Traffic Signal Detectors Throwing You for a Loop?

Most intersections in OC have a detector to let the signal know someone is waiting. The most common is a loop of wire in the road that acts like a metal detector. California requires these sensors to detect one bicycle wheel – metal or carbon – but shifting pavement and rain degrade function. A coat of asphalt or slurry seal can reduce sensitivity and hide the location of the wires.

Here is what you need to know about getting a green light:

  1. The sensors are usually BEHIND THE LIMIT LINE. If stop in a crosswalk, you have broken the vehicle code and are likely past the sensor loop.
  2. They can pick up one wheel, but both wheels (or the wheels of more than one bike) should be on the wire.
  3. If the loop does not detect you, and no car or truck comes along, the best option is to use the crosswalk button. If you are already waiting in a left turn pocket, carefully cross to the corner on your left. Technically, you can only run the light if it is inoperable. Not sensing you does not mean inoperable in some cities, and people have been cited. You may prevail in court, but what a waste of time!
  4. Tell some one! The loops are adjustable, so contact the local city Director of Public Works. In unincorporated areas, contact OC Public Works. For freeway intersections, contact Caltrans. Copy us at infrastructure@OCBike.org, and we will try to help.

The Bicycle Tree Needs Help!

The Bicycle Tree in Santa Ana is a volunteer-powered nonprofit that helps bicyclists fix their own bikes, teaches bike repair, advocates for bike-friendly infrastructure and donates bikes to those in need. Sadly, the pandemic forced them to close for two weeks, and now they are open under a new system.

Despite their best efforts, their expenses are currently exceeding their income, and they need help more than ever. Will you please Make a Donation?The Bicycle Tree Graphic?

Seal Beach Blvd Bike Lane Closed

The popular bike lane on southbound Seal Beach Blvd is closed for a few hundred feet near Adolfo Lopez. That intersection is about halfway between Westminster Blvd and PCH, near the police station. Work will finish about December 24.

There are “Share the Road” signs in the area, but riders who aren’t in the mood to “share” with 50+mph traffic can turn west on Westminster, then take the San Gabriel River Trail or PCH south toward Seal Beach or beyond.

The northbound bike lane is open. The right-hand turn lane onto Adolfo Lopez will be lengthened and upgrades will be made to the traffic signal system at that intersection.
