Q It seems to me that you give out a lot of great advice, but I rarely read about the behavior you have changed. I propose a day dedicated to feedback about how your column has changed readers' driving behavior.

A Really. Such as ...

Q I'll be glad to start it off.

While I always strive to use my turn signals, I was struck by two things I read in Roadshow about them. One comment was from a motorcyclist who asked that four-wheelers let their turn signals blink at least three times before changing lanes. The other was from a cop who said that he ticketed drivers who didn't signal soon enough. I now count three blinks before changing lanes.

Bill Fitzgerald

A So do I. Folks, how has advice from traffic cops, safety officials, Roadshow readers and me affected your driving? I know I tend to drive more slowly and in the far right lanes after cranking out this column.

Q Is it legal for a bicycle to split lanes? I've seen it on Highway 9 and it scares me.

Cathy Compo

A Says D.J.-the-CHP-Man:

"All laws in the vehicle code apply to bicycles, and it states that a bicycle has to stay to the right edge of the roadway unless passing slower vehicles or another bicycle (so NO two bicyclists riding side by side). A bicyclist could be cited if passing too close or too fast by a stopped or slowly moving vehicle or for unsafe speed for conditions. If the bicyclist is passing to the left of the center line, lines or double lines of the roadway then, it's a violation.

"But if the bicyclist is passing safety in the same lane, then no problem" splitting lanes.

 

Q We regularly drive Highway 80 through Sacramento and notice they've widened the highway in both directions. When are the new lanes scheduled to open? The westbound lanes appear to have been completed months ago.

A This is the I-80 "Across the Top" project that will not be completed until the fall of 2014. Caltrans says although the lanes look complete, crews are still working to repair different areas between Watt Avenue and the Sacramento River, adding about 10 miles of carpool lanes and paving.

Q And are there any plans to add lanes on Interstate 80 between Davis and West Sacramento? Backups in both directions are pretty severe.

Steve Malmquist

A Alas, no.

Q The letter from Alan Newman of Milpitas about going to court over a traffic ticket brought to mind an experience I had about 50 years ago for going 40 mph in a 25 zone on a four-lane street in Santa Clara.

I went to court with the defense that I traveled that route each Monday to a voice lesson in Palo Alto, particularly since the street was at that time deserted of pedestrians and cars. There were literally no cars coming or going.

Then while waiting to go into court I wrote this to the judge. "When driving to this court appointment I was on Park Avenue going toward The Alameda, which is a 25 mph zone, paying particular attention to staying within that speed limit, not wanting to get another ticket, when all of a sudden a low-flying bird swooped down in front of my windshield, and I barely missed hitting it. So I have to assume that the 25-mile-an-hour speed limit is 'for the birds.' "

The judge dismissed my case (the officer had not come to court). But when he read my note, which I handed him after the decision, he broke up in laughter. I'm sure others in the courtroom wondered what was in my note.

A few months later I noticed that the speed limit on that street had been changed to 35. Win some and lose some. I won that one!

Alma Taylor

A Yes, you did. Alma is now 90 and has a great sense of humor.

Q You wrote about the new white, oval stickers for cars that show the miles for distance runners. For triathletes, it is 140.6. Full marathon runners have 26.2 and half marathoners have 13.1. The one I have is 0.002, which is the distance from my couch to the refrigerator.
