Yes, you should contest the ticket. An error in the vehicle description—such as listing a 2001 model year instead of the correct 2002—can be a material mistake that may lead to dismissal.
Traffic citations must accurately identify the vehicle involved. A discrepancy in the model year undermines the ticket's reliability as evidence. Courts often consider such errors grounds for dismissal, especially if the mistake could cause confusion about the vehicle's identity.
If the judge agrees the error is material, the ticket may be dismissed. You would avoid the fine, traffic school, and any license points. Even if not dismissed, the error could weaken the prosecution's case.
Traffic laws and court procedures vary by jurisdiction. Consider consulting a local traffic attorney for personalized advice.
