Two thirds of businesses are saving money on their fuel bills thanks to telematics, according to a survey.
A poll of 500 UK businesses with vehicles found 38% used the vehicle black box device for a variety of reasons beyond "simply tracking" them.
The study, commissioned by RAC, said of those, 68% reported a drop in fuel costs, while 55% saw a reduction in wear and tear, and 48% experienced a cut in downtime for their vehicles, contributing to further savings.
As well as costs, 43% of firms said using telematics supported their Duty of Care policies, while more than half (58%) saw a reduction in speeding incidents and fines, and further 52% said there were fewer accidents involving staff.
In addition, one in 10 (11%) said insurance premiums decreased due to the adoption of the device.
RAC telematics managing director Nick Walker said: "The idea that businesses are using telematics just to track their staff is really quite outdated now, they are much more interested in information about how the vehicle is performing and getting alerts about parts that need replacing, or vehicles that need servicing.
"Telematics is a key aspect of Duty of Care policies now, helping to promote safer driving so there are fewer speeding fines or accidents, which all contributes to less downtime and therefore a much more efficient business."
Across the country, around 45% of businesses in London have telematics, above the national average of 38%. This is followed by Scotland and the North East, with both regions reporting 44% of the use of the device. The lowest take-up was in Northern Ireland (27%), followed by Wales (30%) and the North West (30%).
Businesses in the manufacturing sector are among the highest users with half (49%) of those surveyed saying they have telematics, followed by the transport and distribution sector with 45% of take-up. Sectors with the lowest take-up include communication services at 31%, then retail at 36% and construction at 38%.
