In the circumstance you just described, the provision you have quoted would not apply. The provision you cite applies when a car rear-ends a cyclist in the road. Basically it says, if you hit a cyclist, then you have violated the so-called “three foot rule.”

But if a cyclist blows through a stop sign and you hit them, the burden would actually be on them to show that they did not blow through the sign.

Oh, great! Another invitation for vacuously megalomanic cyclists to endanger themselves and other travelers by ignoring traffic laws or any semblance of self-restraint! Yesterday while driving east on Kinney Road I had to simultaneously hit the breaks and the horn to avoid hitting a cyclist who blew through the McCain Loop Road stop sign without slowing or even looking for traffic. Had I not been driving far below the speed limit, she would have decorated the front of my sedan, the county mounties would have “prima facie evidence” that the collision was my fault, and you would be reporting another tragic instance of an innocent cyclist run down by a neolithic “carhead”. Do cyclists EVER concede that they are responsible for their actions? Have you EVER cited in your blog an accident in which you agree the cyclist was at fault?

The current definition of a bicycle is:

“6. “Bicycle” means a device, including a racing wheelchair, that is propelled by human power and on which a person may ride and that has either:

(a) Two tandem wheels, either of which is more than sixteen inches in diameter”

This Bill adds:

“except that the wheels may be smaller if the bicycle is foldable.”

This Bill also adds to the definition of assault the following:

“Touching or throwing an object at or in the direction of any person riding a bicycle.”

As well as stuff like:

“C. If a collision occurs between a motor vehicle and a bicycle, the collision is prima facie evidence of the driver’s failure to leave a safe distance between the motor vehicle and the bicycle.”

“(ii) If no traffic is present in the lane, a driver may enter the lane a sufficient distance to provide the minimum three foot safe passing distance to bicyclists required by section 28-735.”

“F. If a driver of a motor vehicle violates this section and the violation results in a:

1. Minor injury to a bicyclist, the driver is subject to a civil penalty of up to five hundred dollars.

2. Serious physical injury as defined in section 13‑105 to a bicyclist, the driver is subject to a civil penalty of up to One thousand dollars.”

Sorry but I like this bill a lot better than stop signs.
Fault for not keeping 3 feet in an accident, fault for hitting me on a bike path, Allows cars to cross over into the center lane to over take, Allows me to ride a foldable bicycle, It takes away must ride in a bike lane, and adds assault to people who touch me or throw things at me.
Damn that is some great action there. Not to take away from other bills, but this bill is great.
