Pennsylvania Size, Weight, and Equipment Rules
Pennsylvania Size, Weight, and Equipment Rules
Pennsylvania enforces state size and weight limits in addition to federal CDL requirements. The exam tests the common limits and the equipment that must be on a doubles/triples combination.
Common Pennsylvania limits
- Width: 8 feet 6 inches (102 inches), excluding mirrors and certain safety devices.
- Height: 13 feet 6 inches.
- Trailer length: 53 feet for a semitrailer on qualifying routes; twin trailers are typically limited to 28.5 feet each.
- Gross weight: 80,000 pounds; single axle 20,000; tandem 34,000; bridge formula applies.
- Overweight or oversize movements require a permit.
Equipment
- Mud flaps, working lights, reflectors, and reflective tape.
- Fire extinguisher, warning triangles, and spare fuses.
- Safety chains on the dolly and proper gladhands.
- Brakes on all axles as required; ABS if equipped.
Worked example
A driver plans a 53-foot trailer with a 28.5-foot pup on a Pennsylvania route. The combination is within the twin-trailer length limit, but the driver must confirm the route is designated for doubles and that the gross weight with the load is under 80,000 pounds and each axle is legal. If the load pushes the drive tandem to 35,000 pounds, the driver needs a permit or a load adjustment.
Traps
- Assuming federal limits override Pennsylvania's route restrictions.
- Forgetting that mirrors may extend beyond 102 inches but cargo may not.
- Mixing up trailer length and overall combination length.
- Ignoring permit requirements for oversize loads.
