Reporting Measurements
Whenever vertical clearance measurements are taken, both the
actual and the signed clearance should be reported to the district
oversize/overweight permit coordinator and to the district bridge inspection
personnel.
The Motor Carrier Division of the TxDMV bases the clearance
shown on the district permit maps on correspondence from each district.
The vertical clearances on the district permit maps should show
clearances in one-half foot increments, but never greater than the
signed clearance.
