First and foremost, jaywalking is illegal.
However, does that mean a driver has the right to run you over? Simple answer: No.
Question: So who is at fault when a jaywalker is hit by a car?
Answer: Maybe both. Arizona law requires pedestrians to cross the street at corners and/or designated crosswalks.
So often, people decide on a quicker and less safe route. Indeed, I cannot even count the number of times I see someone jaywalking---yet with a marked crosswalk maybe 50 feet away.
Arizona law also requires drivers of motor vehicles to pay attention and to drive "reasonably" for all traffic conditions. "All traffic conditions" includes the existence of pedestrians in or near the roadways.
So, should an accident occur between a jaywalker and a car---if shown that the driver could have/should have seen the person and could have/should have been able to avoid, then without question the driver can be held responsible.
"Pay attention and drive reasonably for all traffic conditions".
If on the other hand it seems unlikely that a driver should have avoided---as in a case where the pedestrian darts right out into traffic, then it may be that the pedestrian will be deemed 100% at fault for his/her injuries.
