tho that page has DPS across the top, notice the MSB logo - it appears that's a third-party company to help DPS collect surcharges.
what are surcharges? check out the dps page on them.

i noticed that their opt in page asked for personal info!!!

so, even tho the DRP page mentions MSB, if it were me, i'd check w/ DPS [call them] to make sure that a) the amnesty pgm is legit and b) that MSB is legit. you never know who's out there wanting your info.
