Q Does the CHP list a minimum speed for the carpool lane? I try to go 55 to 60 mph so I have time to slow down if someone suddenly pulls into the carpool lane ahead of me on Interstate 80 between Richmond and Vallejo during commute times. When I go 55-60 mph, cars behind me flash their lights and want me to go 65, which I do not consider safe during commute times.

A There is no minimum speed limit, so go at a pace you feel safe. That can be 55 to 60 or lower when adjacent lanes are creeping along, but if you are slowing down a bunch of cars, either move over into the non-carpool lane if you can or go a tad faster.

Q My co-worker and I commute from Pleasanton to Fremont on Interstate 680. At least two or three times a week on we see highway patrolmen with at least two or three cars pulled over on Sheridan Road. Why?

A Look closely and you'll see stops also being made on Andrade Road. The CHP is nailing drivers who try to bypass I-680 on roads that parallel the freeway.

What are they getting nabbed for? Exceeding the 40-mph speed limit on Andrade, crossing solid double yellow lines, rolling through stop signs and passing on shoulders to get to the offramps.

Added Steve-the-CHP-Man:

"This might be a good opportunity to remind your readers that when seeking out an alternate route to a congested freeway, please modify your driving to correspond to the rules of the road you are on, not the freeway that you are attempting to avoid. Remember, those local roads are exactly that -- local. That means these roads have residents, businesses and others that use them for something other than an alternate commute route. It is where they live or work."

Q I have a question about the Fremont Street exit in San Francisco immediately after the Bay Bridge. On the first sign indicating the Fremont Street/Folsom Street exit, there is a sign which is covered with a large white board. Is this a planned future exit for that new bus terminal they're building?

A Yes. This is for a bus ramp to the Transbay Terminal due to open in 2017. It will say "Buses Only" with an arrow.

Q Your reader Tabitha Pousson inquired about radio stations that do traffic reports on I-680 and Highway 24. She might try listening to either KKIQ 101.7 (Pleasanton) or KKDV 92.1 (Walnut Creek). They have a more localized focus than bigger stations and, in fact, bill themselves as "your hometown station."

They also have a sister station, KUIC 95.3 in Vacaville, that focuses on I-80.

Q Please let Tabitha know about 511. You can call 511 from your cellphone (hands-free, of course) and it has voice-activated menus. After the main menu, say "traffic conditions" and then just name your road, like "Highway 24 west" or "Interstate 680 south." It will give you all the incidents: delays, accidents, lane closures, etc. I use it every day before I head home.
