in an EV?
Regularly checking the speedometer, using a speed limiter where appropriate, paying attention to speed-limit recognition systems and becoming familiar with the EV's accelerator response can all help.
