Q What do you think of the proposal to drop the maximum blood alcohol level from 0.08 to 0.05 percent for drunken driving?

A I like it and here's why: Although any change is a long shot and at best many years away, it raises awareness that you don't need to be legally drunk to be an impaired driver. State officials say there has been no push to lower the blood alcohol level either in the Legislature or Congress. Maybe that will change over time, but there seems to be no urgency to tackle this issue now.

Q I bought my own Breathalyzer years ago out of curiosity and was amazed to find that I felt pretty toasted at 0.03 to 0.04. While I was happy to find I've likely never ever driven at anywhere near 0.08, it also made me realize just how generous the current 0.08 level really is. I remember the guy a few years ago who complained to you when he was busted for being exactly 0.08. I kind of felt some sympathy for him at the time, but that went away when I found out what the level really meant.

Steve Rempel

A Most folks, however, who contacted me over this issue were opposed to lowering the level to 0.05.

Q While I think drunken driving is terrible and I sympathize with people whose lives have been affected by drunken drivers, I can't see how lowering the limit to 0.05 will help. By lowering the limit, you pretty much guarantee that everyone who has a glass of wine with dinner would be subject to a DUI. I doubt the restaurateurs are happy about this suggested change.

A They are not, but ...

Q My wife and I have a wine travel site, WineQuesters.com, and have been to lots of wine-tasting events. Normally I spit and dump to limit alcohol consumption. That means taste the wine but spit it into a bucket and dump the remaining wine in a bucket.

I then test my blood-alcohol level and it usually reads around 0.03 percent.

As a test I didn't spit and dump at a tasting at Fort Mason a couple of years ago. My blood alcohol tester hit 0.08 percent. From just walking through the parking lot I felt I clearly could not safely drive and I was stunned that this is considered the legal limit.

I think 0.05 percent should be the limit.

A Our rule when Mrs. Roadshow and I are out: One glass of wine for the driver at the start of dinner and that's it.

Q What's going on at Montague Expressway at First Street in San Jose? The southbound shoulder has been dug up about a year and I've seen no progress in months. ... What are they doing at the railroad tracks on Montague Expressway in Milpitas?

A The city is waiting for a new sanitary sewer to be installed. Workers are also relocating utilities across the expressway in Milpitas to dig a trench for the BART-to-San Jose extension. This will take about a year.

Q You have solved so many traffic problems in Silicon Valley, I am hoping you can help solve this problem, as well.

Driving on Union Avenue between Camden Avenue and Bascom Avenue in San Jose in the early morning is like being in a bunch of bumper-to-bumper Indy cars on a curvy, two-lane racetrack. Traffic moves fast and cars in the center lane try to squeeze into the right-hand lane even though there is not enough space for a safe lane change.

The reason they want to change lanes is that the right-hand lane turns onto North Bascom Avenue and the center lane continues straight across Bascom toward Campbell Avenue. Drivers realize they are being forced into one direction or the other at the last moment, and a majority try to dive to the right onto Bascom, creating a hazard for all of us.

Can the center lane on Union be reconfigured so drivers have two choices: continue on Union or turn onto North Bascom?

Marylin Crawford

A The city will add extra striping on the road to alert motorists earlier to the need to change lanes. This should be done within a few days.
