Twin Falls, ID Parking Rules: Curb Color Rules (2026)

Section 9-6-20 of the Twin Falls City Code, adopted by the Twin Falls City Council, lets the city regulate parking with signs and with paint. Paragraph (A) authorizes signs establishing areas for no parking at any time, loading zones, limited time parking and handicapped parking. Paragraph (B) then allows the city to use curb markings as substituting or supplemental to standard signs, and states that where signs are not used, the intended meaning should be stenciled on the curb.

The color code is fixed. No Parking Any Time is red curbing with black stenciled letters, if any. Loading Zone is yellow curbing with black stenciled letters, if any. Limited Time Parking is green curbing with white stenciled letters, if any. Handicapped Parking is blue curbing with white stenciled letters, if any. A painted curb is therefore enforceable even without a sign, because paragraph (C) says that when official signs or curb markings regulating parking are used as authorized, no person shall park a vehicle upon a street in violation of the sign or marking.

Paint also controls how a vehicle sits in a space. Under paragraph (D), the city may cause lines or markings to be painted or placed upon the curb, or the street adjacent to it, designating parking spaces, and each vehicle must park within the lines for that space. It is unlawful to park across a line or in a position that is not entirely within the designated space. Paragraph (E) requires a vehicle in such a space to be parallel or diagonal to the curb in accordance with the markings.

The code assigns the painting authority to the city. It does not authorize a resident or business to paint a curb on its own, so private curb painting is not covered by anything in this section.
