Replacing/Altering the first seat on a CMVSS certified bus will not be allowed, it will require other changes. CMVSS requires
a set number of UCRA positions, which mist be located in the first rows of each side. Moving a UCRA seat will also have an
impact on seat spacing so it is strongly recommended that any dealer moving a UCRA seat to accommodate this barrier,
request a new floor plan and adjust accordingly. If ordering a new bus with this feature, a new floor plan will be required
