Federal Rules, Pennsylvania Rules
If your trucks cross state lines, the Federal Motor Carrier Safety Regulations apply to any commercial motor vehicle of 10,001 pounds or more. Pennsylvania also applies those federal rules to carriers that operate only inside the state.
Under 67 Pa. Code Chapter 231, PennDOT adopts the federal safety regulations — including driver qualification (Part 391), drug and alcohol testing (Part 382), hours of service (Part 395), and inspection and maintenance (Part 396) — for intrastate operations, with some Pennsylvania-specific modifications.
The biggest difference is where the line is drawn. For trucks that stay in Pennsylvania, the rules start at 17,001 pounds instead of the federal 10,001 pounds. That gap is where many small carriers get confused.

What Pennsylvania Carriers Need to Know
The 17,001-pound intrastate threshold
Pennsylvania's intrastate rules apply to vehicles with a gross vehicle weight rating, gross combination weight rating, or actual weight of 17,001 pounds or more (whichever is greater), or to any vehicle carrying hazardous materials that must be placarded.
Be careful with the word “intrastate.” A trip that never leaves Pennsylvania can still be interstate commerce if the freight started or will finish its journey in another state — for example, a container picked up at a port and delivered to a warehouse in-state. In that case the federal 10,001-pound threshold applies.
CDL drivers: drug testing and the Clearinghouse apply either way
The DOT drug and alcohol rules in Part 382 follow the CDL, not the route. Any driver who needs a CDL — interstate or intrastate — must be in a random testing program, pass a pre-employment drug test before driving, and be queried in the FMCSA Drug and Alcohol Clearinghouse before hire and at least once a year.
Grandfathered intrastate medical qualification
Pennsylvania has a narrow exception for long-time intrastate drivers. A driver who was regularly employed as of September 23, 1995 and cannot meet the federal physical qualification standards may still be qualified for intrastate driving if certified by a medical examiner and the motor carrier — but only until the existing condition significantly worsens or a new disqualifying condition develops.
It does not apply to interstate driving. Confirm eligibility with PennDOT before relying on it.
Fuel tax: MCRT vs. IFTA
Pennsylvania requires a road tax decal for “qualified motor vehicles” — a two-axle power unit over 26,000 pounds, any power unit with three or more axles, or a combination over 26,000 pounds.
- MCRT (Motor Carriers Road Tax): for carriers that operate only in Pennsylvania. You still track miles and fuel by vehicle.
- IFTA: for carriers that operate in Pennsylvania and other states and use Pennsylvania as their base jurisdiction.
Fuel tax filing is handled by the PA Department of Revenue, not by us — but a missing decal is an easy roadside finding, so it belongs on your compliance checklist.
For-hire passenger carriers and household goods movers
Carriers moving passengers or household goods for hire between points in Pennsylvania also need authority from the Pennsylvania Public Utility Commission (PUC), in addition to meeting the safety rules above.
Running in Both Pennsylvania and New Jersey?
The two states draw the line in different places for trucks that stay in-state. Once a truck crosses the river, federal rules apply either way.
| Pennsylvania | New Jersey | |
|---|---|---|
| State rule | 67 Pa. Code Chapter 231 | N.J.A.C. 13:60 |
| In-state (intrastate) trucks covered from | 17,001 lbs, or any placarded hazmat load | 10,001 lbs |
| Interstate trucks covered from | 10,001 lbs (federal) | 10,001 lbs (federal) |
| CDL drug & alcohol testing + Clearinghouse | Required | Required |
Example: a 14,000-lb box truck that only runs inside Pennsylvania generally falls below the state's intrastate threshold. The same truck making deliveries inside New Jersey — or crossing between the two — is covered.

Pennsylvania DOT Compliance FAQ
Do Pennsylvania intrastate carriers have to follow FMCSA regulations?
Yes, for most commercial trucks. Under 67 Pa. Code Chapter 231, Pennsylvania adopts the federal safety regulations — including driver qualification, drug and alcohol testing, hours of service, and inspection and maintenance — for intrastate vehicles of 17,001 pounds or more, and for any vehicle carrying placarded hazardous materials.
Does a 12,000-lb truck that only runs in Pennsylvania need a driver qualification file?
Generally not under the state intrastate rules, because it is below the 17,001-pound threshold and is not carrying placarded hazmat. But if that truck crosses into another state, or hauls freight that is part of an interstate shipment, the federal 10,001-pound threshold applies and the driver needs a full DQ file.
Do Pennsylvania intrastate CDL drivers need random drug testing and Clearinghouse queries?
Yes. The DOT drug and alcohol testing rules apply to every driver who needs a CDL, whether the driving is interstate or intrastate. That includes pre-employment testing, random testing, and Clearinghouse queries before hire and at least once a year.
Is Pennsylvania MCRT the same as IFTA?
No. MCRT (Motor Carriers Road Tax) decals are for qualified vehicles that operate only in Pennsylvania. IFTA decals are for carriers that operate in Pennsylvania and other jurisdictions and use Pennsylvania as their base state. Both are administered by the PA Department of Revenue.
Do you work with carriers outside the Philadelphia area?
Yes. We serve carriers across Pennsylvania. Driver files and Clearinghouse queries are managed remotely, and drug tests and physicals are coordinated through a nationwide network of collection sites, so your drivers can test close to where they work.
