Do you need a WSDOT permit for empty trucks or deadhead runs?
If you’re running a truck in Washington State without a load, commonly called a deadhead run, you might assume permits don’t apply. But that’s not always true. Understanding when a WSDOT permit is required can save you from fines, delays, and compliance issues.
What Is a Deadhead Run?
A deadhead run is when a truck travels empty after a delivery or before picking up a load. Even without cargo, you must follow WSDOT rules.
Do Empty Trucks Need a WSDOT Permit?
In most cases, empty trucks do NOT need a WSDOT permit, provided they meet standard legal limits.
You typically don’t need a permit if:
- Your truck stays within legal weight limits.
- Your vehicle dimensions (height, width, length) are compliant.
- There’s no specialized or oversized equipment attached.
However, permits are required if your empty truck is
- Exceeds legal size limits (e.g., wide trailers or specialized rigs)
- Still carries equipment that makes it oversized or overweight.
- It is configured in a way that violates standard regulations.
In WSDOT, your vehicle is regulated, not just your load.
Common Mistakes Truckers Make
Assuming empty trucks are exempt leads to violations. Common mistakes include driving an oversized trailer without a permit
- Forgetting that mounted equipment still counts toward dimensions.
- Assuming permits only apply to loaded trips
Even if empty, your truck must meet all legal requirements.
Why Compliance Matters
Failing to secure the correct permit even on a deadhead run can result in:
- Fines and penalties
- Delays at weigh stations
- Potential out-of-service orders
Stay compliant to protect your time, income, and reputation.
