The Criminal Uniform Traffic Citation: The Right to a Massachusetts Clerk Magistrate Hearing After a “Routine” Traffic Stop

By Attorney Joseph Serpa | Georgetown University Law Center | 30 Years Massachusetts Criminal Defense

If Massachusetts police handed you a Uniform Citation for a criminal motor vehicle offense — negligent operation, leaving the scene, operating after suspension — and did not arrest you, you have a four-day window to request a private clerk-magistrate hearing. Missing that deadline waives your right and results in a direct criminal complaint being issued against you.

The 4-Day Statutory Deadline

Under Massachusetts General Laws Chapter 90C, Section 3(B)(2), a motorist accused of a misdemeanor motor vehicle offense who is not arrested at the scene must be issued a Massachusetts Uniform Motor Vehicle Citation. To exercise the statutory right to a pre-arraignment show cause hearing, the defendant must sign and physically submit the citation to the applicable District Court clerk-magistrate within four days of the violation.

Failure to submit the citation within this strict 4-day window is a waiver of the right to a hearing. If the deadline is missed, the court is authorized to issue a criminal complaint directly and mail a summons for an arraignment.

Distinguishing Civil Infractions from Criminal Applications

A standard Massachusetts Uniform Citation is used for both civil infractions and criminal applications. A citation becomes a criminal instrument when the issuing law enforcement officer checks the “Crim” (Criminal) box and the “Criminal Application” box on the front of the ticket.

These checked boxes indicate that the police department is formally applying for a criminal complaint against the operator. This cannot be resolved by paying a civil fine. Attempting to pay the citation online or by mail as if it were a civil ticket will not stop the issuance of a criminal complaint.

Common Misdemeanor Motor Vehicle Offenses

In Massachusetts, police are generally prohibited from making immediate warrantless arrests for certain motor vehicle misdemeanors unless specific statutory exceptions apply (such as suspected Operating Under the Influence under M.G.L. c. 90, § 24). The most common misdemeanor offenses prosecuted via a criminal citation and subsequent clerk-magistrate hearing include:

• Negligent Operation of a Motor Vehicle (M.G.L. c. 90, § 24(2)(a))
• Leaving the Scene of Property Damage (M.G.L. c. 90, § 24(2)(a))Serpa Law Office
• Operating After Suspension or Revocation (M.G.L. c. 90, § 23)
• Uninsured Motor Vehicle Operation (M.G.L. c. 90, § 34J)

The Clerk-Magistrate (Show Cause) Hearing Process

If the citation is submitted within the 4-day statutory limit, the relevant District Court will schedule a clerk-magistrate hearing, often referred to as a “show cause” hearing. Governed by M.G.L. c. 218, § 35A, this hearing is a private, pre-arraignment procedure held before a court clerk-magistrate rather than a judge.

The sole legal standard at this hearing is whether there is “probable cause” to believe the defendant committed the alleged offense. The rules of evidence do not apply. The police prosecutor presents a narrative of the incident, and the defense is permitted to cross-examine witnesses and present exculpatory evidence.

Outcomes and CORI Implications

Because the clerk-magistrate hearing occurs prior to formal arraignment, the proceedings are not entered into the defendant’s public Criminal Offender Record Information (CORI).

If the clerk-magistrate finds no probable cause, the application for a complaint is denied, and no criminal record is generated. Alternatively, magistrates have the administrative authority to hold the complaint in a pending status for a specific period (typically six months or a year) prior to dismissal, provided the defendant incurs no new legal issues. At the end of the period, the application is destroyed and there is no criminal record created. If probable cause is found and the magistrate authorizes the complaint, the case proceeds to a formal arraignment in open court, at which point the charge is permanently entered onto the defendant’s CORI.

Key Takeaways:

(1) You have exactly 4 days from the citation date to request a clerk-magistrate hearing under M.G.L. c. 90C. (2) A criminal citation cannot be paid as a civil fine — attempting to do so will not stop a criminal complaint. (3) The hearing is private — no CORI entry is created unless the magistrate issues the complaint. (4) Negligent operation, leaving the scene, and operating after suspension are the most common offenses handled this way.
