I rec'd a ticket for running a red light in Chicago. The ticket photo shows an amber time of 3.0 seconds.

I don't know if there is law on the subject but as a matter of science the amber light has to be keyed to the actual speed limit. If it's too quick the ticket may be invalidated. You can ask for the engineering studies for the light you supposedly ran to see if they support the amber light time.

Negotiating a resolution acceptable to you given the circumstances of your case will take an attorney familiar with the policies and procedures of the court to increase that likelihood.

Check with a lawyer in your locale to discuss more of the details.

Good luck to you.

God bless.
