Test drives on frozen peatland have been carried out. The main purpose of the tests was to make a comparison with previously made tests on unfrozen peatland. Another was to develop competence to carry out field tests under winter conditions. The development in frost- and snow- depth were measured during a period of three months before the tests. Density and hardness of the snow were measured at the same time the tests took place. The vehicles were driven in test-tracks one for each vehicle. Maximum number of passages were 30. The time needed to complete each passage was registered for later calculation of vehicle speed.
