MCD-1751 Form – If you operate commercial trucks in Texas and need to haul divisible loads slightly over legal axle or gross weight limits, the MCD-1751 Form is your key to compliance. This official application grants an Annual Over Axle/Over Gross Weight Tolerance Permit from the Texas Department of Motor Vehicles (TxDMV). It lets qualified motor carriers exceed standard weight limits without violating state law.
In this complete guide, we break down everything: what the permit allows, who qualifies, exact fees, step-by-step application instructions, restrictions, and a direct MCD-1751 PDF download. All information comes directly from the official TxDMV website and form (revised 06/23, still current as of 2026).
What Is the MCD-1751 Form and the Weight Tolerance Permit?
The MCD-1751 is officially titled the “Over Axle and Over Gross Weight Tolerance Permit Application.” It is the required form to apply for (or renew) an annual permit that authorizes vehicles to operate with:
- 10% tolerance over the legal axle weight, and
- 5% tolerance over the legal gross weight.
These tolerances are calculated based on the vehicle’s outer bridge distance, not its registered weight. The permit applies only to divisible commodities (loads that can be broken down) and does not allow exceeding legal size limits or manufacturer tire load ratings.
Important note for ready-mixed concrete trucks: Gross weight may not exceed 69,000 pounds under this permit.
The permit is issued per vehicle (power unit) and is valid for one year from the start date you select.
Who Needs a Texas Weight Tolerance Permit? (Eligibility)
You qualify if you:
- Hold a valid USDOT Number (TxDMV verifies it against FMCSA records).
- Operate vehicles registered in Texas for their maximum gross weight.
- Haul divisible loads on Texas state-maintained or county roads.
First-time applicants hauling non-agricultural products must file a $15,000 Over Axle/Over Gross Weight Tolerance Permit Bond (Form 1753) or an Irrevocable Standby Letter of Credit with TxDMV before approval. Agricultural product haulers (timber, cotton, livestock, etc.) are exempt from the bond requirement. If you haul both ag and non-ag products, select “Non-Agricultural.”
Where Can You Operate? (Road Restrictions)
- Allowed on state highways and county roads in the specific counties you select.
- NOT allowed on the Interstate Highway System (including frontage roads).
- Prohibited on any load-posted bridge if your weight exceeds the posted limit — unless it is the only public access to your origin or destination.
- Special grandfathering applies to certain segments of US 59, 77, 281, 84, and SH 44 if later designated as I-69.
Current 2026 Fee Structure (Per Vehicle)
Fees consist of a $90 base fee + $5 TxDMV administration fee plus a county designation fee based on how many counties you select. Total fees per vehicle are:
| Number of Counties | County Fee | Total Fee (incl. base + admin) |

Frequently Asked Questions (FAQs)
Is the MCD-1751 permit the same as a regular overweight permit?
No — regular permits are for non-divisible loads or higher weights. The Weight Tolerance Permit is specifically for small overages on divisible loads.
How long does it take to get approved?
Online via TxPROS: 1–4 business days. Mailed applications may take longer.
Can I change counties later?
No. Select all counties you might need at application time.
Do I need this permit for agricultural products only?
No — it works for both, but non-ag requires the bond.
