What it is
- A monthly or annual trucking permit
- Issued for trucks carrying divisible loads covered by a tarping system
- Used when the vehicle exceeds normal width limits due to load + tarp configuration
Typically applies when:
- Vehicle/load exceeds 8 ft 6 in width
- But does not exceed about 9 ft wide total
- Load must fully fit within the tarp system boundaries
Monthly & Annual Options
- $200 per month
- $2400 per year
Who uses this permit
Common industries:
- Construction (sand, gravel, asphalt)
- Agriculture (grain, hay, silage)
- Waste & debris hauling
- Recycling operations
Key requirements
- Load must stay within tarping system dimensions
- No bulging outside tarp limits
- Must comply with WSDOT route and safety rules
- Can be combined with other oversize permits if needed
Why it exists
Washington created this permit to allow:
- Frequent haulers to avoid buying repeated trip permits
- Safer containment of loose materials
- Legal operation of slightly overwidth covered loads
Simple explanation
If your truck is:
“Regularly hauling covered bulk material that makes the truck slightly wider than legal limits”
Then you use a monthly or annual tarping system permit instead of buying trip permits every time
