Damage Assessment Fee Calculator
The table below shows the cost per mile fee assessed for various over-legal weight axle groups. It is used to calculate the overall state fee for over-legal weight Single Trip and Job Permits. Axle group cost factors in per mile traveled.
| Total axle group weight (in pounds) | Two axles spaced within 8 feet or less | Three axles spaced within 9 feet or less | Four axles spaced within 14 feet or less |
|---|---|---|---|
| 0 - 34,000 | $0.00 | $0.00 | $0.00 |
| 34,001 - 36,000 | $0.12 | $0.00 | $0.00 |
| 36,001 - 38,000 | $0.14 | $0.00 | $0.00 |
| 38,001 - 40,000 | $0.18 | $0.00 | $0.00 |
| 40,001 - 42,000 | $0.21 | $0.00 | $0.00 |
| 42,001 - 44,000 | $0.26 | $0.05 | $0.00 |
| 44,001 - 46,000 | $0.30 | $0.06 | $0.00 |
| 46,001 - 48,000 | N/A | $0.07 | $0.00 |
| 48,001 - 50,000 | N/A | $0.09 | $0.00 |
| 50,001 - 52,000 | N/A | $0.10 | $0.04 |

| 62,001 - 64,000 | N/A | N/A | $0.11 |
| 64,001 - 66,000 | N/A | N/A | $0.12 |
| 66,001 - 68,000 | N/A | N/A | $0.15 |
| 68,001 - 70,000 | N/A | N/A | $0.16 |

A damage assessment fee is calculated by adding the rate for each axle group and then multiplying the sum by the miles traveled. For example, with a single axle steer group at 13,000, a tandem drive group at 38,000, and a tridem lowbed at 60,000, the damage rate would be $ 0.33 ($0 + $0.14 + $0.19) per mile traveled.
For an overweight single trip permit, add the damage assessment fee to the base $15.00 permit fee.
For an overweight job permit, add the damage assessment fee to the base $36.00 permit fee.
To reduce damage assessment cost-per-mile fees, add additional axle(s) to vehicle combination, reduce the net weight of the load, or shift the load to transfer weight to other axles.
