The rise of GPS jammers has been widely predicted for a number of years, but little evidence currently exists on their use. Jammers could prevent the rise of pay-as-you-go car insurance or road users charging. Although communications regulator Ofcom has closed down some websites selling jammers, most are not based within their jurisdiction

Small short-range jammers have created isolated problems in the US. In late 2009, a single truck using a GPS jammer caused headaches for technicians at Newark Liberty International Airport as it interfered with a navigation aid every time the truck passed on the New Jersey Turnpike. Truck drivers and other drivers who want to conceal their movements from tracking devices sometimes use basic GPS jammers embedded in their vehicles. Trucking companies use GPS systems to monitor the location of their trucks and cargo, and to keep tabs on their drivers' compliance with company rules and federal regulations. Auto rental companies use GPS in the US to track whether customers violate the terms of a rental contract by speeding or leaving a geographic area. GPS is also being used by auto insurance companies for "pay as you go" policies that offer reduced rates for drivers, metering their bill based on how far and when they drive, as well as other factors.

Future versions of the technology will also be able to “spoof” the GPS system, raising the prospect of thieves stealing, for instance, a lorry with a tracker but giving the impression that it is still proceeding to its intended destination.
