You can request your trial to be done by mail, yes this is legal and if you truly want to get out of a speeding ticket or any other tickets or fine. Just do it the trial by mail and always postpone it for a greater chance of the officer just letting you win it. The source for all my information is from a lawyer, also check your local laws or state laws about this, thank you maggoty as it depends.
