If you plea guilty, then each will be a final conviction on your record.  This could cause your insurance rates to go up.... which could be expensive in the long run.  Many traffic ticket attorneys routinely handle tickets for a reasonable expense.  At least do a consultation with one or two to see the cost effectiveness in your area.  A good traffic ticket attorney may be able to get one or more of the citations dismissed as part of plea.... or work on a deferred sentence so that you can eventually get the tickets off your record completely.  The potential of a clear record is worth the investment in the ticket attorney.
