WASHINGTON – Miriam Singer’s license plate reads “MS” and nothing more. The letters are her initials.

But ABC 7 reports Singer — an 87-year-old Baltimore resident — has received D.C. speed camera tickets for license plates reading “MS ALF,” “MS G” and “MS MAD” in the past four months — even though she said she hasn’t even driven in the District.

ABC 7 says speed camera tickets are supposed to be reviewed by a person before being issued. Buel Young, spokesman for the Maryland Motor Vehicle Administration, said it’s up to police to double-check every ticket for accuracy before it’s sent out.

The tickets since have been voided by the Metropolitan Police Department, ABC 7 says. MPD spokeswoman Gwen Crump attributed the mistake to human error.

Crump also said some Maryland tags require special handling. Young said he wasn’t sure what Crump meant by that.
