As a petroleum supervisor, you must be able to ensure that vehicles and equipment are properly marked for
both safety reasons and to prevent commingling of products.
PART A - INSPECTION OF PETROLEUM MARKINGS
Tank vehicles include the M49A2C, M131A5C (Figure 1-1), M967, M969, M970, and M978. The driver's side
of the tanker is the roadside, and the passenger side of the tanker is the curbside.
Safety Markings. Vehicles used for the bulk transportation of gasoline, fuel oil, or other flammable
liquids will be marked on both sides and on the rear of the body with the word "FLAMMABLE" in 6-inch block
letters, and directly below where space permits, or on the same line with the words "NO SMOKING WITHIN
50 FEET" in 3-inch block letters and numerals. On vehicles which are used under tactical conditions,
markings will be lusterless white number 37875. Vehicles which are used on public highways in CONUS,
whether military or commercial design, must comply with Title 49, Code of Federal Regulations, Section
177.823, which requires the above markings in red lettering on a white background allowing a 1-inch margin
all around the lettering. Lettering will be gloss red number 11105 or 11136, and background will be gloss
white number 17875. On vehicles customarily used on public highways, the markings may be permanently
installed by painting or by use of adhesive-backed decals. Vehicles infrequently used on public highways and
camouflaged vehicles will be marked by the use of removable or reversible signs which are securely
fastened while in use. Individual vehicles and convoy must comply with the above requirements.
Type of Product Service. Fuel and oil dispensing vehicles and equipment used for servicing aircraft
will be marked with the grade of fuel or oil on each side of the tank. Marking will be lusterless white number
37875 in the following sizes:
Semitrailer........................6 inches high.
Trucks..............................4 inches high.
2-wheel trailers................3 inches high.
Tanker Vehicles Colors.
Yellow - warning color.
Red - fire protection materials and equipment.
Black or white - identification.
Gray or black - when using camouflaged.
U.S. Army and Registration Numbers.
Color - black or white.
Placement - sides and back.
Sizes - 2" on sides and 3" on back.
According to AR 750-58, there is no further requirement to mark vehicles and equipment with the
identification legend "U.S. Army." When vehicles and equipment are camouflaged, both the "U.S. Army" and
the registration number will be removed from vehicle/equipment exterior.
