Q How about a contest to pick driving tips for Caltrans' illuminated signs? I submit "Merging -- it's like a zipper."

Joanne Smith

A Not even close to the top choice.

Q I have seen a few signs on freeways that advise slower traffic to keep right but they are few and far between. Have they considered including the message for slower drivers to keep right on the lighted signs? There seems to be no valid argument against it. What's the problem?

A.J. and many more

A It works for me and for so many of you but Caltrans has no plans to run this message, saying there are already black and white signs posted along our freeways advising road boulders to move right.

Q While driving through Arizona, we were amused by the anti-drunken driving slogan on the electronic signs: "Drive Hammered. Get Nailed."

A A DUI ticket can run as much as $10,000 by the time you pay bail, fines, fees and insurance. More if you hit anything or hurt anybody.

Q I think it is time for a new slogan for the info signs on the freeways, especially with the threat of fire under these extreme dry conditions:

Extreme Fire Danger

Keep Your Butts to Yourself

Flick it -- Get a Ticket!

Daniel Chapman

Santa Clara

A Another one of my favorites.

Q I have to disagree with you and some of your readers. I think it's distracting, unnecessary and kind of annoying to have messages on the changeable freeway message signs that don't pertain to specific hazards that aren't normally there. I wish they would stop with "Slow for the Cone Zone," "Click It or Ticket" or any other asinine rhyming phrase that Caltrans probably spent too many tax dollars on some consultant to come up with. Even "Report Drunk Drivers, Call 911", and the "Minor Traffic Accident? Pull Over" don't qualify as special messages.

If you want to convey those messages, put up regular signs, don't imply that there is some special traffic advisory in effect. In fact, I'm disappointed that these signs aren't used more often for the types of advisories that they were designed for, such as weather issues, accidents, lane and road closures due to construction, etc.

A OK.

Q In May an electronic highway sign was seen on Interstate 93 in a bid to get notoriously aggressive Boston drivers to use their turn signals. Massachusetts officials tried to put the message into terms that only they would understand:

"Changing Lanes? Use Yah Blinkah."

Chuck Martin

San Francisco

A Gotta love it. That campaign was deemed so successful that Massachusetts is now holding a contest to come up with additional messages to show drivers of the state.
