This unusual vehicle is a lifeboat launching tractor used by SARA. Notice the blue light bar fitted to the rear. Such a vehicle can only be used on private land with the blue light bar fitted. To be used on the roads, it requires an official dispensation to do so by the Secretary of State. Only the RNLI have a blanket exemption for lifeboat launching vehicles with blue flashing lights.
