Vehicles were used for military maneuvers and demonstrations when not in use in the field. This group of touring cars and military trucks were used by Canadian soldiers in maneuvers at Camp Hughes, Manitoba.

Gasoline was a controlled good during the Second World War, The selling and buying of gasoline was done through the use of ration coupon books like the ones here, and were intended to prevent its hoarding or wasting given the limited availability of gasoline during wartime.
Gasoline coupons were linked to a single vehicle, the plate of which was recorded at the front of the license. However, only the owner of the vehicle was allowed to make use of the ration coupons to buy gasoline, which had to be intended for that car only, and not for any other purposes or activities.
