To keep Pennsylvania roads safe, all trailers on public roads must be registered with the Pennsylvania Department of Transportation (PennDOT). The process may depend on how you purchased your trailer.

Steps to Register Your Trailer

Here’s how to register your trailer in Pennsylvania:

1. Gather your documents: You’ll need a certificate of title or manufacturer’s statement of origin, a personal ID, and the bill of sale.
2. Contact PennDOT: You can register your trailer through an authorized agent or PennDOT. You’ll need to fill out forms, submit required documents and pay a fee.
3. Find out if you need an inspection or titling: You may need an inspection if you’re buying a trailer with a loaded vehicle weight (GVWR) over 3,000 pounds or a trailer with brakes. Trailers with a GVWR over 3,000 pounds must also be titled with PennDOT — so do trailers purchased out of state and homemade trailers.
4. Consider additional registration needs: If you’re using a trailer as a food truck, for example, you may need a Mobile Food Facility Permit and a Public Health Permit, and may need to meet additional requirements.
5. Complete your registration: Once you complete your registration, you’ll receive a registration card and plates. Place the plates on the trailer and keep the card with your trailer at all times.
6. Keep your registration current: You need to re-register online or with PennDOT before your registration period is up. If you move, report your new address within 15 days of moving.

Why It’s Safer to Buy Through a Trusted Retailer

Buying a trailer through an online ad or from a friend comes with some risks — in a worst-case scenario, you may end up with an unregistered trailer.

If the seller can’t produce the title, ask them to request a duplicate title from PennDOT. If they’re unwilling, there could be a problem with the title, or the trailer may even be stolen.

If you’ve purchased a pre-manufactured trailer, ask the seller to contact the manufacturer for a duplicate certificate of origin. For homemade trailers, PennDOT will usually require receipts and an inspection.
