Texas Axle Regulations

Maximum Legal Weight Allowed

Texas has established size and weight limits for vehicles and loads moving with or without oversize and/or overweight permit on Texas roadways and bridges. Weight includes the weight of the vehicle or combination, plus the weight of the load being transported.

Axle Group                  Maximum

Single                           20,000 pounds

Tandem                        34,000 pounds

Triple                           42,000 pounds

Quadrum                     50,000 pounds

Gross Vehicle Weight  80,000 pounds

Note: An axle group must have a minimum spacing of 40 inches between axles within the group. The Federal Bridge Formula is to be used to determine the maximum legal weight on any group of two or more consecutive axles.

Maximum Permit Weight Allowed

The maximum permit weight for an axle or axle group is based on 650 pounds per inch of tire width or the following axle or axle group weight, whichever is the lesser limit.

Axle Group                                                    Maximum

All tires must appear to be properly inflated - even though a gauge check is not required.

Tires should be inspected visually, and the tread should be measured with a tread depth gauge calibrated in 32nds of an inch if it does not have tread wear indicators.

A tire used on a moving vehicle may not have on its periphery a block, stud, flange, cleat, or spike or other protuberance of a material other than rubber that projects beyond the tread of the traction surface, unless the protuberance:

(1) Does not injure the highway

(2) Is a tire chain of reasonable proportion that is used as required for safety because of a condition that might cause the vehicle to skid.

Texas Road Conditions

TxDOT and the government of Texas urge people driving through work zones and areas that are under any type of construction to slow down.

Respect traffic signs and stay alert while driving through these zones.

TxDOT advises to stay calm and be patient when driving through work zones, reduce speed and pay attention to signals, flaggers, and other drivers.

There is a Work Zone awareness campaign in effect where TxDOT reminds the drivers about Move Over/Slow Down law that requires drivers to move over or slow down when approaching TxDOT crews, law enforcement, emergency vehicles or tow trucks stopped on the roadside or shoulder with flashing blue or amber lights.

Failure to do so can result in fines up to $2,000.


Texas Manufactured Houses and Mobile homes

Single Trip Permit 

TxDMV issues a single-trip permit for the movement of manufactured housing or buildings exceeding Texas legal size limits when transported on any returnable undercarriage or temporary chassis system.

Single-trip manufactured housing permits may only be used for one movement, during the times specified on the permit (not to exceed five days.

You may not transport manufactured housing on the following holidays: New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

Manufactured housing exceeding legal gross, axle or axle group weights must obtain a General Single-Trip Permit.

In the case of a double-wide manufactured house, moving on its own set of axles, each half requires a permit. To move the double-wide manufactured house as one unit on a set of house moving dollies requires a permit for a house move.

Annual Permit 

A manufactured housing annual permit is for the transportation of a manufactured house from a manufacturing facility to a temporary storage location, not to exceed 20 miles from the point of manufacture. 

Fee: $1,500
