(2) To the operator or the owner of a motor vehicle legally parked at the time of the accident;

(3) To the owner of a motor vehicle if at the time of the accident the vehicle was being operated without his permission, express or implied, or was parked by a person who had been operating such motor vehicle without such permission;

(4) To the operator or the owner of a motor vehicle involved in a collision with another vehicle, the operator of which other vehicle is found guilty of or pleads guilty to a charge of drunk driving, negligent injury or negligent homicide;

(5) To any person who would otherwise be required to file security, when the adverse party has been charged with negligent homicide; provided however, that this exemption shall not apply if and when the adverse party so charged has been tried and found not guilty; nor

(6) If, prior to the date that the commissioner would otherwise suspend license and registration or non-resident's operating privilege under R.S. 32:872, there is filed with the commissioner evidence satisfactory to him that the person who would otherwise have to file security has been released from liability or been finally adjudicated not to be liable or has executed a duly acknowledged written agreement providing for the payment of an agreed amount in installments, with respect to all claims for injuries or damages resulting from the accident.

However, notwithstanding any of the provisions of this Chapter, the commissioner shall never suspend any registration of any owner of a motor vehicle involved in any accident where under the law of this state such owner is not legally liable for damages arising from such accident.
