The law does require that warning signs be posted, but the law gives cities the choice in where to post the signs and the law is vague as to how CLOSE to the intersection the signs have to be posted (provided the city decides to post the signs at the intersection). According to the Cal Trans design the signs must be at least 30 inches wide by 40 inches high and 6 feet off the ground but there is no requirement as to the distance a sign must be posted in relation to an intersection. Warning signs will not always be posted right at an intersection so drivers should be on the lookout for such signs when entering a city or exiting from a freeway off ramp. If you do get a red light photo ticket you should go back and search for warning signs and if you can’t find any where they are supposed to be or the signs are there but they are not the right size or are blocked or damaged in such a way that they are not visible, then take photographs so you can dispute the ticket. If the signs weren’t posted in accordance with the law (VC§ 21455.5(a) (1) ) then as a result you weren’t given the required notice and more importantly, a foundational requirement (warning signs) for the camera enforcement system is lacking. - blog submitted by ticketbust.com, helping drivers contest and dismiss their traffic tickets.
