Miss this on a ticket or after a crash, and the ugly version is simple: you turned right at a red light, someone got hit, and now you are dealing with a citation, insurance blame, and possibly a personal injury claim. A right turn on red violation means making a right turn while the light is red without following the rules that make that turn legal. In most places, including Kansas, a driver may turn right on red only after coming to a complete stop, checking for a sign that says the turn is prohibited, and yielding to pedestrians, cyclists, and cross traffic that has the right of way.

What to do in real life is straightforward: stop fully behind the line, read the sign, look twice, then turn only when the way is clear. Rolling through the light, cutting off a pedestrian, or turning anyway where posted "No Turn on Red" can all lead to the same basic violation. On Kansas roads, including state and federal highways patrolled by the Kansas Highway Patrol, that ticket often shows up after a crash report.

For an injury case, the violation can matter a lot. It may be evidence of negligence, though it does not always decide fault by itself. Kansas follows comparative fault under K.S.A. 60-258a (1974), so blame can be divided. If hail, glare, or a cracked windshield limited visibility, that may explain conditions, but it usually does not erase the duty to stop and yield.
