Waiting 3-seonds at a green light before proceeding
Waiting 3-seonds at a green light before proceeding
(OP)
Anyone have history, data or recommended practice information on the following:
"When the signal light turns green, the driver should remain stopped for 3-seconds of green, before starting into the intersection, to protect against cross-traffic drivers running their red light."
Evidently Bell Telephone Company's Safety Personnel use to instruct telephone company drivers to do this, as a matter of company policy. This same driver safety advise is again showing up in some corporate personnel safety training programs.
A concern with this advice being handed out again is present-day Actuated Left-Turn phasing timing-out on "snappy" timed signals about when the first driver starts to move in to the intersection, perhaps prompting disgruntled second & third queue drivers to run the following red light, since they expected to make the green light the first driver sat through.
Any official responses available on this one?

They go on to say you should wait two seconds after the vehicle in front of you starts to move, before moving.
Sometimes, this make sense, but many times, I think it adds unnecesarily to the signal's lost time.

For those drivers who actually think about what they are doing, the principle - drive so that you can avoid becoming a victim of others' mistakes - is probably a better lesson than the delayed acceleration technique. Those unwilling to think for themselves may need such rules.

If I remember correctly, a recent study indicated that most crossing accidents occur more than 3 seconds after the onset of cross street red, so this rule really may not reduce exposure.
