Thank you for that information. The question was how to get the ticket dismissed outright. For any traffic infraction, the burden of proof is on the state to prove guilt. So, for any given case, it's possible that a defendant could literally say nothing and have the ticket dismissed if the state's evidence isn't sufficiently persuasive. Naturally, every case is going to be different, so I am not suggesting that this or any other defense is necessarily right or wrong for you.
A discrimination defense would be without merit, first because Beverly Hills has the right to enforce the laws on the books even if other jurisdictions do not, and second because discrimination in law enforcement matters itself is not illegal---it is only illegal in certain circumstances, such as situations involving discriminating based on race, color, religion, ethnicity, gender, etc. The penal code discriminates against criminals. It is not illegally discriminatory for a city to enforce state law simply because others do not.
That said, not being able to stop safely generally is a valid defense to a failure to stop citation
. If an intersection traffic signal is timed in a way that a driver can't stop safely, or if traffic conditions are such that a driver (through no fault of his own) , then there is a factual basis for acquittal. The law generally does not force the choice of either getting injured or getting a ticket (fortunately).
How to defend yourself is up to you, but I will alert you that it is usually a mistake to fight a ticket in writing if you can appear in person. A judge can ask questions and details can be explained in person, plus there is just a human aspect of dealing with someone in person that isn't achieved in writing, especially when the judge reviewing the written defenses is pouring over dozens per day, many appearing identical. I'm certainly not saying that a written declaration isn't a valid option or that it won't be successful, but consider a personal appearance if that is an option for you.
