OffensesProcedure on Equipment and Registration Violations
Section § 40150
When a vehicle is found to be unsafe or lacking required equipment, the driver may receive a notice or complaint. This notice might require the driver to show proof in court that they've fixed the problems to meet the law's standards.
Section § 40151
If a police officer finds that your vehicle's lighting equipment doesn't meet safety standards set by the California Highway Patrol, they will tell you to remove it within 24 hours. If the lighting equipment generally meets standards but is improperly adjusted or otherwise not in compliance, you have 48 hours to fix the issue.
Section § 40152
If you're caught with a vehicle that isn't properly registered according to this code, you'll get a notice to appear in court or a complaint will be filed. To avoid penalties, you have to show the court proof that the vehicle is now registered, the necessary fees are paid, or the vehicle is junked. The court won't drop the case until you provide this proof.
Also, if you're trying to prove registration, a four-day nonresident commercial trip permit won't count as acceptable proof.
