Does in-car Black Box telematics really work?

Is telematics tech a solution for safer driving? We speak to some young drivers with first-hand experience of black boxes

Black boxes offer young drivers a practical way to cut insurance premiums, while keeping track of how well they're driving. However, critics argue that they're another step towards "big brother" society. Sure to further that fear is the suggestion the tech will be automatically fitted to cars by 2025, and the only way in which drivers won't be monitored will be if they 'opt out' of the technology. 

Currently, there are around 300,000 live car insurance policies in the UK where the driver is hooked up to telematic technology. While this is only a small proportion of the total market, the growth and popularity of of black boxes shows little sign of slowing. 

• Cheapest cars to insure

Back in 2011, we looked into what was then brand new technology. Three years down the line, we want to see how the public now perceives it. We spoke to three drivers who have taken the plunge to see how they've found it, and what they think about black boxes becoming standard fit in the future. 

Black Box telematics: Young driver benefits

First-time driver Ashley Gilbert didn’t have much choice when it came to fitting a black box, after struggling to find suitable cover. Ashley, 17, from Barlborough, near Chesterfield, Derbyshire, bought a Vauxhall Corsa and found only a handful of providers would take on an under-18. He decided to go with Carrot car insurance and fit its i-box. With it he could pay his premiums on a monthly basis and also win rewards such as cashback at high street shops, based on good driving.

Four months in and Ashley told Auto Express he doesn’t even think about it any more. “I was wary about how to drive at first and checked the score on my app every day,” he said. “I think the i-box has taught me to drive better, so I don’t worry about it any more.” Ashley also explained the box ensures he doesn’t speed, which means it’s safer for him and others on the road, too. 

But would he rather drive without one? “To be honest, no, I’m not bothered either way. It means you can track your car, too, which is brilliant,” he said. Ashley also believes that if everyone had a black box fitted, the roads would be safer because crashes and thefts would be reduced.

However, as a young driver who is so reliant on the discounts and reductions that the tech offers, he hopes any potential “opt out” wouldn’t have a negative impact on insurance costs. He added: “Thieves may learn how to take the boxes out of cars so they can’t be tracked, and it may not be cheaper for younger drivers.”

Black Box telematics: Helping drivers learn

Klaudia Kmiecak chose to install a black box due to the lower premium it offered. As a 23-year-old driver, insurance prices were still too high without fitting some sort of telematics. Klaudia, from Leicester, also chose Carrot car insurance, mainly because of the benefits and rewards offered as part of her policy.

Klaudia told Auto Express: “My premium is much cheaper now. Previously, I was insured with another company as a second driver on my boyfriend’s insurance, so I didn’t have a no-claims bonus or protection for the three years I had been driving.”

Her Renault Clio was fitted with a black box in January this year and since then Klaudia feels like her driving has improved. She said: “The first few months I was very conscious of it and wanted to make sure I was driving right. Now my driving has improved so I’m not so aware of it.”

Klaudia also thinks it should be compulsory for young drivers like herself.  “All new drivers should definitely have one for at least three years,” she told us. “You carry on learning way past your test – passing the test is an easy thing to do.”

Black Box telematics: When the tech goes wrong

Despite the undoubted positives that telematics provide, like all technology, some people do experience problems. One of those is Rebecca Timms, 29, from Bournemouth, who had a black box fitted to her Citroen C4 Picasso through She signed up to a contract, which allowed her to do a set number of miles per year, with good driving rewarded with bonus mileage each month.

She’d been averaging more than 90 out of 100 each month, but suddenly she dropped to 60 and was told by the data that she had been speeding. Rebecca also found that one journey hadn’t been logged. Suspecting issues with her box, she contacted

The company told her that the box was working correctly, but if the signal dropped out it was designed to cancel the whole journey to avoid giving incomplete and wrong scores. Rebecca said: “I couldn’t get any feedback at all. I want to improve my driving, but I can’t address it if they can’t tell me how I’ve performed.” 

Autonomous cars could be on the road by 2015

Auto Express got in touch with, which told us it had contacted Rebecca and agreed to return her mileage to her normal high average as a gesture of goodwill and provide her with free advice on how to increase it further.

A spokesman said: “Recently, she performed disappointingly compared to her own high standards and queried our data. After a rigorous examination, we are satisfied that her score was fair.”

Despite her problems, Rebecca is still supportive of telematics tech. She said: “I think it is a good idea for people to have it, as long as it is governed properly and managed correctly. Any errors need to be corrected as soon as they occur.”

Exactly how do black boxes work? 

The Association of British Insurers' official line on telematics tech:

• Black boxes measure driving in different ways, but most consider mileage, type of road, speed and braking problems

• Premiums may be adjusted at set points in the policy, based on driving behaviour. With other policies, premiums will stay the same, although you'll be rewarded with non-monetary benefits

• Behaviour-based policies aren't always cheaper, especially if you frequently drive late at night, on unsafe roads or drive poorly

• Named drivers or others entitled to drive the car will also be used by the insurer to calculate overall performance 

• There is sometimes a cost associated with having the device fitted or removed. If you cancel the policy early, the insurer couls also levy a charge to recover the cost of the device
