CTEC Identification Numbers

Example

MC Maintenance Class: 5 numbers that identify a specific type of equipment

The first digit represents the major classification, (e.g., 03323):

Code	Major Classifications
Cars and Trucks
0	Single-axle drive
1	Four or six-wheel drive
Non-Truck Equipment (alphabetical)
2	(A - C) Boats thru Cutters
3	(D - K) Drill Rigs thru Grinders
4	(L - R) Loaders thru Rollers
5	(S - T) Sandblasters thru Tractors
6	(T - Z) Trailers thru Welders

The second and third digits represent the fuel used and the GVWR, (e.g., 03323):

Codes			GVWR
Alt Fuel	Gas	Diesel	Min.	Max.
	04	NA	4,000	4,999
07	06	NA	5,000	8,500
	08	09	8,600	10,000
	10	11	10,500	12,500
	12	13	14,000	16,500
	14	15	17,000	19,000
	18	19	19,000	23,000
24	22	23	23,000	26,000
28	26	25	26,001	30,000
	30	29	28,000	31,999
34		33	32,000	35,999
	38	37	36,000	39,999
44	42	43	40,000	45,999
	48	47	46,000	49,999
	52	53	50,000	60,999

The fourth digit represents the body type*, (e.g., 03323):

Code	Body Type
1	Dump Body - Tilt Cab
1	Light Trucks - Plow
2	Dump Body
2	Light Trucks - Extended Cab
3	Light Trucks - Utility Body
3	Dump Body - Rolloff
4	Utility Body - 6-Passenger
5	Cargo (Flatbed)
6	Cargo Body - 6-Passenger
7	Van
8	Cargo Body - Tilt Cab

On plow trucks, the fifth digit represents the plow and spreader combination*, (e.g., 03323):

Code	Number of Plows	Number of Spreaders
0	0	0
1	1	0
2	0	1
3	1	1
4	2	0
5	2	1
6	1	2
7	0	2
8	2	2
9	3	1

*Other body types and kinds of attachments are represented by fourth-and-fifth digit combinations outside the numbering system.
