Just saw it pull someone by mine

Its a black volvo S60.

has a blind spot mirror attachment on the passenger side mirror.

P053EJA is NOT on the Motor Insurance Database today

are police cars registered on a different kind of database or somethin - or are they driving uninsured? hehehe jk

haha what a way to check lol

they are insured for the purposes of the Road traffic act...but not in the same way that you insure your car.
Long story short its a bit like bus companies...you have to have a huge "contingency fund"....and some sort of insurance for liabilities...but they arent registered on the MID...clear as mud?
