Summary

Abandoned vehicles are governed by Idaho Code Title 49, Chapter 18. Abandonment on any highway or on public/private property without consent is prohibited (IC 49-1801). A property owner may have an unauthorized vehicle removed if the property is posted with a conspicuous towing notice (IC 49-1806).

City-specific rules exist: Boise has its own abandoned vehicles rules that differ from Ada County's county-level regulations. If you live in Boise, check the city-specific page instead.

Any person having possession or control of real property, including commercial property, who finds an unauthorized vehicle standing on his property is permitted to have the vehicle removed or booted if there is posted on or near the property in a clearly conspicuous location, in large print, a sign or notice that unauthorized vehicles will be removed or booted at the owner's expense and designating the name of the towing firm.

Full Breakdown

Idaho Code 49-1801 prohibits abandoning a vehicle on any highway or on public/private property without consent. Under Idaho Code 49-1806, a person controlling real property (including commercial property) may have an unauthorized vehicle removed or booted if a clearly conspicuous sign in large print states unauthorized vehicles will be removed at the owner's expense and names the towing firm; on non-commercial property, an owner may contact a tow company even without posting. Notably, expired or improper registration alone does not make a vehicle unauthorized. In Ada County, report abandoned vehicles on public roads to the Ada County Sheriff.

Violations & Fines

Vehicles abandoned or left unauthorized may be towed, booted, and impounded at the owner's expense under Idaho Code 49-1806; abandonment itself is prohibited under 49-1801.

Frequently Asked Questions

Can I have a car towed off my property in Ada County?
Yes. Under Idaho Code 49-1806, post a clearly conspicuous sign naming the tow firm and stating unauthorized vehicles are removed at the owner's expense; non-commercial owners may call a tow company directly.
Can a car be towed just for expired registration?
No. Idaho Code 49-1806 states no vehicle is unauthorized and subject to removal solely because of expired or improper vehicle registration.
