I have noticed that as I drive around town in my 1994 Ram PU the speed minder signs show that my speedometer display is about 10mph slower than my actual speed. Is there a fix for this?

maybe speed cable loose or worn out. take off wheel side and look at it. if that side OK check dash side more difficult). or could be speed gauge in dash .

have you switched tires recently?

You must have tires larger than the stock size the truck came with. I don't know if '94 has a replaceable gear on the end of the speedo cable where it goes into the trans or maybe the transfer case if a 4x4.
