"On average, you could save £244 with a black box compared to standard van insurance policies.2
Aside from the cost savings you can get from a black box policy, there are other benefits to this kind of insurance. If you get into an accident that wasn't your fault, your insurer should be able to use details like your speed data to help support any claims you make. It can also help if you need to disprove any false claims made against you by another driver."
