Approaching construction on the highway? Experts say the "zipper merge" can help

Everybody has their own philosophy when it comes to merging in construction zones.

Conventional wisdom on the roads seems to be that when faced with an approaching merge, you should just get over as soon as you can and just wait for your turn like a good little driver.

The people whizzing by in the open lane are looked down upon - morally corrupt drivers making a BAD decision refusing to get in line and wait for their turn.

  • Creates a sense of fairness and equity that all lanes are moving at the same rate

It's kumbaya on the roadways. 

Don't try to be a traffic cop like this KUOW listener in Seattle:

If you do, you might just get a visit from this fella, and no one wants that:
