You must notify the DMV with 5 days, if you:

  1. Paint your vehicle a different color.
  2. Sell or transfer ownership of your vehicle. ✓
  3. Receive a traffic violation.

Answer: B. Sell or transfer ownership of your vehicle.

You must tell the DMV within five days when you sell or transfer ownership of your vehicle.

Why this is the answer

The handbook says that after you sell a vehicle, you have five days to notify the DMV by filing a Notice of Transfer and Release of Liability. That form tells the state the car is no longer yours. The same section gives a different deadline for the buyer, who has 10 days to move ownership into their own name. So the five-day notice belongs to the seller, not the person buying.

Why the other answers are wrong

Remember it

Selling is the seller's job: the seller reports the transfer to the DMV within five days, while the buyer has 10 days to put the car in their name.
