Every state has a slightly different procedure... however, if you ignore a ticket, then the court can issue a warrant for your arrest.  However, if you are arrested in a different state, then most states will not extradite for a traffic ticket.  This means that the state won't involuntarily drag you back. If the traffic ticket is the type that could result in suspension, then the ticketing state could ask your home state to enforce the suspension under the full faith and credit theory. So... bottom line, nothing may happen, but the potential consequences could be very inconvenient should they actually occur.
