Hello, as i recently just got my first boat, and i just got my boat license plate ect...

But im wondering where i am to put my license plate for the boat trailer!

Can anyone tell me where it needs to go? Thanks alot.

Back of trailer on the trailer frame.

Should be under the driver's (tow vehicle) side tail light.  Look to see if there is a clear lens underneath that provides light onto the plate at night.  Many taillights have a hanger built into them.  If not, bolt it to the frame where it is visible to the local constabulatory to save on all those late night traffic stops.
