What happens after I had just gotten my driver’s license suspended for none driving violations and had missed a payment?

The police officer can search you and your car without your consent if he has probable cause to believe that you may be armed or that your car contains evidence of a crime. The police officer does not have to read your your rights, even if he arrests you. The only reason a cop reads someone their rights is if they want to question them while in police custody and use that testimony against the person in court. If the evidence of the crime is very obvious, the police officer won't bother reading someone their rights. The police can tow your car or the purpose of doing an "inventory search" - nothing illegal about it. I suggest that you hire a lawyer to represent you for the marijuana possession charge. An attorney can probably get the charge dismissed or amended to a lesser offense.
