USA: Gasoline rationing goes into effect in the eastern United States. By the end of 1942, half of all US automobiles will be issued an "A" sticker which allows a mere 4 gallons of fuel per week.
By the end of 1942, half of US automobiles were issued an "A" sticker which allowed 4 gallons of fuel per week. That sticker was issued to owners whose use of their cars was nonessential. Hand the pump jockey your Mileage Ration Book coupons and cash, and she (yes, female service station attendants because the guys were over there) could sell you three or four gallons a week, no more. For nearly a year, A-stickered cars were not to be driven for pleasure at all.
The green "B" sticker was for driving deemed essential to the war effort; industrial war workers, for example, could purchase eight gallons a week.
Red "C" stickers indicated physicians, ministers, mail carriers and railroad workers.
"T" was for truckers, and the rare "X" sticker went to members of Congress and other VIPs. Truckers supplying the population with supplies had a T sticker for unlimited amounts of fuel.
Since a gas ration sticker was affixed to a vehicle's glass windshield, the reverse side was visible to the occupants. This offered the opportunity to give advice to the driver and passengers...
"Is this trip really necessary?"
"Share your car."
"To save tires, drive under 35."
The US produced ample supplies of domestic gasoline, but rubber was another matter. The vast majority of the world's supply of rubber was under Japanese control at this time and synthetic rubber production was still in its infancy. Gas rationing was primarily a measure to conserve rubber for tires.
This photo, taken during 1943, shows two government "Gas Snoopers" questioning the operator of the sedan as to why they were even driving. Note the deserted street and the "A" gas rationing sticker on the windshield.
