Dear Dr. Gridlock:

My daughter got a $50 traffic ticket for a "yellow light violation" in the District of Columbia last week. She explained that she felt it was safest to proceed through the intersection because the traffic light had turned yellow just as she entered it.

The officer said she had time to stop before proceeding through the intersection. The policeman chastised her for not knowing the rules. I never heard of this.

Could you please clarify the situation?

We all face these choices in our daily driving, and they often require instantaneous decisions: to gun through the intersection, or to jam on the brakes. It's a judgment call by the motorist, and one by the officer on the scene. A lot of us have no doubt violated this law.

Under District of Columbia traffic law, a vehicle facing a steady yellow light "shall stop before entering the nearest crosswalk of the intersection, unless so close to the intersection that a stop cannot safely be made."

Because your daughter felt she could not stop safely, appealing the ticket to the D.C. Bureau of Adjudication might be in order.

Dr. Gridlock's assistant, Jessica Medinger, found that Virginia also has a law that prohibits running yellow lights. Most of the time, officers are not going to issue citations unless the motorist accelerates to make it through the intersection on yellow, according to Lucy Caldwell, spokeswoman for the Virginia State Police.

Maryland does not have a yellow light law, and as long as motorists clear the intersection before the light turns red, they should be okay, according to Maryland State Police.

Officials in all jurisdictions will cite drivers for running a red light if they are in any part of an intersection when the light turns red.

The way people drive in this metropolitan area, it is sometimes dangerous to stop on a yellow light for fear of being rear-ended by some maniac. The instant answer to that circumstance is to go on through. Any comments?

METRO LOST AND FOUND

Dear Dr. Gridlock:

What happens to the lost articles turned in to Metro that are never claimed?

Metro keeps lost items for 30 days, then applies a 15-day grace period after which:

* Inexpensive items are returned to the finders (Metro employees excluded) or, if refused, donated to charity.

* Expensive items are auctioned, with proceeds going into the Metro fund.

"We do everything possible to track down the owners," said Cheryl Y. Johnson, spokeswoman for Metro.

Most frequently found items: books, purses, wallets, umbrellas, computers.

Most bizarre items: horse saddle, wheelchair (both returned to owners).

Most money found: $2,600 in a woman's purse (also returned to owner).

Average number of found items turned in each year--2,200.

The Metro number to call to turn in a found item, or report a lost one, is 202-962-1195.
