Roof height definition
Roof height means distance in vertical Z from cabin reference point to highest point of roof w/o sunroof
Roof height means the vertical distance between the highest point of the roof or parapet of one building, and the average finished grade of the front lot line or the average finished grade of the front yard eight feet (8') from the structure, whichever distance is less.
Roof height means the maximum height of a vehicle (rounded to the nearest inch), excluding narrow acces- sories such as exhaust pipes and anten- nas, but including any wide accessories such as roof fairings. Measure roof height of the vehicle configured to have its maximum height that will occur during actual use, with properly inflated tires and no driver, passengers, or cargo onboard. Determine the base roof height on fully inflated tires hav- ing a static loaded radius equal to the arithmetic mean of the largest and smallest static loaded radius of tires a manufacturer offers or a standard tire EPA approves. If a vehicle is equipped with an adjustable roof fairing, meas- ure the roof height with the fairing in its lowest setting. Once the maximum height is determined, roof heights are divided into the following categories:
(1) Low-roof means a vehicle with a roof height of 120 inches or less.
(2) Mid-roof means a vehicle with a roof height between 121 and 147 inches.
(3) High-roof means a vehicle with a roof height of 148 inches or more.
(1) Spark-ignition engines, light heavy-duty compression-ignition en- ▇▇▇▇▇, light heavy-duty vocational ve- hicles and heavy-duty pickup trucks and vans.
(2) Medium heavy-duty compression- ignition engines and medium heavy- duty vocational vehicles and tractors.
(3) Heavy heavy-duty compression-ig- nition engines and heavy heavy-duty vocational vehicles and tractors.
