Dear Dr. Gridlock:

You recently asked whether any readers had experienced roadside scams. Last month I was rear-ended, and my car sustained damage in the rear and front.

The firemen who came to the accident scene told me they thought my car was drivable for a short distance. So I drove to the supermarket (in College Park) the day before my car was to go into the body shop.

As I was leaving the parking lot, two men in an approaching car waved their arms at me. I stopped and one of them said, "Ma'am, I fix your car in one day!" as he offered me a flier.

I burst out laughing because my insurance company had said it would take at least three weeks for the work to be done, and the body shop I had chosen had said it would take at least four weeks.

I told the man that, and he was undeterred.

I hope those fellows don't find any takers for their offer.

You were wise to be wary of strangers offering to "fix" your vehicle in a parking lot.

Can't Say It Enough

Dear Dr. Gridlock:

I read with interest the various solutions for thwarting tailgaters, and am appalled at the lengths the "tailgated" will go to. Not only does it exhibit their incredible lack of traffic sense, but it puts everyone at risk.

I am glad you pointed out repeatedly that the best thing to do is get out of the way as soon as possible.

Let me explain. The most common reason for tailgating is a person cruising in the left lane. If one is in the left lane, either keep up with the traffic (and please spare me the going-above-the-speed-limit song) or move to the right lane and have a less stressful drive!

With multiple lanes in the highway, it is simply inexcusable -- not to mention irresponsible -- to be driving in the left lane during non-congested hours, except to pass.

Perhaps those drivers need a Manhattan dose of signs that urge people to "Keep Moving!"

Use the left lane to pass.

Find a Wider Road

Dear Dr. Gridlock:

I have read your column hoping for a good solution for tailgaters. I live in Southern Maryland, and there are many two-lane roads in our area. Sometimes changing lanes is not an option for drivers down here.

My solution, which I have not seen addressed, is to turn on my emergency flashers when someone is driving way too close. The tailgater immediately slows down for about a mile but then will be right back on my bumper! I just turn on my flashers once more.

Short of increasing my speed to a dangerous level, I am not sure what to do to avoid the tailgater when there is no lane to change to. The roads are narrow and twisty, but drivers want to drive on them at more than the posted limit.

What do you think of turning on flashers to slow down a tailgater; and how should one get out of the way when there is no other lane?

Thanks for your help.

Many rural and suburban roads are two lanes wide, with no shoulders. That makes for challenging driving. Safety experts tell me it is unwise to use flashing lights while moving because it is not clear to other drivers what you are going to do.

You might try alternative, wider roads, if you can find them, or turning at the next cross street if you can't. It is unnerving to have a driver tailgating you; I understand.

This Is an Emergency

Dear Dr. Gridlock:

The traffic signal light at the intersection of Canal Road and Foxhall Road is turned in the wrong direction.

That causes confusion in case one is not paying attention to its mate on the other side of Canal Road.

Could you please ask the signal shop, or whoever takes care of the traffic signals in the District, to turn the direction of the signal so that it faces the traffic it is serving?

According to the District Department of Transportation, that is an emergency. Reports should be filed by calling the general complaint number, 202-727-1000. Operators are trained to immediately forward such complaints to the appropriate field crews, according to Bill Rice, spokesman for DDOT.

AAA Driver Training

Dear Dr. Gridlock:

You have in the past mentioned several driving schools in the Washington area.

Can you repeat any recommendations you or your readers made? This is for someone who has already been driving but needs further instruction.

My wife has driven in the United Kingdom and is now faced with getting a Maryland license. All things being equal, we would prefer a school or instructor in Bethesda or Rockville or adjacent areas.

I would be grateful for any comments or advice.

Everywhere a Tailgater

Dear Dr. Gridlock:

In your Oct. 7 column, you state that the best way to deal with tailgaters is to "put on my right turn signal and change lanes as soon as possible." Your statement implies that tailgaters tailgate only in the left lane. Unfortunately, it's not that simple.

In the D.C. area, tailgaters will tailgate in every lane, including in the far right lane. There are probably many reasons for their tailgating (me-first-ism, aggressiveness, traffic frustration, or my girlfriend's logic that "it's safe to tailgate because my car has anti-lock brakes"), but the fact remains that people will encounter tailgaters in every lane of traffic.

Therefore, my advice to drivers who are being tailgated is to try to put some sort of distance between you and the tailgater by any of the following methods:

1) Switching lanes and allowing the tailgater to pass you.

2) Switching lanes and slowing down so the tailgater is no longer directly behind you.

3) Temporarily speeding up (if there is no vehicle in front of you) to momentarily create space between you and the tailgater, thereby signaling to the tailgater that you don't like being tailgated.

4) In the case of a single-lane road, or when you are boxed in by traffic on all sides on a multilane road, slowing down slightly so that you create additional space between you and the vehicle in front of you. That gives you extra space to slow down and/or stop if an emergency situation occurs in front of you, while effectively doing the same for the tailgater, which decreases the chances of their hitting you from behind.

I've found those methods to be effective because they help put me out of harm's way without requiring that the tailgaters change their behavior, which is the only thing I can't control.

If one is continually tailgated in the right lane of a road, I suggest trying an alternative road. You want to end these confrontations as quickly as possible.

Disengaging Turn Signals

Dear Dr. Gridlock:

As to drivers forgetting to disengage their turn signals: A number of manufacturers have been putting in chimes that sound loudly when signals are left on. My two General Motors brands from 1997 and 1998 have them, although they don't ring until about a half-mile has passed.

I use turn signals always, city and highway, sometimes for a considerable distance on a highway readying to exit, and the chime occasionally has reminded me to be sure to cancel after the ramp.

Perhaps of greater benefit would be what my 1980 Suzuki motorcycle had: self-canceling turn signals that would turn themselves off automatically.

If Suzuki could do it on motorcycles 25 years ago, with a very small electronic control, carmakers ought to be doing it now in all cars.

Richard J. Sincoff

I've driven vehicles where the turn signal is automatically disengaged as soon as the steering wheel is turned slightly. An annoyance.
