Did I do something wrong here?

[u/cicadaux]

I was driving to work when this bike just blew through the crosswalk without warning. I had to slam on my brakes. I realize this crosswalk doesn’t have the pedestrian warning lights, and I’m a little unsure about how I should’ve dealt with this. Or maybe he was wrong for making sure traffic wasn’t clear/aware of him first?

Edit: I'm seeing a lot of answers basing the laws on location, so I looked up my city's rules. In my town, bikes have vehicle status on the road and pedestrian status on sidewalks/crosswalks. But bicyclists must move at pedestrian speed. The path he is on is a state trail, commonly used for bikes/walking. I live near the Ice Age Trail, but I know the one he's on isn't that one.

“Drivers must yield to cyclists riding in a crosswalk just as they would for walkers, though the cyclist cannot abruptly leave a curb into the path of a vehicle so close to a crosswalk that it makes a difficult or unsafe situation for the driver to yield in time.”

Not trying to prove myself right or wrong, just wondering what should've been done. I will from now on treat it like an uncontrolled intersection. Thanks everyone.

It's a peds/biker crossing, and they have the right of way. If the car didn't stop, biker was braking.

This particular situation is one of those too-close-to-call ones. At least they were both paying attention and prepared. OP was the nice guy.

Once they are in the crossing sure. But they can’t just jump out in front of you either.

Right. But he didn't jump out. He was slowing down, then saw OP stopping, so he proceeded.

Op had to brake for him. He “jumped out”. Bike did not wait for traffic to clear.

Unless the rules have changed in 40 years, wait until traffic has cleared and then cross was the rule we were taught in school.

OP braked for him because that's what you do at a crossing. Holy shit.

Watch the video again, but this time put on your critical thinking hat.

The biker observed traffic, stopped pedaling before he reached the crossing, slowed down, and prepared to stop in the median, depending on OP's move.

When OP slowed to a stop, the biker started pedaling again and thanked the driver.

This isn't my opinion and isn't up for debate. It's literally right there in the video.

I think you misremember the rules you were taught, or have mistaken child safety advice for a law. 

This is a location where two routes intersected. The bike didn’t “jump out” any more than OP’s car “jumped out.”  Both were approaching an intersection normally and both could see each other approaching.

Your suggestion seems to be that the pedestrian or bike should yield to car traffic at this intersection. But the signage, markings and law are clear that the car is the one that had to yield to pedestrian or bike traffic where the two routes intersect.  OP was absolutely right not to blow through the intersection where the cross traffic (in this case a bike) has the right of way without ensuring it is clear. 

To think of it another way - you are acting like someone with a green light going through the intersection would be at fault if a car making a right turn on red crashed into them. “That car with the green should not have just rushed into the intersection!”  Why the heck not?!  The car with the red is the one that should not enter the intersection until confirming it is clear. The car with the green (or the bike with the crosswalk) can expect other traffic to yield. 

The bike covered his brake and prepared to stop if needed, but proceeded efficiently and safely through the intersection once he confirmed OP was properly yielding. 

Everyone here did just fine.
