If you refused to sign a traffic ticket then you could be dentained and could be facing a night or two days in jail. By signing it it doesnt means that you broke the law. It only means that you are going to show up for court. In a few states some officers sign RTS (refused to sign). I hope this answered you question.
Yes, ANY ticket is considered an arrest. You don't have to be taken in to be "arrested". This is a misconception by people who are not law enforcement.
The officer can ticket you for the traffic violation, he or she can arrest you if there are mitigating circumstances.
arrest warrant for failure to pay.
The unpaid ticket causes the court to issue a warrant for your arrest. It's unlikely that California would extradite you from Texas for an unpaid traffic ticket, but if you go back to California, you are subject to arrest at any time.
in most states the fine will double and a bench warrant for your arrest will be issued.
Sounds to me like the case for a new ticket or even arrest. Something is not kosher.
Yes. A signature is only your verification that you have received the ticket. Actually, a refusal to sign can and normally DOES result in immediate arrest and transport before a judge. If people could not pay a ticket simply by not signing them, no one would EVER get one!
When they write you a ticket, but you are not arrested. Examples of this are most traffic violations, i.e. a speeding ticket. More serious crimes will be an arrest, not a citation.
Most agencies will issue a warrant to arrest.
No, tickets don't expire. If you get a ticket, you get a ticket. In CA, your ticket requires that you appear in court either fight it or pay it and receive your sentencing and traffic school if available. But if you evade your ticket and dodge court, a warrant can and probably will be issued for your arrest. My advice, just pay it.
A warrant is issued for your arrest. If stopped your car will be impounded and you will be taken into custody.
A warrant will not be issued for your arrest for an unpaid parking ticket. If you have an unpaid speeding ticket, they may issue a warrant for your arrest.
