Yes, you likely will have problems in your home state of Pennsylvania if you fail to pay for your Wyoming speeding ticket.

Wyoming and Pennsylvania are both members of the Non-Resident Violator Compact (NRVC) which requires member states to suspend the driver’s license of those who get traffic tickets for moving violations in other states and fail to pay them. If you do not pay the WY speeding ticket, or comply with the Wyoming traffic courts in some other way to take care of the citation, then according to the NRVC your home state of Pennsylvania should suspend your license.

Section 1533 subsection (b) of the PA Vehicle Code in fact says that PennDOT shall suspend the operating privilege of any person who has failed to respond to a citation, summons or similar writ to appear before a court of competent jurisdiction of the United States or any state which has entered into an enforcement agreement with the department, as authorized under section 6146 (relating to enforcement agreements), for any violation of the motor vehicle laws of such state, other than parking, or who has failed to pay any fine or costs imposed by such court upon being duly notified in accordance with the laws of such jurisdiction in which the violation occurred.

Subsection (d) goes on to say that the suspension shall continue until such person shall respond to the citation, summons or writ, as the case may be, and pay all fines and penalties imposed or enter into an agreement to make installment payments for the fines and penalties imposed provided that the suspension may be reimposed by the department if the defendant fails to make regular installment payments and, if applicable, pay the fee prescribed in section 1960 (relating to reinstatement of operating privilege or vehicle registration).

So if you ignore your Wyoming speeding ticket than the WY courts should inform PennDOT at which time they are supposed to suspend your license until you do respond to Wyoming and take care of your speeding fine. You then may end up paying late fees to Wyoming as well as have to get your license reinstated in Pennsylvania meaning paying fees there as well. So not paying your Wyoming speeding ticket will in the long run likely cost you much more than the fine amount of the ticket if you pay on time.

Pennsylvania and Wyoming are also both part of the Drivers License Compact (DLC). This Compact requires the Wyoming courts to inform PennDOT of your speeding offense if you are convicted of it. So if you do pay the ticket PA will still be notified of the speeding offense, however the good news is that you will not get points for it on your PA driving record.

Although reported to PennDOT, minor traffic offenses such as speeding, red light, stop sign, etc., will not appear on your driving record, unless you are a CDL holder. Also points are not assessed to your PA driving record when convicted of a point related offense in a DLC member state.

So if you pay the ticket, and thus are convicted of offense, the PA Driver and Vehicle Services will be informed but not place the violation on your record or assigned points. Having the conviction in Wyoming but not counting against you in PA is much better than ignoring the ticket and getting your license suspended (which would be noted on your driving record).

If you instead pay your Wyoming speeding ticket the WY offense should not be placed on your PA driving record and thus it is doubtful, but not impossible, that your insurance company will find out about the violation and raise rates due to it. If you fail to appear or fail to pay the WY speeding ticket though a suspension would occur and then your insurance company could raise your rates and if you do not get your license back in a short period of time possibly cancel your policy.
