To adopt a highway means your group signs a formal volunteer agreement with your state’s department of transportation to pick up litter along a specific stretch of road, usually about two miles, several times a year. In return, the state posts a sign at both ends of your section with your group’s name on it. The program is free to join, every state runs some version of it, and the arrangement is a recurring volunteer commitment rather than any kind of lease or ownership of the road.
What You Actually Agree To
The deal is narrow and specific. Your group handles surface-level litter removal within the right-of-way, the grassy or unpaved strip between the travel lanes and the property line. The state handles everything else: road repairs, mowing, drainage, snow removal, and anything involving traffic. You get no authority over the road and no interest in it.
The state provides the gear you need to do the job safely. That means high-visibility vests and heavy-duty trash bags, delivered or picked up from a state facility depending on the program. After each cleanup, you leave the filled bags at a designated spot along the shoulder and a state crew comes by later to haul them away. The state also fabricates, installs, and maintains the recognition sign.
Adopt-a-Highway vs. Sponsor-a-Highway
Some states run a second program that looks similar but is not the same thing. In a sponsor-a-highway arrangement, a business pays a monthly fee and professional crews do the actual cleanup. The sponsor’s name goes on the sign, but no one from the sponsoring company picks up trash. These paid arrangements are more common on high-traffic freeways where volunteer work would be unsafe. If you are a business looking at a sign as advertising, that is the sponsor program; the volunteer adopt-a-highway program is free and requires your group to show up and work.
Who Can Sign Up
Eligibility is broad. Nonprofits, civic groups, businesses, churches, scout troops, school clubs, families, and individuals can all apply. Most states set a minimum age for participants somewhere in the range of 10 to 16, with higher minimums on busier roads. Minors need adult supervision, typically at a ratio of one adult for every five to eight young volunteers.
States do screen applicants and can reject or ask you to modify names tied to discrimination or illegal activity, though that authority has constitutional limits where viewpoint alone is the reason.
How the Signup Works
Applications go through your state DOT, usually via an online portal. You name a group coordinator, who becomes the single point of contact with the agency and is responsible for scheduling cleanups, distributing safety gear, and filing reports.
During the application you pick an available segment from the state’s inventory. Most segments run about two miles. You also submit your group’s name exactly as you want it on the sign. Approval and sign installation generally take a few weeks, depending on the state’s backlog.
What a Cleanup Day Looks Like
Your coordinator notifies the local maintenance office about a week in advance of each cleanup. That heads-up avoids conflicts with scheduled road work and sets up the bag pickup afterward. Volunteers collect their vests and bags beforehand.
On the day itself, everyone wears the vests and stays on the unpaved shoulder and right-of-way. No one steps into the travel lanes or crosses the highway. States also recommend heavy work gloves, closed-toe boots or sturdy shoes, long pants, and long sleeves. Headphones and anything else that distracts drivers or impairs your hearing are prohibited.
Certain things are off-limits to touch. If you come across hazardous waste, medical waste, or anything that looks dangerous, leave it alone and report it to the department. After the cleanup, the coordinator files a short activity report with the number of bags filled and hours worked.
Safety and Liability
Working next to moving traffic carries real risk. Every participant signs a liability waiver or volunteer registration form before working, releasing the state from responsibility for injuries during the cleanup. No one participates without signing.
The federal Volunteer Protection Act adds a layer running the other way. A volunteer working for a governmental entity is generally not liable for harm they accidentally cause within the scope of their volunteer duties. That protection does not apply to gross negligence, willful misconduct, or operating a motor vehicle at the time.
The practical rules carry more weight day to day than the paperwork does. Never work in the dark, never work alone, never wear headphones, and never step into a travel lane to chase trash. On roads where speeds are too high or shoulders too narrow for safe volunteer work, the state may only offer the paid sponsor model instead.
How Long You’re Committed
Most states ask for a two-year initial term, though some set it shorter or longer. Within that term, you typically owe a minimum number of cleanups per year, often four spaced across the seasons. Busier roads sometimes require more.
If your group stops showing up, the state can terminate the agreement and take down your sign; getting back in usually means a new application. Renewal at the end of your term is simple, often handled online, and groups with a steady track record can hold the same stretch of road for years.
Tax Deductions for Volunteers
You cannot deduct the value of your time, but if you itemize on your federal return you can deduct unreimbursed out-of-pocket costs tied directly to the volunteer work. Think gloves, sunscreen, or water bought specifically for a cleanup.
Driving to and from the site is deductible at the IRS charitable mileage rate of 14 cents per mile for 2026, and you can also deduct parking and tolls. You can use actual gas and oil costs instead of the standard rate, but not general car maintenance, insurance, or depreciation.1IRS. Publication 526 (2025), Charitable Contributions The 14-cent rate is set by statute and has held steady for years.2IRS. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile, Up 2.5 Cents
These deductions only matter if you itemize instead of taking the standard deduction, so most casual volunteers will not benefit. For groups running frequent cleanups and driving real distances, the mileage and supply costs are worth tracking.
