Dear Dr. Gridlock:

Why aren't Metrobuses required to use the HOV lane on Route 50? The gasoline savings alone should make it mandatory.

I'm sick of sitting in traffic and spending additional commuting time while the HOV lane is wide open. What is the purpose of this lane if eligible vehicles don't use it?

Route 50 is bad enough during rush hour without people entitled to use the HOV lane clogging up the regular lanes.

Pam Hanlon


Metro's sole bus route on Route 50 is the B-22, which runs between New Carrollton and Bowie. The reason the bus doesn't use the left-hand HOV-2 lane is because it travels only a short distance on Route 50 and would have to cross four lanes to get to the HOV lane, then four lanes back to exit on Route 197 at Bowie. It's a safety issue, according to Metro spokesman Steven Taubenkibel.

Signs Slowing Traffic

Dear Dr. Gridlock:

I was driving south recently on Interstate 95 in Howard County in freely moving traffic, but as I approached the exit for Route 198, traffic came to a very sudden stop. Lots of screeching tires, and one car even veering off onto the shoulder to avoid hitting another.

The apparent cause of the sudden slowdown was an electronic overhead sign warning of delays and slow traffic approaching the exit for Interstate 495.

I took note, as that was my intended destination, and continued on my way.

Immediately after the sign, traffic picked up again and was moving freely . . . until another electronic overhead sign appeared right before the exit for I-495 with the same "traffic warning."

Once again, traffic came to a drastic halt as motorists hit the brakes to read the sign. And, just as before, as soon as I had passed under the sign, traffic resumed its easy flow, even as I exited onto I-495.

So, my question is, who is in charge of deciding when and what messages should be posted on those overhead signs? I can certainly see their utility in alerting motorists of accidents and road closures, but in this case they seemed to cause more traffic problems than they prevented.

Amy Pottberg


The Maryland State Highway Administration is in charge. The agency monitors state highways from a command center near Baltimore-Washington International Airport. This matter has come up before, and the state says the signs are serving their purpose in getting drivers to slow down.

I'm not sure how the state could do it better. Thoughts?

Two-Plate States

Dear Dr. Gridlock:

Has Maryland stopped requiring front license plates on cars? I have noticed an increasing number of cars with rear Maryland license plates but no front plates.

When did Maryland change the rule, if it did? And if front plates are still required, why isn't the law enforced?

Ben Kaufman

Silver Spring

Maryland, Virginia and the District all require plates front and rear. Some other states do not require a front plate, and I wonder if there is some confusion.

I haven't received other letters suggesting that this is a widespread problem. Maryland law enforcement wrote 3,096 missing license plate violations for the fiscal year ending June 30, 2004, and 2,634 for the fiscal year before that. But those statistics do not distinguish between missing front plates and rear plates. The fine is $55, with no court costs.

If you see a violation, hit #77 on your cell phone, and police may respond, depending on their availability.

Is anyone else seeing one-plate cars in a two-plate state?

Teenage 'Panhandlers'

Dear Dr. Gridlock:

I would like to raise the topic of panhandling on Prince George's County streets, specifically at the intersection of Allentown and Brinkley roads. The last I heard, panhandling was illegal in the county, yet there seems to be no enforcement of the law.

On any given Saturday, it is common to find high school students wading through traffic, panhandling for change, presumably for a charitable cause.

I believe the schools' practice of sending children into the streets begging for money is appalling and unsightly. I cannot believe that the faculty and parents are teaching our future leaders how to beg for money instead of teaching students how to earn.

What happened to bake sales, car washes and talent shows? What happened to parents and teachers seeking sponsorships through local business and churches? Will it take a child getting hit by a car while panhandling for the police and county council to respond?

Fletcher White

Fort Washington

This has been a recurring problem in Prince George's County. Panhandling in the streets is a violation of county law, and police tell me they take it seriously.

"Feel free to call us, especially if young children are involved," said Cpl. Debbi Carlson, a spokeswoman for the Prince George's County Police Department.

The number to call is 301-333-4000. If there are still chronic problems at a certain location, go to the nearest police district station and talk to the commander or duty officer.

I share your concern about youth in traffic. It is a dangerous way to raise money.

Parents Are Best Teachers

Dear Dr. Gridlock:

My 15-year-old son recently finished a driver's education program with a well-known driving school to satisfy a requirement for obtaining a driver's license.

Imagine my surprise upon hearing that his teacher had not taken him on the Capital Beltway or Interstate 270, both of which are less than five miles from where we live.

That experience, it turns out, is not unique to my son. Almost all of his peers received the same inadequate driving instruction.

Granted, the responsibility for ensuring that a teenager is ready to drive does fall predominantly on the shoulders of parents, but in light of the current spate of teenage deaths due to poor driving skills, it would behoove driving schools, and the authorities who should oversee them, to take their jobs more seriously.

Mercia Ordman Rindler


You would think the state legislatures would require such schools to provide certain basic instruction, such as practice on an interstate highway, but that's not the case. The legislators are asleep when it comes to driver education standards.

For years I've cautioned readers to expect little from these commercial driving schools. By all means, do not think your teenager is ready to drive solo just by "graduating" from one of these schools. Teenagers should receive their primary driver's education from their parents, over a long period, with training in every conceivable driving situation (including interstate highways). Only when parents feel their child is ready to drive solo should they allow a driver's license.

The commercial driving schools provide certificates necessary to get a license. Expect nothing more.

Mind Medical Needs

Dear Dr. Gridlock:

I read the letter from Sonja Dieterich [Dr. Gridlock, July 7] regarding the teenager who was drinking juice on the Metro under the watch of a Metro employee.

My daughter has Type I diabetes, which she treats with insulin and regularly timed meals and snacks to prevent low blood sugar.

A side effect of insulin is a sudden drop in blood sugar that can rapidly lead to coma and death. The treatment is a drink of juice, sometimes followed by food -- immediately, whenever the problem strikes. It is dangerous to wait.

Perhaps the teenager had sought the help of the Metro employee while she got her blood sugar under control. Perhaps the employee was monitoring her to be sure Metro didn't have a medical emergency on its hands.

A diabetic experiencing low blood sugar may be irritable or unable to communicate. Because of my personal experience, when I see someone eating or drinking inappropriately, I give them the benefit of the doubt.

Linda Gordon

Silver Spring

That's a good way to cope with eaters and drinkers who drive some Metro riders bonkers. I am so sorry about your daughter's disease. It's pernicious and common. I have it, too.

Confronting Scofflaws

Dear Dr. Gridlock:

My most recent experience with people eating in the subway system was unfortunately not as benign as Linda M. Cajka's [Dr. Gridlock, July 7]. On the Union Station platform a couple weeks ago, I noticed a woman and two teenagers consuming sodas and snacks.

When I asked if they realized that this activity was illegal, the woman became defensive and hostile.

I did not alert the station manager, which I have done on previous occasions, as there was a delay on the Red Line at the time, and I figured the staff already had enough to deal with.

I do not intend to ignore future scofflaws, but there are reasons for hesitating to approach them directly.

Patricia Richter

Silver Spring

I understand your frustration, but it might be better to alert Metro personnel. You might get into a confrontation that ends badly.

Police Presence

Dear Dr. Gridlock:

Law enforcement officers in our city certainly don't deserve to be reported for parking illegally to grab a bite to eat or a cup of coffee [Dr. Gridlock, July 7].

I support any type of police presence, even double-parked police presence.

It is ludicrous to expect officers to park legally while conducting non-emergency business. If, by parking illegally, officers are able to patronize local establishments and increase their on-street presence, I fully support the practice.

We should be doing everything we can to support these officers -- not griping about a motorcycle on the sidewalk.

And your request to readers to pass along information about offending vehicles for police to investigate? Please. These men and women deserve far more respect, support and accommodation.

Ed Farley


Well, that is certainly a counterpoint.

The voices I have heard on this subject are mad that police park illegally. They don't like police doing something they can't do, especially when police are not on an emergency call.

However, now that you mention it, if I were a downtown merchant, it would be okay by me if police parked on a sidewalk near my front door or picked up a cup of coffee nearby.

We disagree over the matter of double parking, however. We don't want police on a non-emergency call blocking a lane of traffic. We want police to move traffic along, not block it.

Thanks for your views, Mr. Farley.
