U-turns are often prohibited for various reasons. Sometimes a sign indicates the legality of U-turns. However, traffic regulations in many jurisdictions specifically prohibit certain types of U-turns. Laws vary by jurisdiction as to when a U-Turn may or may not be legal. Examples of jurisdictions with codified U-turn prohibitions include the Provinces of Alberta and British Columbia and the State of Illinois.[1] In Alberta, U-Turns are prohibited in certain circumstances, for example (ref. Alberta Regulation 304/2002, Division 7):# j6 |4 A" j6 I+ l _
