After you sell a car in Boise: the four things left, and the letters that can follow
The buyer has the car. You have the plates, a signed bill of sale, and five days. This page is the rest of it: the release to file, the insurance to change, what the state's insurance-verification letter means if one arrives, and how to identify the toll-fine impersonation described in the state’s alert.

Your plates are in your hand, and they stay there
Idaho Code 49-431 keeps the plate with the seller, and ITD's release form says it in a note: "*Note: Remove your vehicle license plates upon sale or transfer! You may transfer the plates through a DMV office to another vehicle you own." Registration fees are not refunded, so the value left in the plate is the time on it; ITD 3438 lets you keep the plate number or the remaining time for your next car. If you have no next car, cancel the registration on the same form so the record closes.

File the release within five days
The Notice of Release of Liability, ITD 3858, is the seller's filing under Idaho Code 49-526, due within five days of delivery counted Idaho's way, online with the VIN and title number or on paper with $3.50. The release page has the statute, the form, the count and a calculator. File promptly after the sale and save proof that your notice was submitted.

Insurance: tell the insurer, and know what the state's letter means
Tell your insurer the sale and handover dates and ask it to confirm, in writing, the date the policy on that car ends. Idaho checks insurance against registrations by computer, and the state’s insurance-monitoring program can send a notice about a registered car. ITD's page describes the check: "Vehicle owners without vehicle insurance coverage for two consecutive months will receive a warning and be given 30 days to provide proof of insurance or obtain an exemption before their vehicle registration is suspended." After a suspension: "You will have to provide proof of insurance and pay a reinstatement fee of $75."
The statute the program runs under gives different periods from the page: Idaho Code 49-1234 says the initial notice "shall provide sixty (60) days for an owner to comply with the financial responsibility requirements or to notify the department of exemption", and the final notice "shall provide ten (10) days for an owner to comply with the financial responsibility requirements or to notify the department of exemption before suspension". The page says 30; the statute says 60 and then 10. Both are printed here because both are the state's, and the safe reading is: answer the letter by the date printed on it.
For a car you have sold, ITD's insurance page gives the route in one line: "Recently sold or got rid of a vehicle? Please fill out a Release of Liability form. You will need the VIN and Title Number." Nothing on that page or in the statute says the release cancels a notice already sent, so if a letter arrives, respond to it with the sale date and your release confirmation, and keep the reply.

A text about a toll: Idaho has none
Check which road and agency a toll message claims to concern; an Idaho-sounding demand deserves particular scrutiny. The Idaho Transportation Department's scam alert: "Idaho does not have toll roads, and ITD does not issue toll fines." A message claiming an Idaho toll-road charge or an ITD toll fine conflicts with that statement. Do not use its payment link. A car can travel outside Idaho, so verify any claimed out-of-state charge independently with the named toll agency.

A ticket or a tow notice for a car you sold
If a parking ticket or impound notice reaches you after the sale, check the date and vehicle against the records you kept. Your answer is the paperwork you kept: the signed bill of sale with the date, and the confirmation of your release filing, which records the buyer's name and address and the sale date with the state. Send copies to the issuer and keep its reply; the filing confirmation documents what you reported but does not guarantee that a notice is automatically withdrawn. For an impound notice after a sale, send the issuer your sale and filing records and confirm what it still needs. The impound page explains how to identify the holder and check release requirements.

What to keep, and for how long
Keep together: your copy of the signed title assignment or a photograph of it, the signed bill of sale, the release-of-liability confirmation, the insurer's written end date, and the buyer's name, address and licence details. This guide has not established an agency retention period for these private-sale records. Keep them available while the title transfer or any related notice remains unresolved.
After-sale questions
When can I cancel the insurance?
Once the car has left and your release is filed, tell the insurer the sale date and get its end date in writing. Confirm cancellation with your insurer and keep the release record; respond separately if the state sends an insurance notice. ITD: vehicle insurance.
I got a text about an unpaid toll on my old car.
Idaho has no toll roads and ITD issues no toll fines. A demand claiming either is the impersonation described in ITD’s alert. Verify an out-of-state toll claim with that agency independently. ITD scam alert.
Do I get a refund on the registration?
No; fees are not refunded. Move the plate or the remaining time to your next car with ITD 3438. Idaho Code 49-431.
