Weight special limitations or restrictions

The following weight tables establish the maximum legal gross weight of vehicles. Weight Table I requires the checking of all consecutive groups of axles to determine legal limits. It is referred to as the “inner bridge” system.

Table II is for primary and secondary highways only and requires measuring the distance in feet between the extremes of the first and last axle of any vehicle or combination of vehicles.

Vehicles with two (2) consecutive sets of tandem axles with a distance of less than 22 feet between the first and last axles of the consecutive sets shall comply with Gross Weight Table I.

Axle, wheel, and tire weight limits must be legal regardless of which weight table is used.

Vehicles operating on primary and secondary highways may operate in accordance with Table I or Table II at the discretion of the operator.

Bridge rules

Table II is for primary and secondary highways only and requires measuring the distance in feet between the extremes of the first and last axle of any vehicle or combination of vehicles.

Vehicles with two (2) consecutive sets of tandem axles with a distance of less than 22 feet between the first and last axles of the consecutive sets shall comply with Gross Weight Table I.

Axle, wheel, and tire weight limits must be legal regardless of which weight table is used.

Vehicles operating on primary and secondary highways may operate in accordance with Table I or Table II at the discretion of the operator.
