The Idaho Stop: Can Cyclists Treat Stop Signs as Yields?

The "Idaho Stop" allows cyclists to treat stop signs as yields and red lights as stop signs. Despite sounding dangerous, studies show it's actually safer.

What Is the Idaho Stop?

Stop Signs → Yield Signs Cyclists slow, check for traffic, and proceed if clear without fully stopping.

Red Lights → Stop Signs Cyclists stop, check for traffic, and proceed if clear (in some versions).

Why It's Called the Idaho Stop

Idaho passed the first such law in 1982. It remained unique for decades until other states started following.

Why It's Actually Safer

#

Physics

• Cyclists need more energy to restart from a stop

• Starting from a stop puts cyclists in intersection longer

• Rolling allows continuous observation

#

Visibility

• Moving cyclist is more visible

• Gets cyclist through intersection faster

#

Research Delaware study showed 23% decrease in cycling injuries after adoption.

Why Some Oppose It

- "Rules should be the same for everyone"

• Perceived as special treatment

• Confusion for drivers

• Enforcement challenges

If Your State Doesn't Have It

You still must follow current traffic laws. Running stop signs can:

• Result in tickets

• Create liability if you're in an accident

• Give insurance companies ammunition against your claim
