Will PennDOT renew my driver's license if my passport is about to?
If your drivers license is about to expire, renew it if you plan to continue driving. If your passport is about to expire, renew that too sooner or later, youll need to show a valid passport to some authority figure. I doubt the folks at PennDOT will check your passport expiration date when renewing your drivers license, but you never know. Renewing the passport first might save you some trouble.
